    Big Dipper Firefly - (Photinus pyralis)

    The gentle, harmless Big Dipper Firefly brings delight to the onlookers of the night sky - and a smile to the child in all of us.


    Staff Writer (8/15/2017): Fireflies are famous for their nighttime displays in the summer. These friendly beetles delight children and adults alike with their bioluminescence. The yellow-green glow comes from their abdomen. Chemical reactions inside the firefly create visible light without generating any heat. The intensity of the light and the frequency that it flashes is controlled by the firefly's nervous system.

    Capturing fireflies in jars to keep them stresses them terribly and eventually kills them. This insect should be admired and handled delicately, but ALWAYS release them back into nature.

    This particular species of firefly will flash its brightest light and then flies upward in a "j" curve as the light diminishes. They can be found in open fields, meadows, parks, gardens, front yards and backyards.

    Larvae feed on earthworms, slugs and snails, but adults are not known to eat at all.
