Cistogaster globosa on Tachinid Recording Scheme website
C. globosa was allocated RDB1 status by Shirt (1987) and Falk (1991). The most recent review (Falk & Pont in preparation) has provisionally accorded the species RDB2 status. It is known from a few localities in Southern England and is a distinctive species unlikely to be overlooked and probably genuinely rare. The species parasitises heteropteran bugs, in Europe the shieldbug Aelia (Pentatomidae), mostly A. acuminata (Belshaw 1993), the only species of the genus found in Britain. The egg is laid on the dorsal surface of the host's abdomen and the larva leaves the host to pupate in the ground. The fly appears to favour dry grassland where the host is predominately found (Raper & Smith 2002). Howe & Woodman (2001) report that individuals have been seen nectaring on Carrot in Wales, and that is also the case in Essex. The abdomen of the female is black, whereas the male's is orange with black markings. References
