The Damselfly is one of our favourite insect.  As a larva it feeds on mosquito larvae and as an adult it feeds on adult mosquitos.  I guess you can tell that mosquitos are not on our favourite insect list.  In flight the damselfly looks like the bigger dragonfly but sitting still, a dragonfly still has its two pairs of wings stretched out on either side unlike the damselfly which folds them up behind the thorax.
