Subject: Giant Wood Moth?
Geographic location of the bug: Black Rock, Melbourne
Time: 04:32 AM EDT
Your letter to the bugman: I think these are Endoxyla cinereus, and I assume they are mating? Some students of mine found these in the school playground – absolutely fascinated. The CSIRO page still doesn’t show it as present in Victoria, so perhaps it is something else?

We agree that these are mating Wood Moths in the family Cossidae, but we cannot confirm the exact species with any certainty. We often have trouble differentiating members of this family, and we also confuse members of this family with the Ghost Moths or Swift Moths in the family Hepialidae, which are pictured on Butterfly House. While we would not rule out that this might be Endoxyla cinereus, which is pictured on Butterfly House, we can state that it really resembles the individual we posted earlier today that we believe is a Wattle Goat Moth, Endoxyla encalypti.
