Stettner’s Silk Moth Copiopteryx Semiramis

A recent trip to Costa Rica turned up Copiopteryx semiramis, a large silk moth along the lines of our cecropia and luna moths.  This species has no common name, so there is a move to name the species “Stettner’s silk moth”.

Stettner’s silk moth, Copiopteryx semiramis is a member of the subfamily Saturniinae. It typically has a wingspan of about 10 centimeters. Its patterned brown wings act as camouflage to evade predators. It is found mainly in the rain forests of South America

There is a long history of naming species after naturalists that are held in high esteem by the community. Craig Stettner (1963 – 2018) was a much-admired faculty member at Harper College in Palatine, Illinois where the College has also dedicated the Craig Stettner Prairie on its property.

Craig ran a popular study abroad program in Costa Rica, providing students with life changes experiences personally and academically. His commitment to conservation and passion for the environment was inspiring.
