Hymenoptera is a large order of insects. The word Hymenoptera means membrane winged. Wasps, bees, and ants belong to this order. So do the gallflies, which make the gall formation on oak trees and rosebushes. The Hymenoptera differ widely from each other, but all except the worker ants and a few others have four transparent, membranous wings. Many of these insects are valuable to man. Some destroy other insects. Others help pollinate plants, and produce honey and beeswax.
