    Ailanthus Webworm Moth - (Atteva punctella)

    The skinny, orange Ailanthus Webworm Moth may look more like a beetle, especially since it is at home on flowers of its namesake.




    Staff Writer (1/26/2017): The definitive coloring and stripes on this moth make it unique among Webworm Moths. They tuck and roll their wings close to their bodies when resting, as opposed to spreading them out or letting them lay flat against themselves. They are very thin as well, so they might look more like a flower beetle than a moth.

    They are members of the Bagworm moth family. This refers to the cocoon 'bags' that the caterpillar spins and carries with it. The cocoon gets covered in bits of leaves and sticks and other plant debris. When it is time for the caterpillar to pupate, it attaches the cocoon to a branch on a tree or shrub and enters it to complete the next part of its life cycle.

    Adults are active in the daytime and can be seen from spring through autumn. They are considered good pollinators. A variety of plants and shrubs are food for the caterpillar. This moth gets its name from the Ailanthus tree, where its larvae make webs on leaves. The grayish caterpillars particularly like to feed on the foliage of this tree.

    Once a female lays her eggs in her old cocoon to protect them, she dies. Only one generation of moths lives every year. The eggs overwinter in their case and emerge as caterpillars in the spring.
