Hello all,
Here is a Poplar Borer (Saperda calcarata) I photographed last July 26th, 2009 at Sherbrooke, Quebec, Canada.
This is a quite big bug and was very fascinating to observ. I was able to get this picture with my bridge Panasonic FZ-20. I had to wait until he decided to take off!
Thank you for your comments :)

Swollen bark areas, sap run and piles of frass around the entrance to galleries near the base of the trunk and the roots are signs of the poplar borer’s presence. Bark swelling caused by larval activity is more visible in young poplars. The insect prefers trees with a diameter just over 10 cm, in low density stands.
The insect has a long life cycle, extending over 3 to 4 years. The adults feed on the foliage and the tender bark of twigs. The females lay their eggs in slits they have cut in the bark. After hatching, the larvae begin feeding in the cambium and then penetrate into the heartwood by creating deep galleries. In the spring of the last year of larval development, the larvae change into pupae and then into adults.
The poplar borer is a species native to North America. It is found throughout the geographic range of poplar in Canada and the United States. The borer usually attacks poplars growing on poor sites.
