The insect order Hymenoptera is one of the most species rich groups of insects, and is traditionally divided into two suborders: Symphyta and Apocrita. The suborder Apocrita includes the well-known wasps, ants and bees, exemplified by traits like stinging, pollinating and eusociality. Symphyta - the sawflies - is a paraphyleticparaphyletic:
describing a group with members arising from a common ancestor, but not including all of the known descendants of that ancestor
group of 14 extantextant:
in existence; opposite of extinct
families that represents the oldest evolutionary branches of the order. North America is home to genera from 12 of those families.
Below are two cladograms to assist in understanding superfamily and family-level relationships within the Hymenoptera:
At this time, Sawfly GenUS does not address genera that occur only south of the United States/Mexico border. This list is adapted from Taeger et al. 2010Taeger et al. 2010:
