Your letter to the bugman :  I am an undergraduate at the University of New Mexico and I am currently working in a lab that studies ecological relationships. I am very interested in beetles and I am hoping to do research on them for my master’s. While out doing field work I came across this beautiful guy, I was able to determine that it belongs in the genus Lytta, but I am unable to identify a species. Any insight would be helpful and much appreciated!

Unidentified Blister Beetle

Dear Emily,
Blister Beetles are indeed fascinating.  This does appear to be a member of the genus Lytta, and it resembles the Master Blister Beetle, though it is lacking the red thorax.  The closest match we could find on BugGuide is the Red Eared Blister Beetle,
Lytta auriculata, but we are not convinced that is your species.  Your individual appears to have short, textured, green elytra.

Update:  July 20, 2021
Frequent contributor Cesar Crash from Insetologia believe this might be Eupompha fissiceps which is represented on BugGuide.

I was able to ID this guy as Eupompha fissiceps

Your letter to the bugman:  I found this out my back door on my porch.  Think that it is a longhorn beetle but apparently there are 26000 varieties.
Wondered what variety it is.

Six Banded Longhorn

Dear Pat,
We can’t imagine why you wouldn’t want to browse through 26,000 species of Cerambycids to learn the identity of your endangered Six Banded Longhorn,
Dryobius sexnotatus.  Daniel posted an image yesterday of an individual in Oklahoma that was also submitted on July 11.

Your letter to the bugman:  I found this beetle walking through the grass near the woods in our yard.  It was slow and about 2 inches long.

Buggy Accessory: Reddish Brown Stag Beetle

Dear Jenny,
Your image of this male Reddish Brown Stag Beetle is quite beautiful, but we are obsessed with how effectively you used him as a Buggy Accessory with your gorgeously desiged and rendered tattoos and your perfectly art directed and styled wardrobe.  Thanks for ending our publishing day on such a high note.

Reddish Brown Stag Beetle

Thank you for your kind message. I wish I could’ve kept him as a bug accessory but I thought he’d prefer the wood pile!

Your letter to the bugman:  This was in our house and I think I found it to be a six-banded longhorn beetle. Are they endangered?

Six Banded Longhorn

Dear Joy,
This is indeed a Six Banded Longhorn,
Dryobius sexnotatus, and BugGuide has reports from Oklahoma.  According to BugGuide:  “Uncommon/rare; widely scattered, populations are sparse; listed as rare or threatened by several states, e.g. considered a SGCN by AR, LA, and VA
Dury (1902) noted that D. sexnotatus was once abundant but was even then becoming rare.
Perry et al. (1974) noted a sharp decline in the collection since 1942.

Your letter to the bugman:
I’ve been pulling pigweed for 4 weeks and about 2 weeks ago this mass of beetles show up. Hundreds and hundreds, practically overnight.They don’t bite or sting or eat anything I’m trying to garden. I don’t bother them. 4-5 days ago, I’m weeding and my arm starts to itch drastically. I look at the spot, not a bump, not a rash, but a blister!.Still, no idea as to what. 3 days later, aha moment. Turns out blooming alfalfa and pigweed family are a favorite food of adult blister beetles. Get rid of it and the beetles will eat your garden. YAY! I don’t have to weed anymore! There are over 7,000 varieties. Average behavior, adults live about 3 months June to Aug., lay eggs in the dirt, and the larvae spend the rest of summer, fall, winter and spring eating grasshopper eggs, (sometimes bees if they can find them) and hibernating (? is that the word?) The blister is truly awe inspiring. And, purportedly, 6 grams of dead crushed dried beetles in one serving of alfalfa hay eaten by a horse can kill the horse. Wild Birds find them delicious, (I read). The blistering agent survives to irritate the entire digestive tract in most mammals. They usually survive, but may get sick. I’ve been seeing grasshoppers, so maybe the beetles know something about the future I don’t. They don’t bother me and they eat grasshopper eggs and pigweed! Yay, go blister beetle.

Spotted Blister Beetles

Dear Cathy,
We love, love, love your submission.  It is awesome that you have done so much research in the effort to make your gardening more labor efficient.  Blister Beetles (including the Spotted Blister Beetle,
Epicauta maculata, which is pictured on BugGuide) do have interesting and complex life styles, and many members of the family are able to excrete the compound cantharadin which can cause blistering in human skin and is also the active component in the alleged aphrodisiac Spanish Fly which is made from the ground bodies of a green European Blister Beetle, Lytta vesicatoria.

Your letter to the bugman :  Keep seeing about 5 or more of these things on my porch every night. Never seen them before. In one of the photos you can see in next to the door bell for size reference. It’s quite large.

Male Tile Horned Prionus

Dear Max,
The male Tile Horned Prionus, which is pictured on BugGuide,
Prionus imbricornis, is one impressive beetle.  According to BugGuide:  “larvae feed in living roots, primarily oak and chestnut, but also grape, pear, and corn.”  BugGuide also includes this reader observation:  “On mid-summer nights, these hit lighted windows so hard at my house in Durham, North Carolina, that I fear the glass will break. Seems that mostly males come to lights.”
