Firefly or Lightning Bug
Photinus pyralis
Photinus pyralis
The Pyralis firefly (also known as the lightning bug)
is a common firefly in North America. This partly nocturnal, luminescent beetle
is the most common firefly in the USA.
At night, the very end (the last abdominal segment) of
the firefly glows a bright yellow-green color. The firefly can control this
glowing effect. The brightness of a single firefly is 1/40 of a candle.
Fireflies use their glow to attract other fireflies. Males flash about every
five seconds; females flash about every two seconds. This firefly is harvested
by the biochemical industry for the organic compunds luciferin (which is the
chemical the firefly uses for its bioluminescence).
This flying insect is about 0.75 inch (2 cm) long. It
is mostly black, with two red spots on the head cover; the wing covers and head
covers are lined in yellow. Like all insects, it has a hard exoskeleton, six
jointed legs, two antennae, compound eyes, and a body divided into three parts
(the head, thorax, and abdomen).
Both the adults and the larvae are carnivores. They eat other insects
(including other fireflies), insect larvae, and snails.
