Malacosoma disstria
The Forest Tent Caterpillar Moth is a fluffy, brown moth that loves to fly around in the woods. It starts its life as a caterpillar, munching on leaves before transforming into a beautiful moth!
Habitat: Forests
The Forest Tent Caterpillar Moth is typically dull yellowish-tan to brownish, often with a darker diagonal band across its forewings. Males are usually smaller and darker than females. Unlike many other moths, its wings lack prominent spots or complex patterns, making it appear quite plain.

Forest Tent Caterpillar Moth can blend seamlessly with tree bark because of its mottled brown and gray wings that mimic its surroundings.
The moth can find mates in the dark because females release powerful chemical signals called pheromones that males detect from afar.
Females can protect their future offspring by laying eggs in a durable, waterproof mass covered with a protective cement-like substance.
Its eggs can survive freezing winters because they are laid in a tough, insulated case on tree branches, waiting to hatch in spring.
