Order Neuroptera (Lacewings)

Code QN059999

These small lacewings lay their eggs on vegetation overhanging water. The larvae hatch and drop to the water and search out freshwater sponges on which they are specialised predators. Pupation takes place away from the water.

Sisyrid larvae are shorter and less elongate than the other families covered in this key (length to 10mm, body length/width ratio about 3:1). A series of leg-like gills held folded against the underside of the abdomen distinguishes the larvae from any other.
