This is a family tree that shows the way in which Idaho's eight dragonfly and damselfly families are related to one another.  Scientists refer to this type of family tree as a cladogram.  A cladogram is a way of demonstrating our current understanding of the evolutionary relationships of groups of organisms.  This dragonfly and damselfly cladogram is built on our knowledge of the physical and genetic traits of these families.
