Adults: They're small (0.5- 3.0mm) and described as 'mosquito-like'. They possess one pair of wings; the other pair are modified and look like tiny, club-shaped appendages, poking out between the insects' thorax and abdomen. These are specialised body organs used to improve balance while in flight. The wings are also hairy, which is unusual for True Flies (order: Diptera). The antennae are long with tiny delicate hairs. The antennae are what's known as Moniliform; meaning they appear like a string of beads. The head is small and cone-shaped, and the legs long like stilts.
Larvae: The larvae look like small yellow, red or orange; sometimes they can be creamy-green as they grow larger. They lack heads and legs. They are often associated with abnormal bumps and lumps on the plant, which is a result of their feeding behaviour.
