Aren't these insects incredible? They are rainbow shield bugs (Calidea dregii, Hemiptera) from Africa, and they live on developing seeds of Jatropha, an Euphorbiaceae (like poinsettia) that is being developed as a biofuel. Apparently the males do a courting dance before they mate and they are the most active during the hottest day, so no siesta for these.
