Moths rely heavily on their colorful and patterned wings to attract the right mate. After finding a suitor, the moth mate and proceed to lay eggs. Thus, ensuring that its heritage lives on. Though the research for this is not adequate, many believe that the scales on the moths help them escape a sticky situation. For instance, getting caught up in a spider web. By shedding their scales, they can slip out of the hold and fly off to live another day.
The tiny hairs also function as moisture repellent by keeping the drops apart. The structure is so small that the water tension is sufficient to avoid the drops of getting in contact with the true surface like a nail board. This keeps the moths dry and reduces their wait so they can continue flying. The hairs do also have an astonishing effect during rain.
They break up the raindrops on impact and let them explode in all directions — keeping the wing safe. So, the scales on a moth serve several functions that are all necessary for them. However, research has shown that the scales have little to no effect on their flight capabilities. So, even if they lose a significant portion of their scales, they will not become incapable of flight. Nor do they feel pain when losing the scales. However, the dust or scales play a vital role in continuing the species by attracting mates.
Without it, the moths will either have to alter their method of mating or face possible extinction. Plus, without scales, a moth is far more likely to be eaten by frogs, bats, birds, etc.
Because they will have no way to hide or scare off their predators. So, the moths are not physically hurt when losing their scales nor does it affect their flying. But losing scales will hinder some important biological functions that are important for the species as a whole. Despite the massive importance these scales have, moths are constantly losing them for various reasons. Even a strong gust is enough to scatter some of the scales in the air.
This is why some people can have certain allergic reactions to touching a moth or even being around them. The scales can get into their lungs or attach themselves to the skin of people. Their wings are covered in tiny scales, overlapping like shingles on a roof. These scales give the butterflies and moths their wing patterns, and make them more aerodynamic, a little like feathers on a bird's wing. However, unlike birds, when butterflies and moths lose scales on their wings, they can still fly.
Depending on the amount of scales lost, it may make them less aerodynamic and affect their flight pattern slightly, but it will not kill them. Some species of butterflies and moths actually have very few scales, resulting in partially or entirely clear wings. It's really not much different than most other insects with wings, such as dragonflies and wasps.
Butterflies and moths naturally lose scales throughout their lives. They often rub some off in the course of emerging from their pupa, in addition to losing scales while flying, and from escaping from birds or other animals nothing like a mouthful of powdery scales to make you change your mind about a meal! Although butterflies and moths are certainly delicate, they are much hardier than many people give them credit for. So the next time you encounter a butterfly or moth, don't be afraid to coax it onto your hand if it wishes to cooperate!
Handle it gently, don't try to pet it, and enjoy its beauty! Because a moth is most active at night, he need a little help to stay warm while the sun's down. The scales provide an insulating layer to help the moth stay warm. A butterfly uses scales for thermoregulation as well, but a moth tends to have thicker scale layers.
Without the ability to heat up in the sun's rays, a moth needs extra insulation. Even though his colors are dull, a moth needs the right combination of colors and patterns to attract a mate. Male and female moths follow pheromone trails to help them find mates, but the visual cues are key when they get close enough to spot each other. When many scales are missing, the moth can still fly but he might not be able to attract a mate.
Earthworms are safe and fun to touch, as this Discovery Garden visitor proves. Photo by Lee Patrick. Centipedes can bite, but they are nearly impossible to catch, which works out well. Though centipedes do technically have poisonous fangs, most common northeast species are far too small to be threatening to humans. Photo by Joseph Berger, bugwood. The "urticating" hairs on stinging caterpillars are named after this plant, European stinging nettle, or Urtica dioica ssp.
Wineberries, wild raspberries, and other weedy berries can be mistaken for poison ivy, but they feature tell-tale thorny stems. Their leaves are generally serrated all the way around the edges, whereas poison ivy has defined notches toward the upper half of the leaf. Poison ivy climbing a tree, in beautiful fall color. On the positive side, poison ivy berries are an important food source for wildlife. Lots of plants appear to have poison ivy's "leaves of three," such as wild sarsaparilla Aralia nudicalis shown here.
If you look closely, you'll see there are no tell-tale notches on the leaf's edges, and that each compound leaf actually contains five leaflets. Photo by Ashley Gamell,.

Discussion Lisa Craft July 1, I believe the photo above is mislabeled and is not a tomato hornworm Manduca quinquemaculata but a tobacco hornworm Manduca sexta.

Hickory Tussock Moth Caterpillar Avoid touching the delightfully fuzzy hickory tussock moth caterpillar, Lophocampa caryae , at all costs. Poison Ivy Poison ivy Toxicodendron radicans always has three leaflets, but those leaflets may be shiny or dull and may be pale or dark green.
