We have not studied the species under* conditions occurringin the Southern States, its normal habitat, but the evidence at hand 115 indicates a second seasonal generation, and this is possible since adultPhyllophaga of one species or another are active in the Southern Statesfrom the latter part of March until the middle of August. The species may prove to be an appreciable aid in the control ofPhyllophaga in the Southern Fig. 43. Biomyia Uichnosternae Towns., male Sakcophagids, ixcludixg Doubtfcl RecokdsSeveral sarcophagids have been recorded in literature as parasiticon Phyllophaga adults, and we have occasionally reared them—andonce an anthomyiid—in cages containing May-beetles, but in most casesit was plainly evident that the flies had hatched from maggots which fedonly on the dead beetles. In all cases where these flies have been rearedat the Lafayette Laboratory, the cages were covered with wire-screen,permitting larvae or eggs to be thrust into the cage through the , all such rearing records were from cages containing largenumbers of beetles confined for parasites, and the dead beetles andabundant excrement were no doubt attractive to the scavenger might be noted that the sarcophagid larvae invariably left the dead 116 beetles to pupate, which is never the case with the beetle parasites alreadytreated.
