Poplar Admiral (10)
|The Poplar Admiral (Limenitis populi) is a butterfly in the heliconiine clade of the Nymphalidae family.|
The wingspan in spread specimens varies for the males from 66 to 77 mm, and for the females from 82 to 85 mm, all mesures done on the larger private collection of Limenitis populi, now in the hands of Jean-Claude Weiss, the well-known specialist of Parnassius. In fact the specimens in the field are relatively of the same size, the difference in mesures are mainly because some sub-species are larger or smaller than other ones, it does not mean the size of this species is so variable in one location. It exists some specimens very small, about half size, but they are issued from breedings. So it is a noticeable difference in size between genders. The females have distinct broad white lines over their back wings. On the males the lines are narrower and fainter, and sometimes are not there at all. The upper surface is dark brown with white spots. The white stripe is surrounded by orange and blue borders. The underside is orange.
