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).
A large dragonfly seen in flight with a bent abdomen is most likely to be A. imperator rather than A. parthenope. A. parthenope has a blue saddle at S2 and S3 which can be seen in flight, which is in contrast to the rest of the abdomen, which is brown. A yellow ring is at the base of S2. The eyes are green.
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]

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 adult insects are less well known due to their relatively short lifespans in comparison with the larvae. Adults, sometimes known as antlion lacewings, mostly fly at dusk or just after dark and may be mistakenly identified as dragonflies or damselflies. Antlions have a worldwide distribution.
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").
