Glossy Wild-currant, Shiny-leaved Rhus, Blinktaaibos
Searsia lucida (formerly Rhus lucuda) ANACARDACEAE (the mango family)
A fascinating insect-plant relationship plays itself out with the Glossy Wild-currant Rhus lucida and the Jumping Gall Moth Scyrotis athleta. In the sand and leaf-litter beneath Searsia lucida one can sometimes see small (about 6 mm) oval balls that jump. In the ball is the larva of a moth, Scyrotis athleta (family Cecidosidae). The movement and jumping is a response to heat and facilitates repositioning of the ball into ideal pupating conditions in the soil and leaf-litter. It is quite a mystery how such a small larva in such a confined space is able to exert the force required to jump (up to 10 cm). Janse (1920) concluded that it is done by careful positioning inside the ball and rapid contracting and relaxing of muscles.
