![]() This disorients echolocation of bats, one of their main predators. They protect themselves by spinning their flowing tendril-like wingtips in circles in an effort to escape predators. The wingspan of adult Luna Moths can be anywhere from 3 to 7 inches across, making them one of the largest moths in North America. After mating or laying eggs, the adult Luna Moths will die. Male antennae are much fluffier which helps them detect pheromones or chemical trails released by females even from great distances. As Luna Moths are nocturnal and mate after midnight, they rely on their fluffy antennae to find mates. Male and female Luna Moths look almost the same, except for their antennae. They live off of energy stored during the pupal stage. They do not eat in the adult phase as they lack a mouth (proboscis) and digestive system. The adult Luna Moth lives for an average of 1 week with a sole purpose of procreation. The leaf camouflages the cocoon among debris on the ground.Īfter about 3 weeks, the adult moth emerges in the morning, spending the remainder of the day drying its wings until it can fly. Afterwards the Luna Moth crawls to the ground where it will create a cocoon by weaving a dry leaf around itself in a silk coating. The eggs hatch into caterpillars in about 1 week and will remain in this stage for about 1 month.ĭuring this time, the caterpillar will eat almost constantly from the leaves of trees where they are born like walnut, birch, sweet gum, persimmon, sumac, and hickory all of which are found in New Jersey. The female lays up to 200 eggs on the underside of leaves. Like butterflies, Luna Moths undergo complete metamorphosis with a four-stage life cycle of egg, larva (caterpillar), pupa (cocoon), imago (adult). Luna moths are native to forested areas of North America (East of the Rockies) and can be seen in late spring and summer here in New Jersey. The stunning Luna Moth is worth a closer look. The diurnal moth species pollinate during the day. Along with bats, moths are one of the few pollinators that cover the night shift. As most moths are active in the dark, they are especially integral to nighttime pollination. If the population of moths changes or declines, this can indicate that there is a larger problem in the ecosystem that should be addressed. Moths are considered an indicator species because they can be used to determine the health of habitats. Moths are important to our ecosystem as a valuable source of food for other creatures like bats and birds. Also look at their antennae a moth’s antennae are serrated or feathered, while a butterfly’s antennae are long, thin and always clubbed at the end. When butterflies land they close their wings together, but when moths land, they spread their wings apart. ![]() It is hard to tell the difference between moths and butterflies because they have so many similarities. Unfortunately, the overuse of artificial light interferes with moth mating and navigation. Moths keep the moon at a certain position in relation to their body to guide them. This is similar to the way we use the north star as a directional guide. ![]() Just like we learned with lightning bugs, light pollution confuses moths and interrupts their instinctual reliance on the moon to navigate-a process called transverse orientation. Moths are sensitive to certain wavelengths of light, especially ultraviolet light, or white light, and are less attracted to yellow light as it falls towards the other end of the color spectrum. This is a phenomenon known as positive phototaxis- a natural bodily movement in response to light. If you’ve ever left an outside light on at night in the summer, you’ve probably noticed that moths and other insects are drawn towards the bright glow. ![]()
