Porismus strigatus, copyright Donald Hobern.

Belongs within: Euneuroptera.

The Osmylidae are a diverse group of moderate-sized to large lacewings that typically have camouflaging patterns on their wings. Larvae are long and slender with elongate, lance-like jaws and are most commonly found in moist riparian habitats. Some members of the clade Osmylomorpha have larvae living in drier locations (Engel et al. 2018).

Characters (from New 1991): Generally medium to large (fore wing length 12-30 mm or more), with wings often patterned with grey or brown and rather broad; antennae usually less than half as long as fore wing; three ocelli present, at least represented by raised tubercles on vertex; female genitalia with enlarged gonocoxite 9, and 2 spermathecae. Larvae long and fusiform, with long tapering straight jaws.
