Bug
Found this bug on the dock at our family cottage near Bancroft Ontario. Any ideas?

Oh, the carnage. This is a Sugar Maple Borer, Glycobius speciosus. This beautiful beetle lays eggs in the bark crevices of hard maples and the larvae mine between the bark and the wood.

Unknown Ontario beetles
I’m hoping you can identify these beetles I encountered when I was doing some photography north of Algonquin Park in Ontario. I am equally interested in bugs as I am photography so I am always looking for opportunities to photograph them when I am out shooting.
Many thanks,
Janet Nelson

Lepturine Flower LonghornBlister Beetle


Hi Janet,
We checked with Eric Eaton and he couldn’t conclusively identify your beetles based on the photos, but he did give us Families. One is a Lepturine Flower Longhorn, the one on the daisy, and the other is a species of Blister Beetle.

Ed. Note: We just received this identification.
(08/09/2005) identifications
Hello – I was recently shown your site, and it is excellent. My specialization is longhorned beetles, and in cruising around I notice a number of incomplete or uncertain IDs for this family. I don’t know if you are interested in receiving this sort of input, but if you are, I offer the following additions to your identifications.
The lepturine cerambycid is Strangalepta abbreviata, a common eastern species which frequents a variety of flowers as an adult. The larvae typically breed in decaying wood. Keep up the good work. You are a valuable resource. Cheers Frank Hovore

I can’t find this bug in your pictures
We found this gorgeous bug on a piece of wood from a mesquite tree that had been recently cut down in our son’s yard in Saint Hedwig, TX. It is just east of San Antonio. We usually take pictures of neat bugs and love your web site. Any help would be appreciated.

Hi Muriel and Tom,
We actually do have a photo of this particular beauty on our second beetle page from 2004, but it was unidentified. This predates our collaboration with the awesome Eric Eaton who usually manages to identify everything we cannot. Here is his response when we asked him if he recognized this gorgeous green Cerambycid: “Yes, I do! It is Plinthocoelium suaveeolens. I almost caught one in southern Missouri, but it got away:-( Larvae bore in the trunks and roots of tupelo and mulberry trees. Eric”

what is it …
and why did it fly into my kitchen window at dusk? It looks like some cockroaches I saw in Baja many years ago, but I’ve never seen anything this big here just south of San Francisco.
Thank you.

Hi Lynn,
You have been visited by a Pine Sawyer, Ergates spiculatus, also known as the Spineed-Neck Longhorn. Larvae eat the sapwood and heartwood of pines and Douglas firs and adults emerge July – August. I guess the rains brought them out a little early this year. Females are often attracted to lights. Their habitat is usually forests near and above 4000 feet. According to Hogue: “campers in pine flats in neighboring mountains are frequently startled when these beetles loudly buzz into their lanterns on warm summer evenings.”

What is this bug???
Someone posted a picture of this bug on an online forum I am part of and I’m so intrigued with it, I have to know what it is. It is on a door and looks to be quite big, possibly 6-8 inches long. I’ve searched on the net for a while, but not knowing anything other than it is an insect, hasn’t helped me find anything on it. Hopefully you can lend some insight as to what it is. I believe it was found in Buffalo, NY. Doing a little more investigation, I guess the bug in the picture is the size of a quarter (just a really big zoom). I’d still like to know what it is if you could. Thanks.

Hi Jordan,
Your beetle is a Round-Headed Apple Borer, Saperda candida, from the Family Cerambycidae. In the larval stage this species is very destructive to apple trees, quince and a few other species.

What is this?
I am finding these in my garage. The only place I can think that they are coming from is some fire wood I have stacked in there from over the winter. I didn’t really use the wood stove all that much and most of the wood is still there that I put there at the start of last summer (2004). If these are coming from the wood why did they not come out last summer?

Hi Steve,
We contacted Eric Eaton to share his thoughts on your Borer Beetle. Here is his response: “Decent image of what might be the Tanbark Borer, Phymatodes testaceous. Certainly something in that genus. The tanbark borer is supposedly common in eastern North America, but is also found in Europe and northern Africa! Adults vary from 8-17 mm. Larvae bore in the wood of dead and dying hardwoods, and also pine.”
