(i) Pair Formation The most striking behaviour of this species is the loud and frequent crepitation flights. The crepitation rate (wing-stroke rate) is rapid and results in a continuous buzzing sound varying in duration from 0.5 to 5.0 sec. Flights are rapid and no more than 2 ft above the ground. The hindwings are somewhat contrastingly marked, but flights were visually inconspicuous to me. A second signal which probably also serves a pair-forming function was produced bymalesbetweenflights. Shortlyafteralightingfromacrepitationflightfivedifferent males produced ticking movements delivered at approximately 8 per 10 sec. As in other species this consisted of repetitive kicking out with the hind tibiae and striking the wing. Only one hind leg was used to deliver each series. One male used the left leg after one flight and the right leg after a second flight. Except for signalling, males remained motionless between flights. (ii) Agonistic Behaviour No agonistic behaviour was observed.
