When strong light is thrown upon it it crawls away or takes wing quickly and when found must be caught instantly if at all. The larvae and adults live upon decaying vegetable and animal matter. The larvae of this species and other larvae were brought into the laboratory in pieces of bait which had been in the cave.

The larvae of this species and other larvae were brought into the laboratory in pieces of bait which had been in the cave. The larvae were not distinguished from others, but the pupae were identified and two drawings made (figs. 4 and 5). This species has been recorded from Wyandotte Cave, and I have taken it in Twin Cave and Mayfield's. Aphiochaeta (Phora) rufipes Meigen. MEIGEN, System. Beschre., vi, 216 (Europe and North America). ALDRICH, Cat. N. A. Dip., 1905, 337. Two specimens, probably belonging to this species, were taken at the first bend in bright twilight. It is possibly not uncommon in Mayfield's Cave, and others of this species may have been mistaken for nigriceps. It has been recorded from Mammoth Cave (Call, 1897, 386), and I have it from Twin Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Carnegie Institution of Washington.
