The genus
The larvae of several species are associated with bracket fungi, other fungi, decaying wood infested by insects and decaying vegetable matter, as well as in bird’s nests (
The studied material was collected in 2010 and 2014 by the authors in Vráž (near Písek), and it is deposited in the collections of the Czech University of Life Sciences, Prague. The specimens were collected by pyramidal traps as illustrated in Fig.
Pyramidal trap.
Sawdust trap baited with oak sawdust.
Species with head 1.25× as deep as long, first flagellomere 1.3× as deep as long, body yellow with three black partly fused stripes, central stripe reaching scutellum and scutellum often dark.
Named in honour of Archbishop of Břevnov Monastery Petr Prokop Siostrzonek, a supporter of natural science and our friend.
