fireflies

(Family Lampyridae)

               
Overview

Lampyridae is the family that includes fireflies, also called glow worms or lightning bugs. There are about 2,200 described species worldwide, about 170 species in North America north of Mexico, and at least 19 species in Minnesota.

Most adults and all larvae produce light by an efficient chemical process that gives off almost no heat. In most species, flashing is the means by which the male, flashing in flight, finds a female of the same species, flashing on the ground.

Larvae prey on small insects, insect larvae, snails, and slugs. Adults of most species do not feed.

Identification

Adults are soft-bodied, elongated, and flattened. Most are brown or black with light markings. They have nearly parallel sides and rounded ends. The exoskeletal plate covering the thorax (pronotum) is nearly as wide at the base as the forewings (elytra). The front of the pronotum is extended forward and completely covers the head, though the head may be extended beyond it. The elytra are leathery and loosely cover the body. The last 2 or 3 abdominal segments are often luminescent. The last part of the leg (tarsus), corresponding to the foot, has 5 segments.

About

Sep 4, 2016

Each year in late spring the Great Smoky Mountains National Park hosts a special light show, thanks to a species of beetle native to the region. These are the synchronous fireflies, known for coordinating their flashes into bursts that ripple through a group of the insects. As with other fireflies, their yellowish glow helps potential mates find one another.
