They get a slightly bad rap since occasionally the larvae eat earthworms too. Their favorite foods are snails, slugs, worms, and grubs which they capture by injecting a digestive enzyme to paralyze them. Called Glowworms because they too are bioluminescent, these larvae can live for up to two years in this form. With six legs and overlapping plated bodies, the young larvae are predatory and forage through leaves, the soil, and rotting logs for food. This is the larval stage of the Adult Beetles. The tiny glowing eggs hatch and out emerge flattened millipede-looking insects. Lighting bugs mate and lay their eggs in the canopy of native pine trees and in leaf litter. Every Firefly species has its own patterns of flashes and blinks. The female’s flash acts like a beacon and the flying male's twinkle in return. If you see a flying Lightning Bug at night - then it is a male, the females stay closer to the ground for protection and blink from there. The blinking starts around the end of June and continues through August in most parts of the United States, but the adult beetles are emerging in spring and still flying around until fall. These glowing chemicals are being studied to treat disease, are being used in equipment that’s detecting life in outer space, and are even tested for helping stop food spoilage and bacterial contamination. It is believed the flashing, which can range from vivid yellow, and yellowish-orange, to green and yellowish-green, is created by controlling how much oxygen goes to this special organ. Combining chemicals called luciferin, enzymes called luciferases, and oxygen with ATP (in the cells of every living organism) they create 'cold' light. If the pair's blinking syncs up, they are a match! They are able to blink because of a special organ in their abdomens. Some species of Firefly larvae are aquatic and have gills, others live entirely in treesīoth males and females blink, using a type of bug Morse Code. There is a cannibalistic predatory Firefly that mimics other Firefly species to eat themĬan ‘reflex bleed’ a nasty tasting substance if a bird or lizard tries to eat them The adult abdomens, the larvae, and even their eggs glow in the darkįound on nearly every continent - anywhere it is temperate and moist Produce cold light without producing heat - 100% of the energy becomes light These creatures do not bite, do not carry any disease or poisons, help pollinate to some extent and bring a touch of magic to the garden and to the imaginations of young and old alike! Other species can have orange and black wing covers (called elytra), or look more yellow and black and a few look red. These are actual beetles and can haveīlack wing covers, solid orange, or orange and black striped heads. Of the 2,000 species of Fireflies in the world, there are about 165 species found in North America. How would you like to be a part of keeping these blips of light returning to your garden every year? Read on to find out how to keep the magic alive for generations to come! Then your Mom may have let them free outside as soon as you fell asleep.īut unless you live on the outskirts of town or in a very rural area, you may not see as many Fireflies as you did back then, quickly becoming a rarity in the night sky. You may have added a few sticks and a pinch of grass to ‘make it feel just like their home’ and set them onto your nightstand for the night to watch them blink. Whether you call them Lightning Bugs, Fireflies, or Lightning Beetles, you have no doubt spent many a hot, summer evening chasing them with a net around the backyard and keeping them in a jar with holes punched in the lid.
