Hydroptilids display various structural adaptations to the wide range of aquatic environments they occur in, making them one of the most diverse caddisfly families regarding the form of larvae and larval cases (Marshall 1979b). In Nielsen’s (1948) classic work on hydroptilid larvae, he gave a very detailed account of larval morphology and biology; unfortunately, it is a fairly limited view of the family as a whole, since he expounded on only five of the more specialized genera within Hydroptilidae (Agraylea, Hydroptila, Ithytrichia, Orthotrichia, and Oxyethira). However, Nielsen’s work laid an excellent foundation for future trichopterists and made Marshall’s (1979b) more general account of larval morphology possible.

One of the characteristic features of hydroptilid larvae is the simple form of hypermetamorphosis they undergo. Marshall (1979b) commented that it had not been confirmed if ptilocolepid larvae also undergo hypermetamorphosis, but it has since been confirmed that ptilocolepids do experience the same changes, although not as pronounced as those of the hydroptilids (Wells 2010b). Early instars I–IV of both families are relatively smaller (0.5–2.7 mm in length), of short duration, and caseless, i.e., “free-living”, while final instar V is larger (2.0–7.0 mm in length) and constructs a portable or secondarily fixed case (Marshall 1979b). The final instar also functions as the primary feeding and growing stage in the hydroptilid life cycle, during which the abdomen becomes greatly enlarged (Marshall 1979b) or physogastric. The early instars I–IV can be characterized by features associated by their absence of a case, including narrowly tapering abdomens, freely projecting anal prolegs; the long, fine setae on the body can offer resistance to sinking and help the larva to swim and disperse (Marshall 1979b). The duration of these free-living stages is usually much shorter than the final instar. In only a very few species is the final instar also free-living.

The case-building larvae of instar V are prognathous and campodeiform, similar to the “saddle-case” bearing glossosomatids, as opposed to the hypognathous and eruciform “tube-case” building families (Marshall 1979b). Instar V tends to be more easily identified and distinct among the genera and can be separated from all other Trichoptera larvae by a combination of features, including the enlarged abdomen, three pairs of well-developed thoracic tergites, the absence of segmentally arranged tracheal gills, fusion of the well-developed abdominal prolegs to the sides of abdominal segment X, and, while the number of abdominal tergites may vary, one is always present on abdominal segment IX (Marshall 1979b; Wiggins 1996). Hydroptilid larvae have dorsal sclerotized rings on abdominal segments II/III to VII/VIII which have not been recorded in ptilocolepid larvae; these rings may be regions of specialized chloride epithelial cells adapted for ion absorption and osmoregulation (Wichard 1976; Wiggins 1977). Features of the thoracic legs of instar V have proven useful at the generic level in hydroptilid taxonomy; for example, though basically ambulatory, they may be modified to be robust for clinging to substrate in swiftly moving waters, long and slender in vegetation dwellers, or may bear a specialized process that aids in the manipulation of algal filaments (Marshall 1979b). In instar V, the abdomen becomes hugely distended; the overall form and shape of the abdominal expansion is unique and typically characteristic for each genus (Marshall 1979b). Unique among trichopteran, members of the genus Orthotrichia have a pronounced triangular ‘tooth’ on the larval labrum.

The larval case constructed during the final instar is often referred to as a “purse-case”, a term coined by Ross (1967) to separate hydroptilid cases from glossosomatid “saddle-cases” and phryganidean (sensu Thomas et al. 2020) “tube-cases”. The typical “purse-case” consists of two closely apposed silken halves into which various organic or inorganic particles may be incorporated; the two halves are joined along the lateral margins, leaving narrow openings at the anterior and posterior ends, and may be either laterally or dorso-ventrally compressed (Stephens 1836; Marshall 1979b). As the larval abdomen increases in size during the final instar, the case is expanded by splitting the margins, adding new layers of silk, and then resealing them (Nielsen 1948; Wiggins 1996).

As in most Trichoptera, hydroptilid pupae are exarate, dectitious, and do not offer many features useful for identification past the family level (Marshall 1979b). Aside from the absence of any structural features used to positively characterize other caddis families, hydroptilid pupae might be recognized by the absence of abdominal gills or lateral lines, the presegmental dorsal abdominal plates on segments III–VII, the postsegmental plates on segments III–V, and their relatively small size (1.5–6.0 mm in length) (Marshall 1979b). Overall, the pupal case is similar to the larval case, but firmly attached to the substrate with the anterior and posterior openings sealed; once the case is attached and sealed, the larva spins one final internal lining and adopts a characteristic resting posture in which the thorax becomes distended, the abdomen straightens, and the intersegmental grooves become less obvious (Barnard 1971). Ptilocolepid and hydroptilid pupae can be separated based on the presence or absence of medial teeth on the mandibles: in Hydroptilidae medial teeth are absent, while in Ptilocolepidae either one (Palaeagapetus) or two (Ptilocolepus) teeth are present (Marshall 1979b).

