Yet one species, Mecistogaster martinezi, has been observed apparently "tossing" eggs from its abdomen onto the surface of the water while in flight. This behavior may allow the insect to avoid predators such as spiders from which it would otherwise be unable to escape in the small, confined space of a phytotelma. [ 15 ]
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.
The genus belongs to the Meganeuridae, a family including other similarly giant dragonfly-like insects ranging from the Late Carboniferous to Middle Permian. With single wing length reaching 32 centimetres (13 in) [ 1 ] and a wingspan about 65–75 cm (2.13–2.46 ft), [ 2 ] [ 3 ] [ 4 ] M. monyi is one of the largest-known flying insect species .
Compared to dragonfly larvae, the nymphs show little variation in form. They tend to be slender and elongate, many having morphological adaptations for holding their position in fast flowing water. They are more sensitive than dragonfly nymphs to oxygen levels and suspended fine particulate matter, and do not bury themselves in the mud. [25]
The prothorax is notably elongated and mobile, giving the group its common name of snakefly. The three pairs of legs are similar in size and appearance. The two pair of dragonfly-like wings are similar in size, with a primitive venation pattern, a thickened leading edge, and a coloured wingspot, the pterostigma. Inocelliids lack a cross vein in ...
Grabbing a glimpse, let alone a photo, of a dragonfly can be pretty tricky, since they're among the fastest insects in the world. But even observing the swarms from afar can be worth your while ...
Across Far Eastern civilizations like Japan, there is a particularly positive dragonfly meaning—and that's true for many Indigenous American cultures, too. In the former, dragonflies represent ...
Meganisoptera is an extinct order of large dragonfly-like insects, informally known as griffenflies or (incorrectly) as giant dragonflies. The order was formerly named Protodonata, the "proto-Odonata", for their similar appearance and supposed relation to modern Odonata (damselflies and dragonflies).
