Cottonwood Borer

Cottonwood Borer

This distinctive beetle, which really resembles no other North American species, is a Cottonwood Borer, Plectrodera scalator.  According to BugGuide, it is in a “monotypic genus” meaning it has no close relatives with which it is classified.

Female Longhorned Borer Beetle

Dear Kristen,
This is a Longhorned Borer Beetle in the family Cerambycidae, and because of the presence of an ovipositor at the tip of the abdomen, we can tell she is a female.  There is not much detail in your image, but the ovipositor is rather distinctive, so we believe based on this BugGuide image, this might be
Graphisurus fasciatus which looks similar and ranges in Ohio.

Hello. I saw this bug on the outside of glass French door the other morning. Now I found him or his buddy under the wheel of the grill on deck, which is located a short distance from French doors. I am watching him now he’s slowly moving back under the grill wheel. Boy I hope it’s not a roach! He’s about 2 inches long

I found this bug dead in the gutter in front of our house. We are in Corona, CA and are backed up to the Cleveland National Forest (5 feet passed our gate ). The weather here has been sunny, low to mid 80s for a few days now. There was a sprinkle of rain a few days ago. I put my foot next to the bug for size reference, it was maybe 2.5 to 3 inches long. What is this thing? It almost looks like a cockroach but I can’t find any that look like this.

California Prionus

California Prionus

Dear Kate,
This magnificent beetle is a California Prionus, and according to BugGuide:  “Adults active summer through early fall; fly at dusk or in the evening.  Food  Larva feed primarily on living deciduous trees (oaks, madrone, cottonwood) and are also recorded from roots of vines, grasses, and decomposing hardwoods and conifers. Will also attack fruit trees growing on light, well-drained soils (e.g. apple, cherry, peach).”  Your proximity to the Cleveland National Forest is likely a factor in your sighting.

Dear Mr. Sam Moore,
We believe that based on the similarity between your individual and this image posted to BugGuide, that you have a female Lesser Pine Borer,
Acanthocinus nodosus.  According to BugGuide:  “Larvae eat bark (phloem) of dead or dying pine. Pupation occurs near bark surface. Adults are attracted to lights.”

Dear Eline en Esra,
Your beetle is a Longhorned Borer Beetle in the family Cerambycidae, and just yesterday we spent about an hour attempting to identify another member of the family from Thailand,
Cyriopalus wallacei, so we knew the best place to start searching for the identity of your individual.  We went straight to the Worldwide Cerambycoidea Photo Gallery and filtered individuals from Thailand, and then on page 3 we found the Common Tuft Bearing Longhorn, Aristobia horridula.
