At the end of the mask is a set of fanglike pincers used to seize prey such as worms, crustaceans, tadpoles, and small fish. [104] The Southern United States terms "snake doctor" and "snake feeder" refer to a folk belief that dragonflies catch insects for snakes or follow snakes around and stitch them back together if they are injured. [18] Their altitudinal limit is about 3700 m, represented by a species of Aeshna in the Pamirs. [12][23], An adult dragonfly has three distinct segments, the head, thorax, and abdomen, as in all insects. Most Anisoptera species are tropical, with far fewer species in temperate regions. Types of Dragonflies for Dragonfly Identification - Green Nature Disproportionately large, the mask folds beneath both the head and thorax when it is not in use. Three terminal appendages are on segment 10; a pair of superiors (claspers) and an inferior. Freshly emerged adults, known as tenerals, are often pale, and obtain their typical colours after a few days. Because of their connection to water, dragonflies are tied to our emotional selves. They are not native to Iceland, but individuals are occasionally swept in by strong winds, including a Hemianax ephippiger native to North Africa, and an unidentified darter species. dragonfly, (suborder Anisoptera), also called darner, devils arrow, or devils darning needle, any of a group of roughly 3,000 species of aerial predatory insects most commonly found near freshwater habitats throughout most of the world. This style creates more thrust, but less lift than counter-stroking, Synchronised-stroking, with forewings and hindwings beating together, is used when changing direction rapidly, as it maximises thrust. But the praying mantis anatomy is designed to be a predator. Perching dragonflies, on the other hand, who rely on solar energy for warmth, skillfully position their bodies to maximize the surface area exposed to sunlight. Birds and other predators consume a significant number of young dragonflies in the first few days after their emergence. Dragonflies, like damselflies, exhibit a mating posture unique to the Odonata. Water can be forcibly expelled in this way, resulting in jet propulsion as a means of escape. Omissions?

The mouthparts are adapted for biting with a toothed jaw; the flap-like labrum, at the front of the mouth, can be shot rapidly forward to catch prey. [45] There is also conflict between the males and females. [64] In general, large dragonflies like the hawkers have a maximum speed of 3654km/h (2234mph) with average cruising speed of about 16km/h (9.9mph).

The most obvious fact relating to the glasswing butterfly is that it contains transparent wings, usually with an outline of black or orange -- although the colors can vary. [16], Some dragonflies, including libellulids and aeshnids, live in desert pools, for example in the Mojave Desert, where they are active in shade temperatures between 18 and 45C (64 and 113F); these insects were able to survive body temperatures above the thermal death point of insects of the same species in cooler places. Likewise, the dragonfly nymph pulls water into its anus to facilitate gas exchange.
