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).
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 ).
Damselflies are flying insects of the suborder Zygoptera in the order Odonata. They are similar to dragonflies (which constitute the other odonatan suborder, Epiprocta) but are usually smaller and have slimmer bodies. Most species fold the wings along the body when at rest, unlike dragonflies which hold the wings flat and away from the body.
Dragonflies and their relatives are similar in structure to an ancient group, the Meganisoptera or griffinflies, from the 325 Mya Upper Carboniferous of Europe, a group that included one of the largest insects that ever lived, Meganeuropsis permiana from the Early Permian, with a wingspan around 750 mm (30 in).

Epiophlebia is a genus of damsel-dragonfly native to the Indian subcontinent, East Asia, and Southeast Asia. It is the only living genus of Odonata to neither be a dragonfly nor a damselfly. [1] It is the sole member of the family Epiophlebiidae, which is itself the sole living representative of the infraorder Epiophlebioptera.
The common name refers to the wide, iridescent wings along with the unique fluttering flight the species exhibits which resembles that of a butterfly. [ 3 ] [ 9 ] [ 11 ] It shares this Japanese common name with the related Rhyothemis variegata , which is known as オキナワチョウトンボ ( okinawa chou-tonbo , "Okinawa butterfly dragonfly").
Epiophlebia laidlawi, the Himalayan relict dragonfly, is one of four species of Epiprocta in the family Epiophlebiidae.They have at one time been classified as a suborder Anisozygoptera, considered as intermediate between the dragonflies and the damselflies, partly because the hind wings and fore wings are very similar in size and shape, and partly because the insect at rest holds them back ...
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 ...
