Rhyothemis variegata, [2] known as the common picture wing [3] [4] or variegated flutterer, is a species of dragonfly of the family Libellulidae, found in South Asia, [1] [5] Indochina and southern China.
The wings have a network of veins; between the veins the wings are generally transparent, but may be partly colored. [1] In most Odonata there is a structure on the leading edge near the tip of the wing called the pterostigma. This is a thickened, hemolymph–filled and often colorful area bounded by veins.
The leading edge of each wing has a node where other veins join the marginal vein, and the wing is able to flex at this point. In most large species of dragonflies, the wings of females are shorter and broader than those of males. [31] The legs are rarely used for walking, but are used to catch and hold prey, for perching, and for climbing on ...
It is very small, reaching a total length of no more than 25 millimetres (0.98 in). The males have orange or amber wings. Both sexes have a red pterostigma. [5] The eastern amberwing dragonfly is one of the only types of dragonfly that actively mimics a wasp. The yellow and brown stripes on its abdomen encourage predators to stay away.
Odonata is an order of predatory flying insects that includes the dragonflies and damselflies (as well as the Epiophlebia damsel-dragonflies). The two major groups are distinguished with dragonflies (Anisoptera) usually being bulkier with large compound eyes together and wings spread up or out at rest, while damselflies (suborder Zygoptera) are usually more slender with eyes placed apart and ...
Trithemis annulata is a robust medium-sized species with a wingspan of 60 mm (2.4 in). The mature male has a dark red head and a yellow labium with a brown central spot. The eyes are red with white spots on the rear edge, and the frons is dark metallic purplish-red.
The common whitetail or long-tailed skimmer (Plathemis lydia) is a common dragonfly across much of North America, with a striking and unusual appearance.The male's chunky white body (about 5 cm or 2 inches long), combined with the brownish-black bands on its otherwise translucent wings, give it a checkered look.
According to Leonard Tan of the blog Singapore Odonata, males lack the transverse brown patches near the wing tips that females have. Apart from differences in wing patterns, males and females of the giant hawker are very similar in appearance. [12] The giant hawker is sexually dimorphic. Males are smaller than females.
