Apedilum elachistus Townes

NEW STATE RECORD

Wolff (2002) reported collecting pupae of an unidentified species of Apedilum during a survey of the invertebrates living in streams on Oahu. The adults identified here most likely represent the same species. A. elachistus is widespread in North America . Larvae are blood worms and live in eutrophic sediments in streams and shallow water bodies. When abundant, the swarming adults can become a nuisance.
