Monday I tried to befriend this beetle who was on the floor of the bus (and get her out of the aisle somewhere safer and eventually outside) but she did not appreciate being held, escaped repeatedly and once pinched me before hiding under the wheelchair ramp. Calosoma sayi per iNat.
Large black beetle with longitudinal striations on its wings held on pinkish fingertips.

My third PhD chapter to get published (one more to go!!!). This project examined the biogeography and divergence estimates of Calosoma (Carabophanus) gestroi from the Ethiopian Highlands. We used HyRAD-X to recover genomic markers mostly from fresh specimens.

Orogeny of Ethiopian sky islands and Pliocene climate shifts promoted budding speciation and complex admixture in flightless Calosoma ground beetles
Abstract. Flight loss, through its effect on the resulting dispersal capacity and gene flow, has been proposed as a driver of diversification. Ground beetl

The rainbow one is a ground beetle in the genus Calosoma (Carabidae) and the other is a prionine longhorn beetle (Cerambycidae, something close to Mallodon). Good beetles 👍

"First report on the edibility of X" is an incredibly powerful paper title (more so when you see what they're talking about)
"First record of the edibility of Calostoma cinnabarina" by Bautista-Nava and Moreno-Fuentes (2009) close-up photo of the mature fruiting body of Calosoma cinnabarinum, the "stalked puffball in aspic" that is not actually a gasteromycete, by inat user alan_cruz. It looks like a red, not too threatening fruit of some kind, surrounded by an incredibly suspicious mass of greenish-gray slime wads

it thinks they are a fiery searcher (Calosoma scrutator) but it just knows it was really pretty and was waiting for it to see after its lunch break

Another chapter of my thesis is out!
We used genomic data generated from across the range of the Western Balkan highland endemic beetle Calosoma pentheri support the recognition of two distinct species. Biogeography, divergence estimates, phylo & population genetics, etc.

Good Monday morning. It's now 7:34 a.m. & 43°F outside, with a pale blue sky.

My daily post today, from my "Insect" files, features a photo of a large, metallic green ground beetle know as a Fiery Searcher (Calosoma scrutator).

Continuing the #invertefest #beetle goodness, I present the ridiculous #shiny goodness that is Calosoma scrutator, the Fiery Searcher, a voracious and helpful garden predator.

A macro photograph of a shiny green and darkly iridescent ground beetle hanging out at the edge of a sheet covered door. The beetle's legs are black with a purplish sheen. It's head and pronotum (The area just behind the head) is black with an oil-like rainbow sheen. The elytra, the hardened forewing is bright metallic green. A photo of the beetle from above. Its legs spread wide, its head and pronotum glistening with oil-like dark rainbow iridescence, its elytra a stunning metallic green with a thin line of red along its edge. A close up photo of the beetle's head showing it's powerful crescent shaped mandibles, its glossy black hemispherical eyes and the rainbow iridescence along the edges of its head and pronotum.

found this Fiery Searcher(Calosoma Scrutator)carcass on a walk this evening. i never see beetles this big in kansas! wish it was alive when we met but sadly it was ant dinner.
macro photograph of an iridescent beetle carcass missing it’s head on a green leaf. there is an ant crawling around on it’s thorax. macro photograph of an iridescent beetle carcass missing it’s head on a green leaf. this photo shows the back of the beetle macro photo of the underside of the beetles abdomen. it is segmented and rainbow iridescent. missing legs and laying on a green leaf. macro photo of the iridescent beetle carcass on a leaf, an ant is showing interest.

Today's new friend: this very impatient fiery searcher (𝘊𝘢𝘭𝘰𝘴𝘰𝘮𝘢 𝘴𝘤𝘳𝘶𝘵𝘢𝘵𝘰𝘳).
An iridescent green beetle approximately one inch long, sitting in my hand.

Carnivorous insect larvae are all extremely cool looking, and they deserve to be celebrated more in our culture.

A photograph of the side of the head and forebody of a brightly colored beetle resting on a white sheet. The beetle's narrow head and pronotum (the area just behind the head) is brightly iridescent like an oilsheen, dark in the middle, rainbow at the edges. The elytra, the hardened forewing characteristic of beetles can just be seen on the left and is bright metallic green.
