Synonymy.—Sarcophaga sternodontis (Towns.).
Hoffman (1927) claimed that approximately 40 percent of some specimens of Pycnoscelus surinamensis collected in southern Haiti were parasitized by S. lambens. However, according to entomologists at the University of Puerto Rico Agricultural Experiment Station, Hoffman was incorrect in his observations: S. lambens was never reared from a living insect and had been recovered only from dead cockroaches and other dead insects and was considered saprophytic rather than parasitic (Schwabe, 1950b).
Sarcophaga spp.
Sanjean (1957) reared various species of sarcophagid larvae on Periplaneta americana which were freshly killed or chopped up; first instar larvae were also introduced into the body cavity of cockroaches which had their heads and legs removed. Adult sarcophagids were collected and freshly killed American cockroaches used as bait.
Order COLEOPTERA

Harpalus pennsylvanicus De Geer
Experimental prey.—Cryptocercus punctulatus, U.S.A. (Cleveland et al., 1934): This beetle is often found in the galleries of C. punctulatus in nature. In the laboratory it killed and devoured cockroaches as large as itself.