Features that comprise the generally accepted typical hydroptilid form include small size (1.2–6.0 mm forewing length); narrow, pointed wings with long setal fringes along the anal margin and reduced venation; a dense layer of setae on the wings and body parts creates a general appearance of pubescence (Stephens 1836; Marshall 1979b). While most genera bear setae that are white and either black or brown in hue, giving them a mottled appearance, some tropical genera are known to exhibit patches of distinct metallic hues. As the overall size of genera decreases, the wings also become reduced, leading to decreasingly distinct venation and increasingly longer setal fringes that compensate for the loss of wing membrane area (extreme examples or reduced wings and venation can be seen in the genera Chrysotrichia and Neotrichia) (Stephens 1836; Marshall 1979b). Because of this reduction in venation, venational features that are of taxonomic importance in other families of larger caddisflies are not constant in hydroptilid genera and are considered unreliable taxonomic characters.

On the head capsule, dorsal ocelli vary from none to two or three and, posteriorly, there is typically a pair of dorsal postoccipital lobes or warts which may be modified as eversible scent-dispersing organs (e.g., Hydroptila). In some genera (e.g., Leucotrichia), the head may bear modifications, such as patches of scales or setiferous protuberances. Antennal segments, typically the basal-most, in some genera may also be modified to appear elongated or enlarged. On the thorax, the angular warts and near-vertical posterior face of the mesoscutellum are distinct characters for the family. Additional taxonomically important features on the thorax at the subfamily and generic levels include the shape of the meso- and metathoracic nota and the presence or absence of transverse sutures. The posterior mesothoracic katepisternal suture is typically present in ptilocolepids and absent in hydroptilids, a feature first noted by Ross (1956) and later confirmed by Marshall (1979b). Wings of some genera may also bear modifications (e.g., Peltopsyche, Costatrichia), such as patches of scales or a costal “pouch” or “bulla”. The spur formula, which refers to the number of spurs present on the tibiae, is another important diagnostic feature used in hydroptilid taxonomy. The formula indicates the number of spurs on the fore-, mid-, and hind tibiae, respectively, with four being the maximum number of spines on any one leg (two preapical and two apical) (Marshall 1979b); for example, the formula for the genus Leucotrichia is 1, 3, 4.

The hydroptilid abdomen consists of the typical eleven basic segments, with segments X and XI generally being regarded as one, and the sclerites of the posterior segments modified to form the genitalic structures, which provide features of taxonomic importance at both the generic and specific levels; most hydroptilid species are known from male specimens only. Segment IX forms a distinct genital capsule with a membranous posterior concavity, out of which originates segment X, the phallus, and any ventral appendages (Marshall 1979b). Segment X is present as a tergite only, is usually completely membranous but may be weakly sclerotized, varies considerably in size and shape, and may fuse ventrally with structures beneath the phallus to form a structure known as the “phallic tube” or “phallocrypt” (Marshall 1979b). Inferior appendages, often referred to as “claspers”, are single-segmented, in contrast to the 2-segmented condition generally found in many other caddis families, and vary greatly in size, shape, and whether or not they bear additional processes or setae; these appendages can provide taxonomically important features at both the generic and specific levels (Marshall 1979b). The phallus (also sometimes referred to as the aedeagus, penis, or copulatory organ) is essentially a long, slender, sclerotized tube that varies structurally between groups. In the Hydroptilinae, Neotrichiinae, and Orthotrichiinae, the phallus bears a spiral “titillator” and is divided into a proximal half bearing an ejaculatory duct and a distal half bearing an intromittent organ. In Leucotrichiinae, the phallus bears a complicated median complex with “windows”, “loops”, and a membranous apex. In Ochrotrichiinae, the phallus may be very slender or heavily spined, whereas in Stactobiinae, the phallus is essentially a common median duct bearing a pair of lateral processes that may be fused (Marshall 1979b). Overall, not much is really known about the comparative morphology of hydroptilid male genitalia, and the terminology of different structures varies greatly between authors. For example, Marshall (1979b) uses the term “subgenital” to refer to any structures occurring ventral to the phallus; when separate and paired, she calls them “appendages” (which have been referred to variously as “intermediate appendages”, “lateral penis-sheaths”, or “parameres”) and when they are fused refers to the structure as a “plate” (“lower penis cover” or “ventral plate of X”). Oláh and Johanson (2008) argued for the use of appendicular terminology (“gonopods”, “paraprocts”, “cercus”, etc.) over the directional terms (appendages referred to as “inferior”, “intermediate”, “superior”, etc.). Their work, however, addressed Trichoptera as a whole and did not address the complex genitalia of Hydroptilidae in specific, as Marshall’s (1979b) monograph did. Further work regarding hydroptilid male genitalia is needed to infer the homology of these structures.

