With a wingspan of over 30 centimeters long, Meganeura was the largest flying insect of its time (Sánchez-Herrera & Ware 2012). It probably appeared very similar to extant (still alive) dragonflies, though more than 4.5 times the size of the average dragonfly. Its body had a long slender abdomen and large round eyes. An accurate description of Meganeura's body is hard to come by; the fossil specimens are typically incomplete (Carpenter 1943). It is likely that Meganeura was colorful like modern dragonflies. Its wing morphology suggests that Meganeura was just as fast as modern dragonflies, though its gigantean size implies that it was less agile (Sánchez-Herrera & Ware 2012). Like modern dragonflies, it had two sets of wings: hind wings and fore wings. Its wings were laced with veins, which bring nerves and vital nutrients to the wing. The area around the veins usually strengthens, adding structure and rigor to the wing and increasing flight ability.
