Information report on dragonflies

Name: Jazire
Information report on dragonflies

Dragonflies are flying creatures with 4 large transparent wings that are slightly narrow at the start of each.

These mystical creatures have only three body parts. The head, the thorax, and the abdomen. The dragonfly has two large eyes that take up most of its head. There are also three pairs of jointed legs attached to its short, thin thorax.

Dragonflies and damselflies start life in the water, so they are commonly spotted around ponds, streams and other water compounds. Considering dragonflies are great flyers, they are sometimes found a long way from water.

Dragonflies are fast moving critters, and have the average speed of 4.5 metres per second (10 mph). They move by alternating their wings one at a time, which allows the dragonfly to hover like a helicopter.

Adult dragonflies mostly eat other flying insects like midges, mosquitoes, moths and butterflies. The larvae, or nymphs, that live in the water will basically eat anything smaller than themselves.

Dragonflies have a fierce behaviour and are very brave hunters, in fact if modern day dragonflies were the same as dragonflies were back then, then swimming in water compounds would be much much scarier because there would be a slight chance of you getting attacked.

There are three stages in the life cycle of all dragonflies. The egg, the larva(nymph), and the adult. Surprisingly, dragonflies only live as adults for about 7 months! Less if they’re unlucky. The dragonfly can live up to more than a year in total. Dragonflies and damselflies mate whilst in the air, and when a damselfly lays an egg, she will find a suitable plant to put it on, but if she can’t find one, she drops it in the water.