Female genitalia of hydroptilids are of the generalized trichopteran condition, a simple “telescopic ovipositor” or “oviscapt” which consists of modified abdominal segments VIII–X and a gonopore occurring ventrally between segments IX and X (Scudder 1971; Marshall 1979b). The posterior margin of the ringlike segment VIII provides features that can be of taxonomic importance, such as dorsal and ventral processes or rows or setae (Marshall 1979b).

While some of the above description can be extended to the ptilocolepids, there are some fundamental differences that can be used to differentiate between the two families. Although ptilocolepid larvae closely resemble those of hydroptilids, the adults look more similar to small rhyacophilids or glossosomatids. They are relatively larger than hydroptilids (4.0–6.0 mm in length) and their wings are relatively broad with rounded apices and short marginal setal fringes (Marshall 1979b). The wings also boast a much more complete venation that resembles that of primitive rhyacophilids, differing in the subcosta of the forewing and the fusion of various veins in the hindwing (Ross 1956). Ptilocolepid venation differs from hydroptilids by the presence of a distinct discoidal cell, separate M₃ and M₄, and a forked Cu₁ in the forewing (Marshall 1979b). Additionally, ptilocolepids bear short, unmodified macrotrichia in a sparse, scattered distribution on their body, which gives them more of an overall granulose appearance, rather than pubescent.

The family Hydroptilidae was established in 1836 by Stephens for the genera Hydroptila, Agraylea, and Narycia. However, the only species of the genus Narycia that was figured, Narycia elegans, subsequently proved to be a moth from the family Psychidae. The remaining genera, Hydroptila and Agraylea, could be distinguished from other trichopteran families by the “cleft-like” openings of the larval cases and by the filiform antennae and unfolded posterior wings of the adults (Marshall 1979b). The cases and larvae of Hydroptila pulchricornis and Oxyethira flavicornis had actually been described previously by Pictet (1834) as a unique taxon under the general name “les Hydroptiles”. For this reason, McLachlan (1880) considered Pictet (1834), and not Stephens, to be the true founder of the family Hydroptilidae.

In 1948, Nielsen made the first attempt to divide Hydroptilidae, which was proving to be a large and heterogeneous group, into subfamilies. Based on morphological similarities of the larvae, he proposed the subfamilies Orthotrichiinae for the genera Ithytrichia and Orthotrichia and Hydroptilinae for the genera Agraylea, Hydroptila, and Oxyethira. While other genera, such as Ptilocolepus and Stactobia, had been established by this time, Nielsen commented on their relative position within the family but declined to formally place them in either of his proposed subfamilies. At this time, Nielsen also placed Hydroptilidae between the “saddle-case” building Glossosomatinae and the “tube-case” building Integripalpia, based on features of the larvae and pupae. In this work, Nielsen described in great detail the morphology, life histories, and feeding and case building behaviors of five microcaddisfly genera, which provided a very accurate, but fairly restricted, overview of microcaddisflies in general.

Botosaneanu (1956) established the subfamily Stactobiinae for the previously unplaced genus Stactobia and what he referred to as “its immediate relatives”, which most likely included the genera Plethotrichia, Plethus, Lamonganotrichia, Stactobiella, and probably Catoxyethira (Marshall 1979b).

In Ross’s (1956) new classification, the “purse-case” making hydroptilids, included in the “case-maker division”, were divided into the subfamilies Ptilocolepinae for the genera Palaeagapetus and Ptilocolepus, and Hydroptilinae for the remaining genera; Hydroptilinae was further divided into the tribes Hydroptilini and Neotrichiini. Flint (1970) later declined to follow Ross’s (1956) classification and proposed another new classification with the subfamily Leucotrichinae (subsequently corrected to Leucotrichiinae) for the genus Leucotrichia and its related genera and retained Hydroptilinae, Orthotrichiinae, Ptilocolepinae, and Stactobiinae as separate and distinct subfamilies.

