Tolype Moth (Tolype velleda)

The tolype moth, also known as the large tolype moth or the velleda lappet moth, is a member of the lappet moth family. They are recognizable by their fuzzy white fur, which increases their visibility. Naturalist and entomologist Casper Stoll first described this moth in 1791.
