Twelve species of shore flies have larvae that can utilize blue-green algae (Cyanophyceae) as food. Setacera atrovirens (Loew) and S. pacifica (Cresson) were reared from Nostoc and Anabaena, respectively. Scatella stagnalis (Fallén) was obtained from Nostoc colonies. Larvae of 3 species of Hyadina, 4 species of Lytogaster, and Pelina truncatula Loew were reared from colonies of soil-inhabiting species of Cylindrospermum. Larvae of Axysta cesta (Haliday) were found in a colony of Lyngbya growing on moist tree leaves near a shaded pond. Species of Hyadina, Lytogaster, and Axysta appear to be trophic specialists, as they have been reared only from colonies of blue-green algae. In contrast, the 2 Setacera species and S. stagnalis are polyphagous, having been found to ingest a wide mix of cells belonging to several different algal classes.
