Edit 2 - Vector version, by Gustavb – same text as Edit 1 ((Note: This is a new file, not nominated file from 2006)) File:Dragonfly morphology edit 4.svg Edit 4 - more wing adjustments I am self nominating a peice of my own work which shows the basic morphology and anatomy of a female dragonfly (specifically a Green Darner).
Dragonfly anatomy. The imago (adult stage) has a large head, well-developed, compound eyes, legs that facilitate catching prey (largely other insects) in flight, two pairs of long, transparent wings that move independently, and an elongated abdomen.
The tau emerald is a medium-sized, black and yellow dragonfly with long legs, [4] reaching a body length of about 50 mm. [5] As is unique to dragonfly and mayfly species, H. tau has flight muscles attached directly to the wings, [6] and in both the males and females the inboard edge of the hindwing is rounded. [4]
Diagram of a typical insect leg. The typical and usual segments of the insect leg are divided into the coxa, one trochanter, the femur, the tibia, the tarsus, and the pretarsus. The coxa in its more symmetrical form, has the shape of a short cylinder or truncate cone, though commonly it is ovate and may be almost spherical.
Common worldwide or nearly worldwide genera are Aeshna and Anax. Anax includes some of the largest dragonflies, including the North American A. walsinghami, Hawaiian A. strenuus, European A. imperator and A. immaculifrons, and African A. tristis, but these are all exceeded by another member of the family, the Asian Tetracanthagyna plagiata, which by wingspan and weight is the world's largest ...
The result was interpreted as a triple-jointed leg arrangement with some additional appendages but lacking the tarsus, where the wing's costal surface would normally be. This mutation was reinterpreted as strong evidence for a dorsal exite and endite fusion, rather than a leg, with the appendages fitting in much better with this hypothesis.
Dromogomphus spinosus, the black-shouldered spinyleg, is a species of dragonflies in the family Gomphidae.. Like other spinylegs, D. spinosus have long spines on their legs that help in the capture of prey. [2]
The emperor dragonfly is a large and bulky species. It is 73–82 mm (2.9–3.2 in) long, with average being 78 mm (3.1 in) and males growing larger than females. [2] [6] The average wingspan is 104 mm (4.1 in). [6] When they first emerge, both sexes appear pale green with brown markings. The legs are brown with a yellow like base.
