Thomisus stenningi

Females of T. stenningi are notably able to change their coloration from white to yellow, and occasionally freshly caught specimens may display a pink tint. This color-changing ability is characteristic of many crab spiders and aids in camouflage when hunting on flowers. The species is morphologically similar to Thomisus onustus, sharing similar body shape and color-changing abilities. However, the two species can be distinguished by differences in the structure of both male and female genitalia. The embolus shape of the male pedipalp in T. stenningi is similar to that of T. boesenbergi and T. dalmasi, but differs in the presence of an apophysis on the patella. Adults are active throughout the year, including winter months, with peak abundance occurring from October to March.

Thomisus stenningi has been recorded throughout Africa, including South Africa (all provinces), Botswana, Kenya, Tanzania, Uganda, Zambia, Zimbabwe, Angola, Guinea, and Zaire. The species also occurs in the Seychelles and Yemen. In South Africa, the species has been extensively documented across all nine provinces, ranging from 6 to 3,337 meters above sea level.
