Picasso Shield Bug aka Zulu Hud Bug (Sphaerocoris annulus)
These beautifully patterened true bugs (order Hemiptera, family Scutelleridae) are found throughout much of sub-saharan and northeastern Africa. They feed on the nectar and internal juices of a wide variety of plants with their sucking and piercing proboscis (straw like mouth part). Eggs are deposited on the under sides of leaves. The young nymphs spend most of their time in flowers feeding, and they take a little under 2 months to molt and grow into adults (when they will live become more generalized feeders).
