How male dragonflies adapt wing color to temperature

New research from Case Western Reserve University in how dragonflies may adapt their wing color to temperature differences might explain color variation in other animals, from lions to birds.

Are the Paleozoic era's giant dragonflies still among us?

Don't worry. This isn't an announcement of a new invasion from elsewhere, but a leap into the past in the Paleozoic: the time of giant insects, 100 million years before the dinosaurs, during which insects also had their T-Rex: ...

Dragonfly enzymes point to larger evolutionary dynamics

Although evolution has left dragonflies virtually unchanged for roughly 300 million years, new research by a UTM biologist reveals that understanding small physiological activities in these insects could reveal a deeper understanding ...

How deadly dragonfly wings bust up bacteria

Scientists have revealed the intricate detail of how dragonfly wings kill bacteria, thanks to new methods for using very powerful microscopes to see nature's smallest structures in three dimensions.

Researchers discover what is on the menu for dragonflies

Researchers from the Universities of Turku and Helsinki, Finland, have discovered the prey species of adult dragonflies and damselflies, as modern laboratory techniques enabled the study of the insects' diet. In the study, ...

Russia-tied hackers can gain control of power network: report

A Russia-linked cyber-espionage group has hacked into the controls of electricity distribution networks in the US and Europe, raising the risk of malicious, remotely-caused blackouts, computer security firm Symantec said ...

Dragonfly brains predict the path of their prey

New research from Australia and Sweden has shown how a dragonfly's brain anticipates the movement of its prey, enabling it to hunt successfully. This knowledge could lead to innovations in fields such as robot vision.

Dragonfly

A dragonfly is a winged insect belonging to the order Odonata, the suborder Epiprocta or, in the strict sense, the infraorder Anisoptera (from Greek ανισος anisos, "uneven" + πτερος pteros, "wings", due the hindwing being broader than the forewing). It is characterized by large multifaceted eyes, two pairs of strong transparent wings, and an elongated body. Dragonflies are similar to damselflies, but the adults can be differentiated by the fact that the wings of most dragonflies are held away from, and perpendicular to, the body when at rest. Dragonflies possess six legs (like any other insect), but most of them cannot walk well. Dragonflies are some of the fastest insects in the world.

Dragonflies are valuable predators that eat mosquitoes, and other small insects like flies, bees, ants, wasps, and very rarely butterflies. They are usually found around marshes, lakes, ponds, streams, and wetlands because their larvae, known as "nymphs", are aquatic.
