Flathead poplar borer2

12th July, 2008. This beetle was emerging from a hole in the tree trunk where it would have spent its time as a larva, probably only recently emerged from pupa.


Flathead poplar borers are some of the larger species of jewel beetles, they have a long point (name?) at the end of their abdomen which is characteristic in Dicerca jewel beetles. Look for these on sunny tree bark and low branches of Aspen poplar and Pine trees. Adult females lay eggs under bark and the larvae (known as Flathead borers, because they are very flat, this makes it easier for larvae to move around) develop and stay in the tree trunks for about 2-5 years, when the adults hatch they use their strong jaws to cut a hole out of the tree to escape from.
