Facts about dragonflies

                                           Facts about dragonflies


1.Why does  dragonflies have a small body but big eyes.these ferocious aerobatic hunters are renowned for their enormous compound eyes, which give them the optical acuity necessary to seize prey in mid-air over open water. Both dragonflies  and damsels have short antennae, so vision is their primary means of nav capturing and  food gating .





2.How long does a dragonfly live for . At the shortest the life cycle of a dragonfly from egg to the death of the adult is about six months. There are even dragonflies that live for several years as aquatic larvae before they emerge and live for a few months as adults. Most dragonflies don't die of old age but are caught by
Predators.

3. How can you tell a male from a female. Dragonfly Gender - Male Or Female?
I can't tell you how many times I have been asked, what my secret is for identifying the gender of a dragonfly?

Not always worded that way, but that is the general gist of the question asked.
I spent much of the morning looking through hundreds of images so that I could answer that question in terms that I felt most people could understand.
It was not as easy as I had first expected it to be, but I feel it is an effective tool to help answer the question of dragonfly gender.
The pictorial guide I created is not geared toward a dragonfly expert, but rather the beginning dragonfly enthusiast.
My hope is that it will help you to understand and better identify dragonfly genders.


4.What do dragonflies eat ? Adult dragonflies mostly eat other flying insects, particularly midges and mosquitoes. They also will take butterflies, moths and smaller dragonflies. The larvae, which live in water, eat almost any living thing smaller than themselves. Larger dragonfly larvae sometimes eat small fish or fry



5.Where do dragonflies live?Dragonflies start their life in water, therefore they are often found near water: ponds, lakes,  puddles. Since dragonflies are very
good flyers they can sometimes be found a very long way from water.ls, streams, rivers and swamps. Some dragonflies with a short larval cycle (a few weeks) also can live in rain .
