Name
Carnus Nitzsch, 1818

Carnus hemapterus

Carnus is a genus of flies (Diptera) with 5 described species, all of which are parasites of birds.[3] The adult flies locate a suitable host nest, then shed their wings and feed on the blood of the developing nestlings.[4] Mature female flies lay their eggs in the nest, where their larvae develop on organic detritus.[4]
Species

C. floridensis Grimaldi, 1997[5][3]
C. hemapterus Nitzsch, 1818[1][3][6]
C. mexicana Grimaldi, 1997[5][3]
C. occidentalis Grimaldi, 1997[5][3]
C. orientalis Maa, 1968[7][3]

In 2014, C. orientalis was reported for the first time in Japan, parasitizing nestlings of the Ryūkyū scops owl, Otus elegans, a new host species record.[8]
