Family BOMBYLIIDAE. 



The "Bee-flies" vary in size, some being small, others rather large and are usually or- 

 namented with spreading whitish or yellowish hairs, making them resemble bees. They feed 

 on flowers and often are seen resting along sunny paths through woods. The larvae are para- 

 sitic on the caterpillars of moths and the eggs of grasshoppers. In the nests of bees they de- 

 stroy the yoiuig larvae and the food supply.
