Hydroptila apalachicola

Description

Hydroptila apalachicola is a species of microcaddisfly. It is only known from three adult males collected from cold spring-fed streams in the Apalachicola National Forest, Florida. This is a tiny brown caddisfly up to 3.2 mm in length and can only be distinguished from its closest relatives by minute differences in the structure of the tenth abdominal tergum.
