Red Milkweed Beetle

Dear Oceangirl,
Was there any milkweed growing near the sighting?  This is a Milkweed Longhorn in the genus
Tetraopes, most probably the Red Milkweed Beetle, Tetraopes tetrophthalmus, which is pictured on BugGuide.

That is awesome, I checked the link…that’s the bug!!
PS I am copying my sister Muzz and her husband Mike on this. They live in the rainforest area in Panama and they have some great bugs there.
Muzz and Mike, I saw a strange bug on my porch today and discovered whatsthatbug.com and the bugman.

Daniel, thank you for this great service!
I’m with you on preserving natural habitats and learning more about bugs.

Monochamus galloprovincialis), also referred to as the Black pine sawyer beetle, is a species of beetle in the family Cerambycidae. It was described by Olivier in 1795, originally under the genus Cerambyx. It has a wide distribution, occurring naturally throughout Europe and the Caucasus.

Your letter to the bugman:  My son found this bug near a creek. It looked dead, as flies were crawling on it. It’s over an inch long.

Cottonwood Borer

Dear Gage,
This magnificent beetle is a Cottonwood Borer, and since cottonwood trees are frequently found near water sources, that would explain the beetles proximity to the creek.  The fly appears to be a Flesh Fly.

Your letter to the bugman:  We found this bug on the porch, our house is in the country on an orchard. I’ve looked everywhere and still can’t figure it out. It’s definitely a big, but I’ve never seen anything like it before. Any ideas?

California Root Borer

Your great big bug is a California Root Borer, Prionus californicus, and according to BugGuide:  “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).”  The antennae on your individual indicates it is a male.  We suspect the porch light attracted it.

That’s completely fascinating! Are they harmful to humans? Will they bite?

They have powerful mandibles and they might bite, possibly even drawing blood, but they are not venomous.

Longicorn:  Trachyderes species

Dear Claudia,
We believe we have identified your Longicorn as
Trachyderes succinctus thanks to images on iNaturalist and Cerambycoidea.  According to iNaturalist:  “This species is present in Argentina, Bolivia, Brasil, Costa Rica, Panama, Colombia, Ecuador, Nicaragus, Paraguay, Peru, Venezuela, Suriname, French Guiana, Brazil, Bolivia and Antilles.” 

Update:  Thanks to an update from Cesar Crash, we believe Trachyderes hermani which is pictured on the New World Cerambycidae Catalog is a better species identification.
