Meganeuropsis permiana

Insecta - Meganisoptera - Meganeuridae

Discussion

Meganeuropsis permiana is the largest insect known, slightly bigger than the closely-related Meganeura, with an estimated length of 33 cm for a single wing (although the fossil itself is only a 14-cm long fragment). Although Meganeuropsis is sometimes called a "giant dragonfly," it is not a true dragonfly - it actually belongs to the extinct order Meganisoptera (formerly known as Protodonata and sometimes called "griffenflies"). Meganeuropsis americana, probably actually the same species, was slightly smaller but is known from a 28 cm-long fragment, the largest complete wing fragment known.
