FAQ (Frequently Asked Questions)
How long do they live?
As flying adults, dragonflies live only a few weeks, but if you include
their underwater stage as nymph, their lives span from 1 summer up to 3
years.
What do they eat?
Adult flying dragonflies eat other smaller flying insects, esp.
mosquitoes and gnats. Nymphs eat other underwater life forms such as mosquito
larva. Larger nymphs can and will eat pollywogs and small fish.
Where do they go in the winter?
Adult dragonflies die of old age as winter approaches, but nymphs from
spring, summer and fall laid eggs are still maturing underwater.
How many kinds are there?
On Earth there are over 5,400 species of dragonflies and damselflies.
In the USA and Canada there are 435 species altogether. New species are still
being discovered, even here in the USA
Do they bite or sting?
Dragonflies do not have stingers and cannot sting! Since they have a
mouth, they can bite, but they bite prey, not humans, unless handled roughly.
Their bite would be like a hard pinch.
Can they darn your lips closed?
Of course not! An old folk tale said that if you told lies a dragonfly
would darn your lips closed. However, there are other bad consequences that
befall those who tell lies!
Were they really here when dinosaurs were on Earth?
Yes! Dragonflies have existed for over 200 million years! In fact, they
were here before the dinosaurs,and are among the most ancient creatures still
populating our planet Earth.
