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.”

it’s a longhorned beetle, but what kind? Dear Bug Person, I found this on a coffee singles package this morning in our warehouse. I live in Spartanburg, SC and cannot tell if this is a Carolina Sawyer beetle or not. It has larger pincers than the sawyer beetle. We do receive foriegn shipments, maybe he hopped a ride overseas?!

Hi Shane,
When we aren’t sure, we turn to entomologist Eric Eaton who usually knows the correct answer. Here is what he has to say: “My best guess is the “spined bark borer,” Elaphidion mucronatum. Those spines on the antennae are distinctive. Certainly that genus anyway.

Hi Janet,
Your beetle is one of the Long Horned Borer Beetles from the genus Megacyllene. Your beetle looks like the Painted Hickory Borer, Megacyllene caryae which closely resembles the Locust Borer, Megacyllene robiniae. The telltale markings of the Painted Hickory Borer include the third stripe on the elytra which is W-shaped followed by three additional sinuous stripes. This species is usually found in the spring, while the Locust Borer is found in the fall. Larva feed on the wood of hickory, ash, hackberry and Osage orange trees.

Hi Angeline,
We thought Eric might be more help with the beetle. I thought it might be a Cerambycid, one of the Long-Horned Borers, but Eric is not convinced. Hope that helps.

Scary Bug
Hello,
Could you please help me to identify this bug I have never seen one of these before. It was on our ceiling and was terrifying my young son (unfortunately the bug didn’t survive). It was about one inch long excluding legs and feelers. I would like to be able to tell my son what it is and whether or not it is harmless. We live in San Diego, California.
Thank you,

Hi Caroline,
The Eucalyptus Tree Borer, Phoracantha semipunctata, is harmless to you, but will do considerable damage to your eucalyptus trees. This insect was introduced to southern California from Australia where it has multiplied due to the absence of natural predators. Young bore into the wood of Eucalyptus trees and have destroyed many stands of this common tree.
