One advantage of a point-and-shoot is one-handed snaps as above, a more difficult feat with a heavy SLR. The White-spotted Sawyer Beetle, Monochamus scutellatus (Say, 1824), is probably better known in Alberta as the Tar Sands or Oil Sands Beetle. When a conifer is damaged, a variety of volatile chemicals are released, and sensors in the long antennae allow the female beetles to track down a good tree in which to lay their eggs. The larvae then burrow in the wood for a couple of years. Apparently the tar sands emit similar turpentiny smells and keep the beetles a buzz.
Sawyer beetles are rather large: the White-spotted Sawyer above was about 2.5 cm long with an antennal span of 7-8 cm. I once had a job sawing off all the limbs, one by one, from the ground to the top of live, standing fir trees. I still remember the shock when large sawyer beetles would crash into me while I was dangling 30 or 40 feet above the ground. It did make one appreciate their safety ropes. The beetles may have appreciated the results of our work – a limbless tree that looked more like a telephone pole – but I don’t think the poor poplar branch boring longhorn beetle (Oberea quadricallosa LeConte) above will be able to appreciate much of anything without its antennae. Who knows what disaster befell the beetle, but it may have been ants tending aphids and objecting to its feeding on a poplar leaf. As you may note from the clarity of the picture, this one came from my wife's Nikon SLR.
