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