According to the faqs on this site they don't bite or sting:-

I also read that they lay the eggs singly but fly past multiple times to
lay the eggs in the same area. They also spend a long time in the larvae
stage (around 6 months) so conceivably your two could have been from the
same batch and there might be more.

Seems to be some reasonable info in this faq

Gill: No they don't bite or sting as adults, but the larvae (nymphs) do
have mighty pinchers and according to that same site:
http://www.dragonflysoc.org.uk/faq.htm#feeding

"The larvae, which live in water, eat almost anything living that is smaller
than themselves. The larger dragonfly larvae are known to catch and eat
small fish or fry. Usually they eat bloodworms or other aquatic insect
larvae."

Elaine: Have you introduced any new plants or driftwood to the tank
recently? if so, that may be your source if the eggs were on whatever it
was.


Nope. I haven't introduced anything for months. I always soak new
plants in potassium permanganate anyway.

I'm thinking they must have come in with live food. I feed frozen
bloodworms, glassworms, baby brine shrimp, daphnia and cyclops, daphnia
from a jar, and occasionally live brine shrimp. I was feeding live
blackworms a while ago, so that could be a source, but I stopped at
least two months ago when I got some picky fish weaned to frozen food.
I was rinsing the blackworms for at least three days before I used them,
and there are no larvae (touch wood) in the other tanks that got many
more blackworms than the guppy tank. If the eggs survive freezing, it
may be the cyclops, because I've only really fed those to the guppies.

Sheesh. I wish I knew for sure...
