Amber is actually fossilized tree resin, not tree sap as is commonly thought. Amber fossilization is when an organism is entrapped by the resin and then fossilized in a biologically inert environment, and is preserved as a whole. Insects are usually among the most common organism found in ambers. Especially flying insects the land on trees and those found on trees. However, usually all that is found of these flying insects particularly dragonflies is fragments of wings and legs. There are a few samples the contain species from the Odanata order, but not many.
