From: Pigmentation in Drosophila melanogaster reaches its maximum in Ethiopia and correlates most strongly with ultra-violet radiation in sub-Saharan Africa

Figure 2

Natural variation of thoracic and abdominal pigmentation between three sub-Saharan populations of Drosophila melanogaster : (A-B) typically pigmented flies from Siavonga, Zambia, (C-D) moderately melanic flies from Nkouondja, Cameroon, and (E-F) intensely melanic flies from Dodola, Ethiopia. Pigmentation traits measured in this study on (A) lateral and (B) dorsal views: 1 = A4 black stripe width, 2 = A4 total tergite width, 3 = A4 background, 4 = mesopleural (MPL), 5 = presutural, 6 = humeral.
