Description from Seitz
A. angarensis Ersch. (67h). About the same size as the previous [A. iphigenia Graes] ; the forewing less elongate. The underside of the hindwing bears a very close resemblance to that of A. selenis sibirica, but the costal spot of the median band is essentially different in shape, as shown in the figure. Moreover, angarensis has a row of silvery marginal spots, which are absent in sibirica or only indicated. The female larger and paler. — In Amurland, in June, locally very common.

Biology
The larva feeds on Vaccinium.
