蜻蜓目 ODONATA
Odonata means “toothed jaws,” and indeed the larger species of dragonflies and damseflies may give you a startling but harmless bite.Despite what your mother told you about dragonflies sewing up your lips, they cannot stitch or sting you in any way.
The order Odonata is subdivided into three suborders: Anisoptera, the dragonflies; Zygoptera, the damselflies; and Anisozygoptera, mostly fossilized species with only two known living members.
- physical features
extremely large eyes (in proportion to its head)
a long, slender abdomen
Large mandibles(jaw), chewing prey quickly and easily, an important feature since these insects tend to eat on the move.
Thorax tilted, positioning the legs just below the mandibles where they function as a prey-catching basket.
“Primitive winged,” ( wings that cannot be folded). giving Odonates the interesting abilities to hover, fly backward, and take off vertically, similar to a helicopter.
Being able to rotate their heads nearly 360 degrees, giving them an almost limitless field of view.
Dragonflies and damselflies have tiny antennae, so vision is their primary means of navigating and capturing prey.
——————————————————————————-
Odonate eggs are laid in water, where they hatch into wingless naiads. The naiads have gills, and will molt up to 15 times, depending on the species. Some naiads remain in their aquatic environment for as long as two years before reaching adulthood. The final molt produces functioning wings, and the adult dragonfly or damselfly can hunt over water or land.
- Habitat and Distribution:
Odonates inhabit every continent except Antarctica, in habitats where fresh water is present. Most species in the order are tropical.
- Major Families and Superfamilies in the Order:
- Aeshnidae – darners
- Gomphidae – clubtails
- Libellulidae – common skimmers and chasers
- Coenagrionidae – narrow-winged damselflies
- Corduliidae – emeralds
