scorpions, dragonflies, barnacles, copepods and centipedes. Remipedes, one of the two species of Xenocarida in the study, had to be fetched from partially submerged limestone caves in the Yucatan peninsula and preserved just so.

Cicadas, locusts, crickets, dragonflies, flies are spared not either. While two billion people are perfectly fine with eating insects,

what an animal looks like (dragonfly). This last category however is where the naming scheme can become misleading.

Is a dragonfly a true fly? No it belongs to the Order odonata along with damselflies whereas true flies (house flies fruit flies etc.)

belong to the Order diptera. And is a dragonfly a dragon? That's probably a more obvious no.

Here is a list of seven other imaginative but potentially misleading animal names: A seahorse might slightly resemble a horse without the fur

and with a different kind of tail but it is really a fish that belongs to the Syngnathidae family along with pipefishes and leafy sea dragons.

and dragonflies ruled the skies. Tetrapods were becoming more specialized and two new groups of animals evolved.

and off the California coast and identified danger zones where extensive fishing may harm the turtles according to Discovery. com. Dragonflies In a laboratory in Ashburn Virginia researchers are studying dragonflies by strapping tiny backpacks to the insects.

The backpacks though don't have straps they're actually glued onto the dragonfly's shoulders

Pesticide use has reduced sharply the regional biodiversity of stream invertebrates, such as mayflies and dragonflies, in Europe and Australia, finds a study published today in the Proceedings of the National Academy of Sciences1.

I had to stich myself up with a sewing needle and fishing line. Those things nearly killed

and scare away damselflies which feed on small spiders but avoid larger ones. These insects in the family Pseudostigmatidae are the largest damselflies in the world.

To the untrained eye they resemble dragonflies. Our working hypothesis which we plan on testing is that the Cyclosa makes a decoy spider that is larger than the size of spiders Pseudostigmatids will take thereby gaining some protection from being eaten by these spider specialists says Ola Fincke a collaborating researcher at the University of Oklahoma

and the world expert on helicopter damselflies as Reeves puts it. Over the course of my trip and Reeves's month in the jungle he goes about laying the groundwork to test this hypothesis

and makes several interesting discoveries. First Reeves devised a method to collect the webs (which he doesn't want to share in detail for proprietary concerns) that he will use in the future to collect the animals and their silken firmaments and expose them to damselflies.

The idea is to see if the winged creatures pluck more spiders from webs where the decoys have been removed--that would provide evidence that the decoys are meant indeed to scare off the insects.

When he returns to the jungle before long he will explore the eating habits of damselflies to see

Techject a company that spun off from work done at the Georgia Institute of technology recently unveiled a robotic dragonfly with a six-inch wingspan.

The Techject Dragonfly takes advantage of an aerodynamics principle called resonance. When wings flap at their most efficient frequency hich happens

Unlike the much larger Instanteye Nano Hummingbird and Dragonfly drones Robobees must be connected to an external power source.

and dragonflies and are important members of the food chain right up to fish and birds. Biological diversity in such aquatic environments can only be sustained by them

They are called crane flies also mosquito hawks. Crane flies are harmless. They don't bite and they don't eat mosquitoes as some people claim he tells them.

One day he spied a new species of dragonfly on his way to breakfast. It had emerged from its larval form in the small pool of water caught in the cupped leaves of a bromeliad plant.

Dragonflies don't live on bromeliads. Or do they? Those are the kinds of things that you know you don't plan for them you can't plan for them de la Rosa said.

There was only one known species of dragonfly in the world that lives in bromeliads. Now there will be two.
