The puparium of Meoneura lamellata Collin (Diptera, Carnidae) and records of three other carnids from bird and mammal nests

Abstract

• Rearing data for four species of Carnidae (Diptera) are presented from material obtained in the 1930s by E.B. Basden. 387 specimens of the Meoneura lamellata Collin, 1930 were reared, almost exclusively from nests of the sand martin, Riparia riparia. 533 specimens of the Meoneura neottiophila Collin, 1930 came from nests of 14 bird species and grey squirrel, Sciurus carolinensis. 344 specimens of Carnus hemapterus Nitzsch, 1818 came from 3 bird speies and 2 specimens of Meoneura vagans (Fallen, 1823) were reared from dung of the pheasant, Phasilanus colchicus. The puparium of M. lamellata is described and compared with that of M. neottiophila and C. hemapterus.
