Meganeura is a large ancestor to modern dragonflies, it spawns in the Carboniferous Dimensions Coal Swamps, Rainforests, Highlands and Marshes as a passive mob.
Meganeura flies around the area landing on fallen logs occasionally. It is passive and will flee if attacked. It drops insect plating (50%) and Meganeura Egg (10%).
Meganeura can be bred from Meganeura Eggs, simply place them in an incubator and wait 3 days for it to hatch, it takes a further 2 days for it to mature. Meganeura can sweep small mobs off their feet and send them flying.
