What a brilliant design! It’s light in weight and aerodynamic. It’s been an inspiration to man,
to build flying machines – remember a helicopter (Biomimetics).
Let me share a few facts:
Dragonflies are expert fliers. They can fly straight up & down, and hover like a helicopter.
They only eat their prey they catch-while flying. That says about its efficient hunting skills.
Most of the dragonfly’s head is its eye, which has thousands of lenses so they have incredible vision
that encompasses almost every angle, except directly behind them.
Dragonflies are useful in controlling mosquito population. Mosquitoes are one of their primary food sources!
It’s also heard that a single dragonfly can eat 30 to hundreds of mosquitoes per day(!).
Dragonflies spend most of their lives in the larva stage (up to three years, depending on the species).
The adult, winged-stage only lasts a few weeks. Mating is the primary reason for their winged-stage.
So when you see a winged dragonfly, you know it’s toward the end of its lifespan. Sad, but true.
