Comment: Ossiannilssonola can be a very challenging genus to identify species that are not distinctive. A number of species are visually identical. These species are: danae, clymene, hermione, troza, mcateei, and bangsoni, none of which have been reported from North Carolina. In these species, adults are whitish to yellowish-white with three brown to black dots of even intensity (similar size) anterior to the apical crossveins in the inner three basal cells. The dorsum of the abdomen is pale or whitish. Some individuals though of O. australis can also have whitish wings with brown apical spots, but the abdomen is black dorsally, with the outer margin of each segment yellow. A good view of the abdomen is therefore necessary for determining if an individual may be O. australis (this view is typically possible with a nice macro photo, as the black tends to be visible through the wings). (Christian, 1953)
Additionally, see the comments section of O. berenice for info on species with yellowish wings and apical wing spots that are difficult to distinguish from one another. |
