[ редактировать ]
Размах крыльев составляет 45–55 мм для мужчин и 53–60 мм для женщин. Мужчины и женщины оба показывают одинаковый диапазон окраски. [ 2 ] Сумеречная Acraea является переменным видом, но наиболее распространенной формой является черная с белой полосой через передние крылья и белое пятно на нижнем переднем крыле и на задних крылах. [ 2 ] Есть несколько описанных морфов (с белыми, желтыми или оранжевыми пятнами), включая:
- фон высокий
- фон исполнение
- фон Протея (черная с кремово-желтыми пятнами)
- фон Monteironis (черный с белыми пятнами)

[ редактировать ]Многочисленные формы А. Эзебрии отличаются, особенно в цвете световых отметок, в ширине субапикальной полосы и задних пятном переднего крыла и в развитии темной маргинальной полосы на вершине заднего ход. Согласно Trimen, личинка-легкая охре-коричневая; Каждый сегмент посередине с черной поперечной полосой, одобренной светло -желтым; Голова черная; шипы черные, только боковые шипы на сегментах 5-11 желтый; Живет на видах рода Флерея . Куколка белая со слегка желтоватым тоном и тонкими черными линиями и маленькими черными пятнами; Первые три сегмента брюшной полости с оранжевыми желтыми дорсальными пятнами, в середине которого расположены на небольшом возвышении; точки на голове короткие.
- esebria Hew. The hindmarginal spot of the forewing large and broad, almost reaching the base of cellules 1 a and 1 b and covering the base of cellule 2, brown-yellow; subapical band narrow, its spots in 5 and 6 shorter or at least not longer than the black basal part of these cellules, in the male light ochre-yellow or whitish yellow, in the female white. Hindwing brown-yellow above with a black marginal band about 4 mm. in breadth. Cape to the Congo and British East Africa.
- jacksoni E. Sharpe (57 d) is very similar to the type-form, only differing in having the subapical band of the forewing as dark as the hindmarginal spot and broader; in the female the subapical band is even broader and reaches vein 2, where it touches the hindmarginal spot; the breadth of the marginal band of the hindwing is very variable. Mashonaland to British East Africa.
- ab. ertli Auriv. closely approaches the form jacksoni, only differing materially in having the subapical band of the forewing still broader and white; the hindmarginal spot of the forewing and the ground-colour of the hindwing above are red-yellow in the female, light ochre-yellow in the male Usambara.
- f. pseudoprotea Btlr. closely approximates to the type-form, only differing in having the ground-colour of the hindwing above and the hindmarginal spot of the forewing lighter yellowish and the marginal band of the hindwing narrower. Angola.
- female-ab. amphiprotea Btlr. is also similar to the type-form, the only particular differences being that the dark marginal band on the upperside of the hindwing is not sharply defined proximally and the subapical band of the forewing is light brown-yellow like the other markings. Angola.
- female-f. metaprotea Btlr. The very broad subapical band and the large hindmarginal spot of the forewing touch in cellule 2 and are light brown-yellow; the hindwing is even lighter brown-yellow and has only a dark marginal line instead of the band; approximates to the form jacksoni. Angola.
- female-ab. nubilata Eltr. The darker areas are sepia black. The base of forewing cell, the inner-marginal patch, and the basal half of the hindwing are dark sepia grey. The forewing subapical band is greyish white. Zululand.
The three following forms differ from the preceding in the smaller and narrower hindmarginal spot of the forewing, which always leaves the base of cellules 1 a and 1 b free and also scarcely if at all covers the base of cellule 2.
- masaris Oberth. (57 c) [ this is now species Acraea masaris ] is on an average smaller than esebria; the light markings are red-yellow or brown-yellow in the male and white or light yellow in the female; the subapical band is scarcely broader than in the type-form. Comoro Islands and quite similar forms also in Usambara.
- protea Trim. (57 c) may be at once known by the small, not sharply defined hindmarginal spot of the forewing, which does not extend beyond vein 2; the subapical band of the forewing is narrow and its spots in cellules 4-6 are never longer than the black basal part of the cellules; the base of the hindwing above blackish, often as far as vein 2, and the marginal band of the hindwing broad; the light markings are light yellow in the male, light yellow or white in the female. Cape to Angola and British East Africa
- f. monteironis Btlr. (57 d) is similar to protea and like this has a small hindmarginal spot on the forewing, anteriorly bounded by vein 2; all the light markings are white, rarely light yellow; it differs from protea in the long, broad subapical band of the forewing which is about 6 mm. in breadth and has usually a spot in cellule 2 also. Angola, Mashonaland, German and British East Africa.[3]
Differences between A. esebria and A. jodutta
[edit]- A. esebria
- The dark marginal band on the upperside of the hindwing broad and not sharply defined, long black rays extending far beyond it proximally; the subapical band of the forewing more
than 3.5 mm. in breadth.
- A. jodutta
- The subapical band and the anteriorly broad hindmarginal spot of the fore wing nearly touch at a point on vein 3. A smaller species with a wing expanse of at most 50 mm.
Distribution
[edit]This species is found from the Eastern Cape of South Africa to Zimbabwe and in Mozambique,[2] Malawi, Zambia, southern Democratic Republic of the Congo (Shaba), Angola, Tanzania and eastern Kenya (east of the Rift Valley).
Life cycle
[edit]Eggs
[edit]The eggs are oval in shape.[4]
Larvae
[edit]The larvae feed on Urtica, Laportea peduncularis, Urera trinervis, Urera hypselodendron, Obetia tenax, Pouzolzia procridioides, Pouzolzia parasitica and Fleurya mitis.[5]
Adults
[edit]Adults are on wing year round but are more common in the warmer months,[5] from December to April.[2] These butterflies fly slowly in and around forests and feed from flowers.[2]
Taxonomy
[edit]It is a member of the Acraea jodutta species group - but see also Pierre & Bernaud, 2014 [6]
