Lightning Bug larvae live on the ground, under bark, and in moist swampy places. They eat earthworms, snails and slugs, plus they may scavenge certain small dead animals and other organic material . They have been seen following slime trails to their slug and snail victims. Lightning Bug larvae, one of which is shown at the right, have sickle-shaped mandibles with which they can inject a kind of chemical that paralyzes their prey and helps digest it. Several larvae have been seen attacking large prey together.
