Several preliminary experiments were conducted to examine factors influencing the daily feeding rhythm and the yearly developmental sequence of the larval stage of the firefly Photuris pennsylvanica. Loose, loamy, well-drained soil allowed normal circadian behavior while sand, sawdust, and clay-like mud prevented larval migration. The yearly developmental sequence could be duplicated in the laboratory by simulating environmental conditions, and acceleration of this sequence was achieved by manipulating the length of exposure to simulated winter temperature.
