Spiegelaus

Spiegelaus is a genus of moths in the family Geometridae. The genus was erected by Charles Oberthür in 1908. Spiegelaus moths are typically found in Asia. They are characterized by their wing patterns, which often resemble dried leaves or bark, providing camouflage against predators.

The larval stage of Spiegelaus moths, like other geometrids, often exhibits a "measuring worm" or "inchworm" locomotion. This is because the larvae have only two pairs of abdominal prolegs, in addition to the thoracic legs, giving them the appearance of measuring the ground with their bodies. The diet of these larvae can vary, but they often feed on the leaves of specific host plants.

Adult Spiegelaus moths are generally nocturnal or crepuscular. Their feeding habits as adults are less pronounced, as many species do not feed at all or subsist on nectar. The primary purpose of the adult moth is reproduction. The lifecycle involves egg, larva, pupa, and adult stages. Information on the specific species within the Spiegelaus genus, their exact geographical distribution, and detailed life cycle information can be found in entomological literature and specialized databases.
