Moths are dusty because of their scales. Scales are what give a moth its coloration and patterning. Moths, like butterflies, have scales on their forewings, hindwings, body, and antennae.
These scales are made out of chitin, the same material that makes up insect exoskeletons. Moth scales are usually brightly colored or patterned for camouflage and mating purposes.
Moths also have a ton of hair-like structures called setae (or sensilla) on their bodies that help them detect smells and touch.
Do moths create dust?
Moths don’t usually create dust. The way they fly and lose scales on their wings creates an illusion that it is the moth that is generating the dust when in fact, it is more like they are shedding.
Moths have scales all over their bodies, and just like feathers on a bird, they can break off and become airborne.
The amount of dust you see from a moth depends on how often the moths fly and also how long they’ve been flying. If a moth has been sitting in one spot for a while, then it will not be able to shed as much dust as when it flies around.

Why do moths turn into dust when killed?
In its simplest form, dust is a collection of particles. The only reason we see it as something different is that there is so much of it. For example, the dust that collects underneath your bed is just a collection of skin cells and hair, but the sheer amount of them gives it the appearance of dust.
One way in which dust is created is as protection through camouflage, distracting predators, and getting dirt on their prey. This is similar to how human corpses turn to ash once cremated. Ultimately, everything turns to dust when it’s killed.
Is the powder on moth wings poisonous?
The powder on moth wings is not poisonous. The powder is actually a chemical that comes from the scales on their wings.
However, there are some moths that are poisonous, but not in the sense that they are going to poison you. The Gypsy Moth, for example, produces a caterpillar that can be allergic to humans.
Scientists still aren’t really sure why moths have scales or how the scales get their colors, but we do know that there are a lot of these scales. Up to 250,000 each moth! Moths may look plain and boring from far away, but up close, they sure are beautiful—and yes, quite dusty.
