"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."
