An information board in the bug exhibit will provide information about this bug.

"Both male and female fireflies are capable of producing light from their lower abdomens. This light isn't the same as the light from a lightbulb, though, and isn't hot when you touch it. Fireflies can actually glow when in the egg and larval stages, but that light is comparatively weaker."

In real life[]


The Firefly, or Lightning Bug, are winged beetles named so for their conspicuous crepuscular use of bioluminescence to attract mates or prey. They 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. They are found in temperate and tropical environments. Many are in marshes or in wet, wooded areas where their larvae have abundant sources of food. These larvae emit light and are often called “glow worms”, in particular, in Eurasia.

Fireflies tend to be brown and soft-bodied, often with the elytra more leathery than in other beetles. Though the females of some species are similar in appearance to males, larviform females are found in many other firefly species. In many species, both male and female fireflies have the ability to fly, but in some species, females are flightless.
