'Blephariceridae', commonly known as 'Net-winged midges', are a
nematoceran family in the order
Diptera. The adults resemble
crane flies except with a projecting anal angle in the wings, absence of the V on the mesonotum, and more laterally outstretched forward facing legs. They are uncommon, but there are dozens of genera worldwide, and over 200 species.
They are found near fast flowing streams which the
larvae inhabit. Blepharicerid larvae are filter feeders and have suckers on their abdominal tergites, used to adhere to rocks in the torrents in which they live. These suckers are sometimes called
creeping welts. These are of unique evolutionary origin within the
Diptera.
One recent classification based largely on
fossils treats this family as the sole member of its infraorder, but this has not gained wide acceptance.
