Limnephilidae
Northern Caddisflies are small insects that live near water. They build cozy little homes from twigs and pebbles, which they carry around as they swim and float.
生息地: Wetlands
The Northern Caddisflies has a moth-like body with four hairy wings that fold back tent-like over its abdomen. They are typically dull brown, grey, or black, providing camouflage against bark or vegetation. Their long, slender antennae extend forward, distinguishing them from true moths at rest.
