Longhorned Borer Beetle: Parandra polita

Dear James,
This proved to be a bit of a challenge because your beetle does not really resemble other members of its family Cerambycidae, the Longhorned Borer Beetles .  Luckily we identified it as
Parandra polita in Arthur Evans marvelous book Beetles of Eastern North America.  We verified that identification on BugGuide.  According to BugGuide:  “Larvae in heartwood of hickory, tuliptree, beech.”  In his blog Beetles in the Bush, Ted C. MacRae provides this account:  “As I did, I noticed a reddish-brown, large-mandibled beetle sitting on the sheet that, for all intents and purposes, looked like a small stag beetle. I wasn’t fooled, however, as I knew exactly what this beetle was—I had previously seen this species in the form of two individuals at a blacklight in southern Missouri very near to my current location (although it was 28 years ago!). It was Parandra polita, an usual longhorned beetle belonging to the archaic subfamily Parandrinae, and those specimens (MacRae 1994) plus another collected more recently a few miles north—also at a blacklight in wet bottomland forest along the Mississippi River (McDowell & MacRae 2009)—to date represent the only known occurrences of this uncommon species in Missouri.”

My son found this boldly patterned beetle that appeared to be brushed with gold dust on a beech sapling that was covered in fat grubs reminiscent of potato beetle larvae that were eating the leaves. I don’t know if the larvae had anything to do with the beetle itself but I thought it might be worth mentioning even though I didn’t get a picture of them. These pictures were taken at the D.A.R. State Forest on June 28, 2017 in Ashfield, Massachusetts. I scoured all my insect field guides and guides to New England wildlife to no avail. I’ve asked amateur nature buffs and no one has been able to identify this little beauty. My brother suggested asking “What’s That Bug.”
Thank you

Leaf Beetle

Dear N. Gerlach,
This is a Leaf Beetle in the genus
Calligrapha, and many species in the genus look very similar.  Your individual appears to be Calligrapha rowena based on this BugGuide image.  According to BugGuide it feeds:  “on Cornus (dogwood).”

Leaf Beetle

Thank you so much!  I can’t wait to share this identification with my family.

Hi. I saw this beetle in the cloud forest of Ecuador but have been unable to identify it. I’ve narrowed it down to some variety of jewel scarab (Chrysina sp.). Perhaps you could help me?

Scarab Beetle

Dear Camille,
We will post your image of a male Scarab (note the antennae) and attempt to determine a genus and species identification for you.  Perhaps Cesar Crash from Insetologia will recognize this Scarab Beetle.  We looked at the genus
Chrysina on the Generic Guide to New World Scarab Beetles and no pictured individuals have a scutellum shaped like the one on your individual (see BugGuide where it states: “The scutellum typically forms a small posteriorly-pointing triangle at the base of the folded wings”), so we are not convinced that genus is correct.  This image of Calomacraspis haroldi on the Generic Guide to New World Scarab Beetles has a scutellum shaped like your individual.  Following that lead regarding the subtribe Anticheirina, we believe your Scarab might be Dorysthetus taeniata, which is pictured on the Generic Guide to New World Scarab Beetles.

Thank you so much Daniel! You are right about the shape/size of the scutellum. I noticed it but didn’t know what it was called or how to search for that difference. You are probably right about the genus Dorysthetus, but I’m not so sure about the species of Dorysthetus taeniata (at least compared with the photos I can find online). There is a lot of green edging on the scutellum as well as the insect’s nose area and eyes. Also, you can’t see it as well in this photo, but there are 4 light-colored spots along the very back sides. This is close enough for my labeling purposes although if you find out more, I would love to know for sure.
Thanks again!

This guy turned up 3 days ago, didn’t see him yesterday as it rained. He has been in the position on the brick for a number of hours. He has changed direction and as it gets later is no longer noise down. The pictures with the blue background were from 3 days ago. The brick ones are today July 8, 2017 in Swansea, MA we have walked past him numerous times but he has not moved.

Female Broad-Necked Root Borer

Dear Wendleskins,
This is a female Broad-Necked Root Borer, and what appears to be a stinger is actually an ovipositor that she uses to lay eggs.
