Behaviour:
Both pairs of wings are raised upwards until they are perpendicular to the body, and one of the hind feet is drummed on the substrate (e.g. the surface of a leaf). The other hind leg is extended backwards to act as a support. The drumming is extremely rapid and is in very short burts of less thn a second. There are usully a number of these burts, the first ones being of shorter duration than the remainder. The whole process lasts no more than a few seconds. During the drummin the abdomen also vibrates, but is held clear of the surface on which the insect is resting. [1]
