There are 1,500 known species in North America. They range in size from 25-60mm and are brightly colored.They are also known as “sawyers” because the adult beetles leave piles of sawdust when they burrow out of a log. They overwinter as grubs, AKA larvae, inside the trees.
If you pick up one of these beetles, they will make a squeaking sound and they are good at playing dead; they are also active fliers and runners. The larvae primarily feed on dead and decaying wood but can be destructive in living trees; a few live in the stems or roots of herbs. Adult beetles feed on leaves, fungi, bark, sap, fruit, or flowers. The exotic species of this beetle are outpacing the native species. A study from Canada shows the 30 of the 214 known species haven’t been seen since 1950; habitat destruction is the cause.