Marshall (1979b) provided the first review of Hydroptilidae at the generic level, including all 42 genera described at the time. For each genus, she included information regarding nomenclature, distribution, morphology of adult and immature stages, biology, and possible species groupings. Marshall also provided keys to the subfamilies, at the time considered tribes, for the adult stage and to the genera for both the adult and immature stages. She discussed the phylogeny of the family and offered a new classification. Marshall’s proposed classification was based on that of Ross (1956) by recognizing only two subfamilies, Hydroptilinae and Ptilocolepinae. However, it also reflected the classification proposed by Flint (1970) by dividing Hydroptilinae into six tribes that corresponded to the subfamilies he had proposed: Hydroptilini, Leucotrichiini, Neotrichiini, Ochrotrichiini, and Stactobiini, and the newly proposed Ochrotrichiini. The morphology-based phylogeny proposed by Marshall was not backed by any statistical analyses and therefore offered no support values for any of the proposed relationships. Marshall’s phylogeny represents the last attempt to assess the relationships of the subfamilies and genera of Hydroptilidae as a whole.

In 2010, Wells wrote a review of hydroptilid studies published from the time of Marshall’s (1979b) review up through 2009; in this work, she reviewed hydroptilid taxonomy, included new discoveries regarding aspects of the biology of some species, and suggested that future work should place emphasis on life history studies.

In 2011, Oláh and Johanson produced a paper in which they described many new species from the Neotropical faunal region and referred to the subfamilies as tribes. In this work, Oláh and Johanson provided several tables containing either features or character states of species groups, subgenera, generic clusters, or genera in tribes. However, the tables did not cover all of the taxa present in the paper, no information on generic features or character states was provided for Hydroptila or any of the included stactobiine genera (Bredinia, Flintiella, and Orinocotrichia), nor was there any discussion of the information outlined in the tables. As interpreted from the tables, several genera were transferred between subfamilies or from incertae sedis status.

The most recent update to hydroptilid classification was based on a phylogenetic assessment of Leucotrichiinae using both molecular and morphological data (Santos et al. 2016a). The nomenclatural modifications proposed in the paper included the recognition of two tribes within Leucotrichiinae, Alisotrichiini, and Leucotrichiini, one generic synonymy, and one newly established genus. Santos et al. also discussed potential convergent evolution between Leucotrichiinae and Stactobiinae in this work.

The family Ptilocolepidae, which was once considered to be a group within Hydroptilidae and is considered in recent classifications as a distinct family, includes the genera Ptilocolepus and Palaeagapetus. The type species was originally described in Rhyacophila and therefore placed in the family Rhyacophilidae (Pictet 1834), but was subsequently shown to be a senior synonym of Ptilocolepus turbidus, making the type species Ptilocolepus granulatus (Hagen 1855). Thienemann (1904a) noted similarities between the larvae of P. granulatus and both members of Hydroptilidae and Glossosomatidae, which led Ulmer (1907) to transfer the genus to Hydroptilidae. Subsequently, Martynov (1913b) established the subfamily Ptilocolepinae for Ptilocolepus, but it was retained in Rhyacophilidae. Ross (1956) transferred Ptilocolepinae to Hydroptilidae and redefined it to include Palaeagapetus (incorrectly referring to it as Palaeagapetinae). Kristensen (1997) suggested that Ptilocolepus and Palaeagapetus together may represent the sister group of all other Trichoptera.

In 2001, Ptilocolepidae was elevated to the family status, which is currently recognized, effectively also elevating each of the six tribes within Hydroptilinae to the rank of subfamily (Malicky 2001b). Malicky claimed that previous authors had placed differing levels of importance on morphological features of either the adults or the larvae, which led to the group being placed in different families at different times. He stated that, because all these characters should be considered equally, it was appropriate to raise the group to family rank of Ptilocolepidae. Subsequently, the deeper-level relationships within Trichoptera were explored using molecular data and both the monophyly of Ptilocolepidae and its status as a family were questioned (Holzenthal et al. 2007a). According to the work of Holzenthal et al. (2007a), Ptilocolepidae consistently groups with Hydroptilidae, indicating that the elevation to family status might be an unnecessary taxonomic change. Malicky (2008b) countered by referring to the differences in geographical distribution of the two families, stating that the high level of endemism shown by Hydroptilidae and the relictual distribution of Ptilocolepidae were additional evidence that the families are distinct from one another. In their work resolving a higher-level phylogeny of Trichoptera based on multiple genes, Thomas et al. (2020) concluded that Ptilocolepidae is a monophyletic unit, sister to Hydroptilidae.

Acanthotrichia is a monotypic genus occurring in Australia. Based on features of the male genitalia, it was placed in Hydroptilinae and may be most closely related to the genera Tricholeiochiton and Paroxyethira (Wells 1982). The larval stage was described by Wells (1985b).

