This little caterpillar was found in the grass, can't seem to find its correct food source and it hasn't started to make a cacoon yet.
These caterpillars or grubs seal the leaves of soft leaved trees like measa lanceolata and rauvolfia caffra to make a kind of protective purse. The monkeys sometimes spend time unrolling the packages.
