You bug people would probably pick up an injured one and say you were 
rescuing a damsel in distress.

Subject: [NatureNS] Odonates at Belchers Marsh


Hello,

Last Friday afternoon, I took a quick walk around Belchers Marsh, a local
wetland located on Parkland Drive in Clayton Park West.  I was focussed on
new flowering plants and odonates.
There were a lot of damsels and dragonflies about, including one species
which I had never seen previously (and thought that I'd never see!).  These
included:

 - White Corporal (Libellula exusta)
 - Four-spotted Skimmer (L. quadrimaculata)
 - Hudsonian Whiteface (Leucorrhinia hudsonica)
 - Elfin Skimmer (Nannothemis bella)!!!

The latter species has to be seen to be believed!!  I didn't carry my field
guide with me but its diminutive size is distinctive.  I only really noticed
the female of the species due to its bee-like appearance but I'm pretty sure
that there were some males around.  In the field, I guesstimated the size to
be ~2 cm which is fairly close to that given in the field guide.  According
to my Mass. field guide, the Elfin Skimmer is the smallest dragonfly in
North America!  All of the damsels seen on Friday were larger than this
species!!  Fascinating.....

Cheers,
