Description

For a key to the terms used, see Glossary of entomology terms.

A. atergatis Westw. (55 f) has two rather different seasonal forms. In both forms the wings above are bright uniform orange-yellow to the base, beneath in the dry-season form lighter and in the rainy-season form somewhat darker and more reddish than above; the black dots are arranged as in oncaea, but in the rainy-season form very large and thick; the forewing above is only narrowly black at the costal and distal margins, but without apical spot, and has strong black streaks in 3 to 6; the hindwing is a little blackened at the base of cellule 1 c and the cell; the seasonal forms differ particularly in the development of the marginal band of the hindwing; in the rainy-season form the black marginal band is on both surfaces about 1 mm. in breadth, above unspotted, beneath with narrow streak-like white marginal spots; in the dry-season form the marginal band is entirely absent or is only weakly indicated beneath, hence the marginal streaks of the under surface shade into the ground-colour without any dividing-line; the under surface of the hindwing has more or less distinct red spots. Angola; southern Congo region and Rhodesia. ^[4]

Biology

The habitat consists of open areas in deciduous woodland.

Adults are on wing year round. There are distinct seasonal forms.
