"The damselfly's
mating pattern is unusual. The male deposits sperm by bending the
abdomen forward and then clasping the female behind the head with
its claspers on the tip of his abdomen. The female then loops her
abdomen forward and picks up the sperm from the male. The mating
pairs are seen flying and clinging in tandem. Most species have one
generation per year depending on the species, although they complete
their life cycle from 1-2 years."
