What is the typical wingspan range for the adult Greater Wax Moth (Galleria mellonella)?
Answer
30 to 40 millimeters
The adult stage of the Greater Wax Moth, *Galleria mellonella*, is characterized by a specific size range for its wingspan. Most reliable observations place this measurement consistently between 30 millimeters and 40 millimeters. More precisely, certain measurements narrow this down to a range spanning from 30 mm up to 37 mm. When converting this size to imperial units, it corresponds roughly to 1.25 to 1.5 inches. This larger size is a key differentiator when beekeepers encounter wax moths and need to confirm if they are dealing with the more destructive Greater Wax Moth versus its smaller counterpart, the Lesser Wax Moth.
