Lampyridae
Lampyridae (glow-worms, fireflies, lightning beetles; subclass Pterygota, order Coleoptera) Family of beetles in which the male
elytra are soft and
pubescent, and the eyes large. Females resemble larvae; the body is elongate, often without wings or elytra, and the eyes small. The antennae are
filiform. Larvae are tawny, the body segments are expanded, the head is small and concealed, the
mandibles are large. They feed on slugs and snails, which they inject with digestive juices. All stages are luminous, but this is most pronounced in adults; light is produced from the end of the abdomen to signal a mate (compare
ELATERIDAE). There are 1700 species.
