blepharoceridæ

Century Dictionary and Cyclopedia

1. A family of small bibionoid dipterous insects which have the wings furnished with a network of creased lines, from which they have been called the net-veined midges. The adults are mosquito-like in form, and the larvæ, which are aquatic, resemble crustacea more than insects. They attach themselves to rocks in swift-running streams, and have apparently but 7 segments.
