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:  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 :  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.”

Your letter to the bugman:  Found this bug on my back porch at night under a light. Had some scary looking chompers. Can you identify?

Hardwood Stump Borer

Dear Anthony,
We feel confident that this is a Hardwood Stump Borer,
Mallodon dasystomus, which is pictured on BugGuide.  According to Beetles of Eastern North America by Arthur V. Evans:  “Mandibles nearly horizontal” while of the similar looking Live Oak Root Borer, Archodontes melanoplus, the author writes:  “Mandibles nearly vertical.”

Purpuricenus humeralis

Dear Dave,
Though this Longicorn superficially resembles both the Red Shouldered Pine Borer and the Elderberry Longhorn
Desmocerus aureipennis, it is a species of Purplescent Longhorn, Purpuricenus humeralis, with no common name that we found on BugGuide.  Interestingly, in doing the research for your posting, we found Purpuricenus humeralis incorrectly identified as a Red Shouldered Pine Borer twice on our site, here and here, and we have made the necessary  corrections.

Your letter to the bugman:  Hello,
I noticed this strange creature on the beach the other day, maybe not even a bug but possibly it is. It was on the beach in the evening, mid June. Quite big in size, about 6-8 cm.
I’d appreciate if you could help identify it.

Great Capricorn Beetle

Dear Elena,
This is a Longicorn Beetle in the family Cerambycidae, and we believe it is
Monochamus sartor.  According to Cerambycidae, the range is “Albania, Austria, Belarus, Bosnia and Herzegovina, Bulgaria, Croatia, Czechia, France, Germany, Hungary, Italy, Montenegro, Norway, Poland, Romania, Serbia, Slovakia, Slovenia, Sweden, Switzerland, Ukraine.”  It is also pictured on BioLib.

Dear Daniel,
Thank you very much for the reply and clarification.
Have a wonderful day!
Elena Romanova

Thanks to a comment from Ando Vaan, we are updating the posting.  We originally considered that this might be a Great Capricorn Beetle, Cerambyx cerdo, but we thought the body on the pictured individual looked too broad.
