Nostima is a genus of shore flies in the family Ephydridae. ^{[2] [3]}

Description

Nostima are small flies with body lengths ranging from 0.72 to 1.72 mm. They often have patterns of microtomentum (fine hairs) on the body as well as patterns on the wings. The genus can be distinguished from related genera by a lack of acrostichal setae ( Garifuna has 2 rows of these setae and Philygria has 1 row) and a lack of presutural dorsocentral setae (present in Philygria). ^[2]

Ecology

Larva of this genus are semiaquatic and feed on blue-green algae, while the adults usually occur in grassy habitats. ^[4]
