Add a sighting Subscribe View significant

ADULTS: moth-like, but with membranous wings; short-lived

LARVAE: aquatic; useful indicators of water quality, as they are sensitive to pollution; many build portable, protective cases from sand or vegetation; the structure of the case may help identification to family, or even genus level

Identification guide for larvae: The Waterbug App. This is a very helpful guide for identifying aquatic invertebrates - including larval insects such as caddisflies. The App is free, and available for iOS and Android devices.
