Photinus marginella is our only pale firefly in Ontario. This one is especially light - just hatched. When older, the colour will darken somewhat to a light greenish-brown with a golden border.
This is the Black Firefly. It was found flying around the football field at the high school. Black Fireflies are most commonly found in Central and North America. Also, Black Fireflies are easily identified by having a black body, a black and orange head, and 2 long, black antennae.
Lampyridae is a family of insects in the beetle order Coleoptera. They are winged beetles, and commonly called fireflies or lightning bugs for their conspicuous crepuscular use of bioluminescence to attract mates or prey. Fireflies produce a "cold light", with no infrared or ultraviolet frequencies. This chemically produced light from the lower abdomen may be yellow, green, or pale red, with wavelengths from 510 to 670 nanometers.
