I was stacking wood, and I saw this large insect on one of the logs. I’m guessing the overall length was about four inches. Does anyone know what it is?
Cool looking bug. I just saw this one.
I think it’s a
That’s it.
As I said, I was stacking firewood. From the Wikipedia article, it sounds like the larvae feed on live trees, while the eggs are laid in ‘felled’ trees. I’m guessing the wood will be OK for firewood. FWIW, the wood came from a maple tree we had chopped down a few years ago.
There’s a lot of termite damage in both the maple, which has been in a stack in the yard until I split the logs last weekend, and also in the cedar logs. (I think the termite damage is what caused the cedar to come down earlier this year. We’re having the rest of it cut down Thursday.) I’ll put out the termite-infested wood so people can take it for camp wood at the beach.
Looks more like an Asian longhorn beetle to me.
… having said that, the Asians look like they have more black on them than yours does, whereas the Alpines look like they have less black than your. Uncertain now.
I think gdave had it.
The elytra are dark with three white bands. The thorax (pronotum) is white with a large black spot. The alder borer’s antennae are banded white and black. The male’s antennae are longer than the body
Three white bands n wing covers? Check. Large black spot? Check. And it looks like a male.
The issue is that the Rosalia longicorn ( Rosalia alpina ) or Alpine longhorn beetle , is a fairly rare beetle that lives only in Europe.
The Asian Longhorned Beetle is on the East coast. Sadly.
If it IS a ALB, and I think that is rather unlikely, call your State Ag dept soonest, if you still live in north Washington state. That would be very very bad.
But since @gdave guess of a banded alder borer , Rosalia funebris , is a local beetle, that is most likely. He is almost certainly correct.
They eat the wood of downed trees so are not a forestry threat.
That one is a leaf-footed bug.
And the one in the OP is not an Asian Longhorned. It is maybe a banded alder borer.
(I found an asian longhorned once in a pallet of goods from China. But it was dead.)
Well, I’m glad it’s not. Glad to be wrong.
Correct! It landed on my table and sat long enough for me to take some pictures. A true bug.
