Jenny McKenzie (author), Southwestern University, Stephanie Fabritius (editor), Southwestern University. Otherwise, they spend their larval stage underground, where they can find another food source of other insect larvae. After their second winter they … There is no known negative economic importance for humans. The light-producing organs differ between sexes. The light organ (specifically the photogenic layer) is supplied with numerous tracheal branches, which are thought to provide the required oxygen for light production. Croton. NCBI Photinus pyralis Annotation Release 100. Females wait on the ground for passing males to flash their signal, and then answer with their own specific signal. Vegetation is made up mostly of grasses, the height and species diversity of which depend largely on the amount of moisture available.
Dissection is required for confident species identifications. Firefly larvae spend winter and early spring burrowed into the soil. This dating game occurs in summer and early fall, and the female generally lays about 500 eggs on damp soil during this time of year. After passing through the larval stage, the developing firefly moves into chambers in the moist soil and pupates. "Photinus pyralis" (On-line), Animal Diversity Web.
