Your letter to the bugman:  Thanks for your thread on the CO Glowworm. I found three tonight in the weeds by our home in the foothills SW of Denver. We live at 7000′ just north of Woodland Park, south of Pine, and west of Rampart Range (all places mentioned in the thread.)
We’re new to the area, but none of the long-timers have ever seen anything like this.  I’m fascinated and terribly curious to learn more. Have you found any more info on these guys?
I’m attaching a pretty crappy picture fwiw. My good camera is with my son out of state. If I can find more next week, I’ll see if I can grab better pix.

Firefly

Dear Amy,
Though we would relish a better image of your insect, we do want to commend you on visually capturing both the insect itself as well as its bioluminescence.  Based on your image, which we believe to be of a pink larviform female, we surmise this is a Firefly from the genus
Microphotus, and while BugGuide does not list any sightings in Colorado, there are sightings in California, Oregon, Arizona, New Mexico and Texas, so the range might actually extend to Colorado.  Part of the confusion is that some literature refers to the California species Microphotus angustus as a Pink Glowworm, though it is actually a Firefly from the family Lampyridae.  Since we are constantly trying to clean up our archives, slowly making corrections, we are changing the name of the Glowworm posting you originally cited to correctly indicate this is a Firefly.  As an aside, our editorial staff is currently on holiday in Ohio where we have been enjoying nightly Firefly displays.

Your letter to the bugman:  It flew in a window at night. It seemed to fly awkwardly and made a loud sound when flying. It also seemed to be grooming its antenna.

Ten-Lined June Beetle

Dear Rob,
This is a Ten-Lined June Beetle and they are frequently attracted to lights.  They will also stridulate when handled, meaning they make squeaking sounds by rubbing body parts together.  Just last week, a large male Ten-Lined June Beetle was on the screen door at the What’s That Bug? offices in Mount Washington, Los Angeles.

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?
How you want your letter signed:  Great big bug

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.

Your letter to the bugman:  Hi, my mother found this beetle a few days ago. I cannot find a similar one on the Internet. It was long with large mandibles and scarlet.:  Allnutty

Blister Beetle: Synhoria testacea

Dear Allnutty,
The first thing we have to say is WOW, that is one impressive beetle.  Interestingly, as we began our research, we found this very beetle pictured on the Travel Malawi Guide site, but alas there was no identification.  Though its appearance is not typical of the family, the antennae caused us to ponder if this might be a Blister Beetle in the family Meloidae, and there is one North American species that has a similar large head and mandibles, the Big Eared Blister Beetle,
Cissites auriculata, which is pictured on BugGuide, so we started our more thorough search with the subfamily Nemognathinae.  That led us to the Researchgate and Meloidae of Namibia where Plate #6 pictures Synhoria testacea.  We verified that identification on iNaturalist where there are several wonderful images.  It is also pictured on What Species?
