By enabling the twisting and folding of the wings this small muscle has probably enabled insects to evolve the complex wing-cases seen in several groups, as well as other adaptations. It seems clear that the presence of this flexor muscle, along with other related features, means that the Neoptera are a monophyletic group.
Paleoptera | insect infraclass | Britannica
In the Paleoptera the wings are held aloft above the back, as in mayflies, or held extended permanently on each side of the body, as in dragonflies. Throughout the Neoptera there is a wing-flexing mechanism (secondarily lost in butterflies) that enables the wings to be folded back…

All orders that share this “primitive” condition are grouped as Paleoptera, a subdivision (infraclass) within the subclass Pterygota. The word paleoptera is derived from the Greek words “paleo-” meaning primitive, and “ptera” meaning wings.

Paleoptera: Odonata – UNBC BIOL 322, Entomology
35 Paleoptera: Odonata Odonata. The Odonata (“odon” = “tooth”) includes about 5000-6000 species, with 87 species in 10 families known to occur in BC. The order is, in most literature, divided into two suborders, the Anisoptera (dragonflies; “aniso” = “unequal”) and the Zygoptera (damselflies; “zygo” = “joined together”).
