Description

''A. zetes'' is a common species in Africa, distributed from Sierra Leone to Natal and Abyssinia; it develops several races and forms and is darkest in the north-west, gradually becoming lighter and lighter towards the south and east. Forewing with 2 black spots in the cell, one at its apex, large elongate discal dots in 3 to 6 and 10, rounded free discal dots in 1b and 2 and at least beneath with large yellow marginal spots in 1b to 6. Hindwing in addition to the confluent basal dots with a median dot and distinct discal dots, of which the one in 2 is placed close to the base of the cellule and that in 4 further distad than the rest; the black marginal band broad on both surfaces or at least beneath with light spots.
* ''zetes'' L. Forewing above dark blackish, unicolorous or beyond discal dots 3 to 6 a little lighter; discal dots little distinct on the dark ground. Hindwing above black to the apex of the cell, then with orange-red median band 5 to 6 mm. in breadth, in which only discal dots 3 to 5 are placed free, beneath with whitish ground colour and reddish spots in the basal area and on the marginal band. Sierra Leone to the Cameroons; transitions to ''menippe''.
* ''menippe'' Drury (54 b). Forewing above with distinct red-yellow marginal spots and usually also with larger or smaller red-yellow spots in lb, 2 and the cell and with small whitish subapical band in 4 to 6; the red-yellow transverse band on the upperside of the hindwing 10 to 12 mm. in breadth. The female is larger and has the ground-colour black-grey on the forewing, grey-yellowish on the hindwing. Throughout West Africa to Angola and Uganda.
* ''jalema'' Godt. is an intermediate form between ''menippe'' and ''acara'' now ''Acraea acara'' ">Acraea_acara.html" ;"title="now ''Acraea acara">now ''Acraea acara'' and has the forewing above black at the base to vein 2 and then a red-yellow transverse band about 12 to 13 mm. in breadth, which extends from the inner margin to the anterior margin of the cell, covers the base of cellules 2 and 3 and encloses 4 black spots (one in the cell, the median spot and discal dots 1b and 2); subapical band, as in menippe, short and narrow. Cameroons to Rhodesia.
* ''acara'' Hew. (54 b, c) [ now species ''Acraea acara'' ] is the South and East African race and only differs from ''jalema'' in having the red-yellow colour on the upper surface even more extended and particularly in the fore wing having a large red-yellow subapical band about 7 mm. in breadth in 4 to 6; forewing at the apex black for a breadth of about 6 mm. Natal to Rhodesia, Nyassaland and British East Africa
* ab. ''mhondana'' Suff. ''Acraea acara'' Discal spots 4 to 6 of the forewing united with the black spot at the end of the cell. Among ''acara''. ab. ''caffra'' Fldr. ''Acraea acara'' (= ''tescea'' Suff. ''Acraea acara'' only differs from ''acara'' in having the upperside of the hindwing whitish in the middle. Natal; Transvaal.
* f. ''barberi'' Trim. ''Acraea barberi'' ">Acraea__barberi.html" ;"title="''Acraea barberi">''Acraea barberi'' differs from ''acara'' in the forewing above having at the apex a marginal band only 2 mm. in breadth; the black lunulate submarginal line on the upperside of the forewing is sometimes strongly developed, sometimes entirely absent, ab. ''trimeni'' Auriv. [ ''Acraea barberi'' ] Transvaal and Griqualand.
* ''sidamona'' Rothsch. and Jord. is similar to ''acara'' only differing in having the basal dots in the cell and in 1 b of the forewing free and the marginal dots on the underside of the forewing in 1b to 5 all completely bordered with black proximally. Abyssinia.
* The larva of ''zetes'' is orange-yellow with a dark red transverse band dorsally on each segment; head glossy red; spines black; lives in Natal on ''Passiflora''. Pupa reddish white with black markings.
