Hi there
Can you please advise what species is this ?
It was seen in the Serra dos Órgãos national park in Rio de Janeiro state Brazil.
I was fascinated by the way the antennae were laid across the back and was unable to find anyone that could identify it.
Your assistance would be greatly appreciated.
Many thanks

Double Crested Longicorn

Dear Séamus,
This is an unusual double crested Longicorn in the family Cerambycidae, and we eventually located it on Insetologia where it is identified as
Hypselomus cristatus.  Additional images can be found on Cerambycidae of the World.  According to Oncid ID:  “The combination of the following characters will help to distinguish this genus: large eyes; narrowly separated antennal tubercles, contiguous at base; bowed scape, gradually expanded to apex; and base of elytra with two longitudinal, arcuate, strongly elevated crests, each crest studded with several round, shiny tubercles.”

Greetings! If you could I.D. the attached bug, I would deeply appreciate it, as these manaical carnivores are rampaging throughout my house! I stuffed one in a jar, and it ate an entire snack bag of sweet pork jerky. I’m afraid I’m next on the menu. Thank you in advance for your efforts.

Dear Suzanne,
This is a Prionid in the subfamily Prioninae.  It resembles 
Dorysthenes (Paraphrus) granulosus which we found on the World Wide Cerambycoidea site.  They are not maniacal carnivores, though the mandibles of large individuals might deliver a painful bite.

We found a bright beetle in our backyard. Our mom tried to look it up but couldn’t find an answer for sure. We think it is a wasp mimic beetle but we aren’t sure. Please help! 🙂

Locust Borer

Dear Jack and Archie,
You are correct that the Locust Borer is an effective mimic of stinging Yellowjackets.  The larval host tree is the black locust, which is native to the North American northeast, but with the planting of black locust trees in other locations, including Washington, the range of the Locust Borer has expanded as well.  According to BugGuide:  “Considered a serious pest of Black Locust trees; previously weakened or damaged trees are often killed by an infestation of the larvae. Previously confined to the native range of Black Locust in the northeast, it has spread with the trees throughout the US and parts of Canada. Unfortunately Black Locust is used for reclamation and similar projects where trees are likely to be stressed and thus more vulnerable to insect damage.”

Over the summer, I found this really neat bug. I have no clue what it could be called, but it sure did like hanging around the nature park’s garden!

Red Milkweed Beetle

Dear Mark,
Though it was on grass when you took the image, this is a Red Milkweed Beetle or Milkweed Longhorn in the genus
Tetraopes, which is always found in association with milkweed, its sole food plant.

we found this beetle on the side of our house on Sept. 7, 2017. I tried to identify it and from what I was able to find, it appears to be a Palo Verde beetle, but that doesn’t make sense as I live 3 states away from Arizona. Please help identify this beetle.

Ponderous Borer

Dear Mike,
You were on the right track.  Both your Ponderous Borer and the Palo Verde Root Borer are in the same subfamily, Prioninae.  See this BugGuide image for comparison.  Of the Ponderous Borer, BugGuide states:  “larvae chiefly in ponderosa pine and Douglas fir.”

My 6 year old found this dead beetle in my mothers succulent garden. What is it? Sorry he is missing an antenna.

Male California Root Borer

Dear Jennifer and Harrison,
This impressive beetle is a male California Root Borer, and males of the species have much more exaggerated antennae than the female.  The female releases pheromones and the male locates her with his antennae.  According to BugGuide citing Evans & Hogue:  “Adults:  Robust, reddish-brown to almost black; Three sharp spines on each side of pronotum; Saw-toothed antennae with 12 segments (scape, pedicel, and 10 flagellomeres…pedicel very short, 1st flagellomere longest, then decreasing in size apically).  Males with antennae distinctly sawlike, more than 2/3 length of body.  Females with more slender antennae, about 1/2 length of body.” 

Thank you Daniel for the identification.  He is now apart of our bug collection:)  Take care.
Jennifer Diaz and Harry
