¹ The most suitable diet appears to be sliced apple, with water available for drinking. Apple is preferable to banana, which is apt to entangle the legs. Pyretophorus costalis if left undisturbed in the dark thrives well enough in captivity, and feeds freely on human blood if opportunity is afforded; females in captivity occasionally deposited eggs in the drinking throughs, and the eggs hatched out in about forty hours at laboratory temperature in April. The food which suited the larvae best appeared to be dry lean meat, pulverised.
