Is the beetle in the attachment some sort of blister beetle? What is it?

Brown Prionid

Dear Dave,
This is not a Blister Beetle, and we do not believe any Blister Beetles attain this size.  This is a Brown Prionid, one of the Root Borers in the subfamily Prioninae.  According to BugGuide:  “Breeds in poles, roots(?) in contact with wet ground.”

Dear Bug man,
I opened my front door this morning and this bug flew in me and would not let go.
It took great efforts to remove it. It is very strong yet intends no harm.
What is this bug?
Does it have any spiritual significance.
Look forward to hearing from you.

Longicorn: Derancistrus lineatus

Dear Empress Sefiatu,
Upon looking at the two images you attached, we could not help but notice the incredible quality difference, and then we noticed that the high resolution, very detailed image had a scientific name as the file name.  We searched that file name and found the identical image of
Derancistrus lineatus on the Mecyme wordpress blog.  Alas, we cannot post images pilfered from other websites.  It seems you have already identified this gorgeous Longicorn as Derancistrus lineatus, and we do not know if it has any spiritual significance, though we tend to reserve spiritual significance to the subjectivity of the individual.  Many specimens on the New World Cerambycidae Catalog, where it is identified as Elateropsis lineatus, were collected on Cuba and the Bahamas.  Prioninae of the World lists the distribution as “Cuba, Guadeloupe, Jamaica.”

Female Root Borer

Dear MeriLowry,
This looks to us like a female Root Borer in the genus
Prionus, and Prionus heroicus which is pictured on BugGuide is a good possibility.

I was walking by dog in the backyard and we have woods, pond, and bogs right in our backyard. I saw this walking on the ground. What is it??

I was hiking up to sentinel dome when I noticed this beetle resting upon this grouping of small flowers. I cannot seem to to find this type of beetle on any identification chart.
Signature: I’m not sure what this means

Flower Longhorn

This is a Flower Longhorn in the subfamily Lepturinae, but we have not been able to quickly identify the species.  We are posting your submission as unidentified and we will continue to research this matter.  Perhaps one of our readers will be able to comment and provide an identification.

Ed. Note:  Thanks to Cesar Crash of Insetologia who identified Lepturobosca chrysocoma for us.  According to BugGuide:  “The very dense, appressed, metallic golden pubescence is distinctive” and “Larvae eat decaying wood, both hardwoods and conifers.”

I found this beauty on my screen porch after a rain, it is about 1.5 inches long with the most interesting antennae. I cannot find a decent key that tells me more than that it is a beetle which I guesses. 71degrees F suburban piedmont NC Semi-wooded lot next to pasture land.

Tile Horned Prionus

Dear Debi,
The spectacular antennae identify this as a male Tile Horned Prionus, and according to BugGuide:  “Huge longhorn, dark brown and shining. Antennae have 18-20 overlapping segments (male).  Female has 16-18 serrated segments. Other eastern Prionus have 12-13 antennal segments.”  BugGuide also states:  “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.”
