"A significant white spot on the head is, according to the Covell Field Guide, a characteristic mark of Desmia maculalis. Brian Scholtens informs me that this is not a reliable character and that two species (D. maculalis and D. funeralis) cannot be distinguished in typical dorsal view photos. It would be necessary to see mouth parts at high magnification or examine genitalia to make specific determinations. It is best to consider photos of these species as representing a species group." ~ Bob Patterson.
