dog ate it
by: just john

so, standing around one beautiful day in Zig Zag Oregon, summer of 1998, one of these flew up, landed on nearby tree. we checked it out up close - it was gorgeous! about 1 1/2" body, 1 1/2" antennae. when when it flew off (making a loud buzzing racket), my dog jumped up and snatched it out of the air and crunched away, eating the whole thing. weird.

Beautiful Bug!

A customer discovered one of these beetles just outside the door of the Variety Store in Willamina, Oregon today (9/9/11). Quite a beauty!

We spotted a few around our cottage in the Garden Bay Area of the Sunshine Coast. Colorful black and white markings.
This was the first that we noticed this insect in our area.

I was leaving our travel trailer, and just as I hit the bottom step, noticed this odd looking "BUG".
I took a photo and have since, through the wonders of modern tech, discovered what it is.

This beetle did not kill your trees, as you read in the comments about this borer it feeds on dead hardwoods....However, if you have the eastern Asian longhorn beetle it may be the culprit. They do look similar but different.
Please send a photo of your beetle for positive Id.

Beautiful Bug or Not.
by: Anonymous

Although beautiful in color, I have lost around 300.00 dollars due to these beetles. They have been found around my trees only when we would water them. Lost all the trees and beetles were gone. Found two of them the other day around some new trees i have planted. Really concerned now.

Saw one in Rancho Cucamonga, Ca
by: Charles

I worked at an office building that was next door to a tree farm in Rancho Cucamonga, California. I was taking the trash to the dumpster outside and was surprised to see this quite-large insect just sitting on the ground. I was a bit cautious because I had never seen a bug like this before. I showed the picture that I took of it to many people and they were all creeped out by how big it was, LOL. Beautiful insect though.

Joeshwa,
The color difference may not be male/female but how old the beetle is. The longer it lives the more beat-up and dull it would look.
Secondly, the adults feed on nectar or pollen...it is the larva that eat the dead hardwoods.

I need to learn more
by: Joeshwa

I have found and captured two of these beautiful bugs and as far as I can tell either the female or the male not sure which has a brighter white than the other and together can consume phenominal amounts of wood and seem to like mertle wood more than others I would love to learn more about these amazing creatures

As you noticed the adult on dead damaged wood , it was probably looking for a place to lay eggs since the larva feed in dead hardwood.
Great observation.
What a colorful beetle it must be to see!

BLACK & WHITE BEETLE
by: BARB

I live in Ashford, WA ( Foothills of Mt Rainier) I have seen this beetle on occasion in the past. Just a few days ago in Sept. I spotted one a my business in Eatonville WA. It appears to like a spot on the fence where the wood has been damaged. Has been ther now for several days. Great looking bug.

Banded alder borer
by: Moni

This is a banded alder borer. It is found from California and New Mexico north. Larvae feed in dead hardwood trees: maple, alder, oak, willow. These longhorned beetles are confused with the eastern Asian longhorn, but if you look at photos of the two, the banded alder has much more distinct black and white bands while the asian has spots that are not in a certain pattern. They are both in the Cerambycidae or longhorn beetle family
Great photo and what a neat beetle to see on your walk!

black and white beetle, possible asian longhorn
by: Anonymous

The Asian Longhorned Beetle (ALB) is large, ranging from 0.75-1.25 inches long, with very long black and white antennae. The body is glossy black with irregular white spots. These beetles feed on many species of hardwood trees. Adults can be seen from late spring to fall depending on the climate. This beetle was introduced from China and is currently limited to areas within the cities of Chicago and New York.
