This is one of the many reasons to keep leaf litter in our garden beds. Larva – Larvae emerge from their eggs in late summer, and live in the soil through the winter before pupating in the spring. These eggs usually hatch in three- to four-weeks. Fireflies prefer moist soils, and will lay eggs under mulch or leaf litter, where the soil is likely to stay moist.

Like all beetles, fireflies undergo complete metamorphosis with four stages in their life cycle: egg, larva, pupa, and adult.Įgg – In mid-summer, mated females will deposit about 100 spherical eggs, singly or in clusters. I can’t believe I’m about to say this, but a study shows, size matter! Females are more likely to mate with males who give them a larger nuptial gift. The flash of a male firefly is only the first stage of courtship, and may not even be the most important. Males flash to attract females, and mating begins when the flash carries the right rhythm. It has been noted flashes of synchronous fireflies get out of synch for a few minutes after a car’s headlights pass. Light from buildings and streetlights make it difficult for fireflies to signal each other during mating season-meaning fewer fireflies. The reasons are still to be pinpointed but experts believe habitat loss and light pollution play a role by interfering with firefly flash patterns. Instead, on the East coast at least, they remain in moist leaf litter and flash to a receptive mate. Another interesting fact about fireflies is most females don’t fly. Fireflies in the western United States, for example, lack the ability to produce light. Did you know there are fireflies out West as well, but they don’t light up the sky at night? Despite their name, not all fireflies glow. Livestock owners need to beware that blister beetles can be inadvertently baled in hay.There are more than 2,000 species of fireflies, a type of beetle. Keep cats indoors, and watch what Fido gets into. Remember that inquisitive cats, dogs, and other pets can also suffer from encounters with toxic insects, millipedes, and other invertebrates. Most millipedes coil up before excreting such chemicals. Among the over 30 toxins known from various millipedes are hydrogen cyanide, acetic acid (vinegar), formic acid, benzaldehyde, and phenol. Most millipedes, class Diplopoda, have defensive chemical secretions that they deploy when threatened by a potential predator. Two chemicals stored in separate glands inside the beetle come together in a “reaction chamber” in the beetle’s rear, creating a minor explosion. Bother a bombardier beetle and it will literally blast you with hot acid.

Bombardier Beetlesīombardier beetles (Brachinus spp.) are not common, but you might find them under stones or boards in fields or near water. This is the bug’s way of advertising that it is dangerous to eat. Steer clear of insects with bold patterns of black or metallic blue and white, red, yellow, or orange. Insects that feed on toxic plants, like milkweed, often sequester those toxins, incorporating the poisons into their own bodies for self-defense. Ingested, it can be fatal, even to horses and other large animals. The liquid contains the toxin cantharidin, and it can raise painful, scarring blisters on sensitive skin. Squeeze one and it exudes an oily liquid from its leg and body joints. They are most abundant in deserts, prairies, meadows, and agricultural lands. Blister Beetlesīlister beetles (family Meloidae) are unfortunately non-descript, and diverse in their appearance. You wouldn’t lick a toad, so don’t try a firefly, either.

The bright glow of a firefly adult or larva is thought to be a warning that these insects are full of potent steroid chemicals called “lucibufagins.” The compounds are a close relative of toad toxins. If your toddler is prone to putting things into his or her mouth, be careful that they don’t try tasting these toxic insects and related organisms.
