New Brunswick, York Co., Mazerolle Settlement, 45.8765°N, 66.8260°W, 8.VI.2008, R. P. Webster, beaver meadow, sweeping vegetation along brook margin (1, RWC).

This species has been collected from leaves and stems of pondweeds (Potamogeton sp.) (Potamogetonaceea) (Askevold 1987) and from leaf litter beside small lakes from October to the first snow (L. LeSage, personal observation). Neohaemonia species occur mostly in lotic sites near streams and are often submerged, and thus, are rarely collected (Askevold 1987). Larvae are submerged and feed on the stems and roots of Potamogeton (Hoffman 1940). The single adult from New Brunswick was collected by sweeping vegetation along a stream margin in early June.

This species has been collected from leaves and stems of pondweeds (Potamogeton sp.) (Askevold 1987) and probably has a similar biology as Neohaemonia melsheimeri. One adult from New Brunswick was swept from foliage along a lake margin during June.

Larvae mine the leaves of black locust and other woody species of Fabaceae. Adults also feed on black locust and other Fabaceae but have been collected from many other tree species (Clark et al. 2004; Staines 2006).

Adults from New Brunswick were collected from the foliage of Leucanthemum vulgare Lam. (ox-eye-daisy) in open disturbed roadside sites near a red pine (Pinus resinosa Ait.) and a jack pine (Pinus banksiana Lamb.) forest. Specimens were also collected in the late fall on a paved road during warm afternoons. Adults were collected during June, September, and October.

AK, YT, NB (Riley et al. 2003). The population in New Brunswick is likely an adventive Palaearctic species known from Europe, Siberia, the Far East, and Alaska (Bieńkowski 2001).

Chrysolina finitima Brown, 1962 was placed in synonymy with Chrysolina marginata marginata (Linnaeus) by Bieńkowski (2001: 152), a synonymy accepted by Riley et al. (2003) in their catalog. It makes sense for specimens from Alaska or Yukon to belong to the nominal Palaearctic subspecies since this state and province can be considered as the easternmost part of the natural distribution of Chrysolina marginata that extends over the Bering Detroit into the New World. On the other hand, the presence of Chrysolina marginata in New Brunswick is not natural and is undoubtedly the result of a recent introduction into eastern Canada, which is not yet fully documented (LeSage, personal observations). Considering that there are nine Palaearctic subspecies (Bieńkowski 2011), it might be advisable not to use a subspecies name until our eastern population can be properly assigned to a subspecies.

The main host plants of Chrysolina laurentia are Salix sp., with known preferences for Salix discolor Mühl., Salix interior Mühl, Salix lucida Mühl., and Salix petiolaris J.E. Smith (LeSage 1996), but poplars (Populus sp.) are also accepted (Brown 1956). In New Brunswick, this species was collected by beating foliage of Salix or sweeping foliage along river margins. Adults were collected during June and August.

Prasocuris vittatus was collected by sweeping foliage along a roadside and forest trail, in a small marsh with Carex, and near a small stream. However, the true host is probably buttercup (Ranunculus acris L.) on which both larvae and adults were found and reared by the second author. Ranunculus acris and Ranunculus repens L. (Creeping buttercup) were reported as hosts for this species by Clark et al. (2004). Adults were collected during June and July.

Adults of this species were swept from foliage along a lake margin and a river margin. Adults were defoliating Alnus at the site south of Beaver Dam. This species was taken during June, July, and August.

BC, AB, MB, ON, NB, NS, PE (Riley et al. 2003). This is a Palaearctic species now widely established throughout much of the northern half of the USA and Canada (Riley et al. 2003). It was introduced, together with Neogalerucella pusilla (Duftschmid), for the biocontrol of purple loosestrife (Lythrum salicaria L.) and has been successful in controlling this weed (Hight et al. 1995). Consequently, its presence on alder is incidental and the damage to the leaves may have been done before by the alder flea beetle (Altica ambiens alni Harris), which is closely associated with this bush (LeSage 1995).

Mantura chrysanthami was swept or beaten from foliage from a variety of habitats in New Brunswick. These included a barrier beach, a jack pine forest, an old sand dune with red oaks (Quercus rubra L.), a power-line right-of-way, and a mixed forest. A small series was swept from the foliage of sheep sorrel, Rumex acetosella L. Adults were captured during June, July, and August. Based on personal observations and collecting by the second author in the Ottawa, ON area, Mantura chrysanthemi is monophagous on Rumex acetosella both in the larval and adult stages.
