Trichiosoma lanuginosum

Trichiosoma lanuginosum is a species of sawfly in the family Cimbicidae, a group of large, robust hymenopterans often mistaken for wasps. The genus Trichiosoma includes species associated with various deciduous trees, where larvae feed on foliage. Adults are typically encountered in spring and early summer. This species belongs to a family whose larvae are caterpillar-like herbivores, distinct from the carnivorous or parasitoid habits of many other Hymenoptera.
