Description

edit

Sphaerocoris annulus can reach a length of about 15 millimetres (0.59 in).[2][3] The basic color is green, with eleven ring-shaped spots on the scutellum. The colors and the design of these bugs represent a warning to predators. They also emit a noxious odour when disturbed. Main host plants are Gossypium species (Malvaceae), Coffea arabica (Rubiaceae), Citrus species (Rutaceae) and Vernonia amygdalina (Asteraceae).[4] This species reproduces at the beginning of the dry season (November–December). Eggs are laid on the underside of leaves, and nymphs will spend a majority of their time in flowers feeding. Once they molt into adults, however, their feeding becomes more generalized. The full development lasts 56 days.[5][6] Sphaerocoris annulus nymphs are a creamy-white color with black stripes and dots, and gain their colorful spots when they reach maturity. [2]

Distribution

edit

This species is present in tropical and subtropical Africa (Benin, Cameroon, Côte d'Ivoire, Ethiopia, Ghana, Kenya, Malawi, Mozambique, Namibia, Nigeria, Sierra Zambia[3] and Zimbabwe).
