The behavior of unpaired males of the dark-winged A.f. atra Gloyd and A.f. fumipennis (Burnt.) was compared with that of the clear-winged A.f. violacea (Hag.). The dark and clear-winged subspecies differed primarily in that the former had more wing-clapping episodes per unit of time, more claps per episode, and a greater clap angle. — The reproductive behavior of the dark-winged A.f. alra was similar in most respects to that of the clear-winged species of Argia. Without courtship, males seized females at water and intramale sperm translocation in tandem (X = 14.6 sec) and the wheel position (X = 24.4 min) quickly followed. The wheel consisted of two phases: an initial long period (X = 19.9 min) of pumping when sperm from a previous mating was probably removed, followed by a brief (X = 4.5 min) terminal period without pumping when the male probably inseminated the female. After an exploratory period averaging 33.8 min, pairs oviposited in tandem at the water surface for an average of 58.2 min. U nlike clear-winged species of Argia. A.f. alra males frequently wing clapped during the wheel position, and both sexes clapped during oviposition.
