Hi – we spotted this beetle on our van while stopped on the roadside in Algonquin Park in Ontario, Canada last summer (July 1st, 2011).
At first, we thought about the Asian Long-Horned beetle, but checked out pics of the ALHB and saw some significant differences (white spots, etc.)
The roof rack doesn’t help much to demonstrate scale but, as I remember, this guy was about 1.5 – 2 inches long (head to tail), and the antennae were at least 3-5 inches long.
No idea what the red dots are on the beetle, but they look as though they aren’t a part of him…
Can you help us identify this one?
Your large beetle is one of the Longhorned Borer Beetles or Longicorns in the family Cerambycidae, and it is in the same family as the Asian Longhorned Beetle, but your individual is a native. We posted a letter last year of another White Spotted Sawyer from Canada and at that time we identified the hitchhikers as Phoretic Mites. Here is a link to that posting.