Acritoptila consists of 16 species occurring in Australia and New Caledonia. It can be distinguished from members of Austratrichia and Mulgravia by differences in the inferior appendages of the male genitalia (Wells 1982). Wells (1985b) described the larvae of A. globosa and A. margaretae and stated that the larvae of Acritoptila are indistinguishable from those of Hellyethira.

The genus Agraylea currently contains two subgenera. The subgenus Agraylea consists of eleven species, including three fossil species known from Baltic amber, and has a Holarctic distribution. The subgenus Nanoagraylea consists of three fossil species (Botosaneanu 1995b). According to Marshall (1979b), the extant members of the genus are most similar morphologically to Allotrichia, from which they differ in hindwing venation, but features of the male genitalia are similar to those of the genera Dhatrichia and Ugandatrichia. Larval descriptions of A. cognatella, A. multipunctata, and A. sexmaculata were given by Solem (1972), Nielsen (1948), and Barnard (1971), respectively.

Allotrichia consists of 14 species, including four fossil species known from Baltic amber. The genus has a Palaearctic distribution. Marshall (1979b) noted that the genus is morphologically very similar to Agraylea, and that Agraylea may be a junior subjective synonym of Allotrichia. The larvae of A. pallicornis were described by Giudicelli and Vaillant (1967).

Austratrichia Wells, 1982: 259 [type species: Austratrichia neboissi Wells, 1982, original designation].

The monotypic genus Austratrichia is endemic to Australia. It is most similar to the genus Hellyethira. According to Wells (1982), the genus can be distinguished using characters of the male genitalia (Wells 1982). The larval stage is unknown.

Cyclopsiella Kjærandsen, 1997: 234 [type species: Cyclopsiella anderseni Kjærandsen, 1997, original designation].

The monotypic genus Cyclopsiella, recorded only from Ghana, can be distinguished from all other hydroptilid genera by having only a single medial ocellus and lacking postoccipital lobes (Kjærandsen 1997). Kjærandsen (1997) noted that the male genitalia of Cyclopsiella share some similarities with the genera Hydroptila and Hellyethira, yet, in the accompanying parsimony analysis, Cyclopsiella grouped with the genera Jabitrichia, Oxyethira, and Tangatrichia. The larval stage is unknown.

The genus Dhatrichia consists of 14 species recorded from Burkina Faso, Ghana, Madagascar, Tanzania, Yemen, and Zaire. Marshall (1979b) stated that Dhatrichia shares similarities in the male genitalia with Agraylea and in the thorax with Microptila, Kjærandsen (2004), however, postulated that the genus is actually sister to either Kumanskiella or Microptila, although Kumanskiella is currently placed in the Neotrichiinae. The larvae of D. ankasaensis, D. hunukani, D. lerabae, D. minuta, and D. wliensis were described by Kjærandsen (2004).

The genus Hellyethira consists of 44 species, 30 occurring in Australia (one of which is also found in New Caledonia), others in New Guinea and Southeast Asia, and a single species described from Ethiopia. It can be distinguished from the genera Paroxyethira and Orthotrichia by differences in wing venation (Neboiss 1977). Wells (1985b) stated that the larvae of the genus are indistinguishable from those of Acritoptila; she described the larval stages of H. simplex and final instar larvae of many others in the genus.

Hydroptila is a large, cosmopolitan genus occurring in all regions excluding polar regions. It is the most species-rich genus in the family, consisting of 495 extant species and one fossil species. Marshall (1979b) divided Hydroptila into thirteen species groups (capensis, consimilis, dikirilagoda, forcipata, losida, occulta, pulchricornis, sparsa, tigurina, tineoides, uncinata, vectis, waubesiana) which she thought might one day be recognized as subgenera, based on distribution and form of the male and female genitalia. Despite the large number of species and the proposed species groups, she also listed several characters that unite the genus, including basic structure of the genitalia, thorax, absence of ocelli, presence of dorsal postoccipital scent-organs in male adults, and the general appearance of the immature stage. The larvae of H. delineata were described by Sibley (1926), and larvae of many other species have been described since (Lepneva 1932, 1964; Ross 1944; Nielsen 1948; Hanna 1961; Jacquemart and Coineau 1962; Botosaneanu and Sykora 1963; Flint 1964; Jacquemart 1965; Hicken 1967; Fahy 1971; Ito and Kawamura 1980; Botosaneanu and Giudicelli 1981; Wells 1985b, 1997; Keiper and Foote 1999).
