Adults are exceptionally large for damselflies, with wingspans as high as 19 cm (7.5 in.) reported for Megaloprepus [6] and body length up to 13 cm (5.1 in.) for Pseudostigma aberrans. [7] The pterostigma —a thickened, pigmented cell found on the leading edge of the wing in other odonates —is either missing or else modified into a ...
Meganeura is a genus of extinct insects from the Late Carboniferous (approximately 300 million years ago). It is a member of the extinct order Meganisoptera, which are closely related to and resemble dragonflies and damselflies (with dragonflies, damselflies and meganisopterans being part of the broader group Odonatoptera).
The Phasmatodea (also known as Phasmida or Phasmatoptera) are an order of insects whose members are variously known as stick insects, stick bugs, walkingsticks, stick animals, or bug sticks. They are also occasionally referred to as Devil's darning needles , although this name is shared by both dragonflies and crane flies. [ 1 ]

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).
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 ...
In November, Jimmy Cragg came down with what his mother Wendy described as common flu-like symptoms: “He had a cold and a cough, and a dry mouth and sore throat,” Wendy, 43, told South West ...
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 ...
