Megaloptera (alderflies, dobsonflies, fishflies)

Like Neuroptera, Megaloptera have chewing mouthparts, long antennae, and two pairs of membranous wings. Both orders have moderate cross-veins forming many rectangular cells, but Megaloptera lack forked veins along the wing margins. Metamorphosis is complete. Dobsonflies are the largest and most common members of this order. (Florida 4-H Bug Club: Megaloptera: Dobsonflies, Alderflies and Fishflies).
