Megasecoptera
Encyclopedia
Megasecoptera is a paleozoic
insect
order. There are 22 known families of megasecopterans, with about 35 known genera.
, the megasecopterans had sucking mouthparts. The suctorial mouth parts were probably used to pierce plant casings and extract high-quality plant materials, such as spores and pollen.
Unlike some earlier insects, megasecopterans bore two pairs of wings, which are nearly of the same size. The wings probably were held horizontally, as in dragonflies
(Odonata, Anisoptera). The wing bases tend to be very slender and petiolated, as in damselflies (Odonata, Zygoptera). The body was usually long and thin, although the genus Protohymen was rather stouter and shorter than a typical megasecopteran. Another distinctive feature was the presence of a number of fine processes projecting from the body, which in some cases could be longer than the body itself, forming long fringes on the insect's underside.
During their relatively brief period of existence, the Megasecoptera were rather successful. It has been estimated that this insect order accounted for 50% of the insect biomass in some locations, but the available evidence might be misleading..

Overview
Like all other paleodictyopteroidsPalaeodictyopteroidea
The Palaeodictyopteroidea or Paleodictyopterida are an extinct superorder of Palaeozoic beaked insects, characterised by unique mouthparts consisting of 5 stylets. They represent the first important terrestrial herbivores, and the first major group of herbivorous insects...

Dragonfly
A dragonfly is a winged insect belonging to the order Odonata, the suborder Epiprocta or, in the strict sense, the infraorder Anisoptera . It is characterized by large multifaceted eyes, two pairs of strong transparent wings, and an elongated body...
