Dear Bugman
I don’t even know if this site is still running or tended regularly, so I will just send this and hope for the best.
I live in Australia, the land of Poisonous Things. I am wary of anything that looks like it might bite me, and this insect has me horrified.
It can fly. It reminds me of a weevil, but bigger – almost as long as an adults thumb. Hard, dark brown, shiny shell with thick legs and antenna. Long body.
And the most awful looking pincer type arrangement at the head.
It looked awful and I had my husband remove it from the house. I have never seen anything quite like it – can you help?
I have attached the clearest picture I could take without getting too close!

Possibly Acacia Longicorn

Possibly Acacia Longicorn

Dear Carly,
This is a Longhorned Borer or Longicorn in the subfamily Prioninae, and we believe, based on images posted to BushCraftOz that it might be an Acacia Longicorn,
Eurynassa australis.  According to BushCraftOz :  “Found under eucalypt bark, with head protruding. Larvae live in dead wood of acacia species. Large beetle ~40 mm.”  Beetles in the family Cerambycidae have powerful mandibles, and large individuals, like the one you found, might deliver a painful bite if carelessly handled, and the bite might even draw blood.  Though a nip might be painful, it is not dangerous as the Longicorns are not venomous.

Hi Daniel
Thank you for the information. I just couldn’t find any details on a native species with such big pincers!
I really appreciate your email, and the time to look into it for me.

Hi there,
I found this bug on our tree in the backyard. It seems to be a bumelia borer, however it has orange-black banded antennae. I could not find another picture like this on the Internet. Is it the same bug?

Longicorn: Litopus latipes

Dear Rachel,
This Longicorn really does resemble the Bumelia Borer.  We first found a matching image on FlickR that was identified as
Litopus latipes, and we verified that identification on Biolib and iSpot.

I found this strange little guy (or gal) in my back yard. Couldn’t figure out what it was even after exhaustive searching (Mainly me typing Furry Ant-Spider Hybrid into various image search engines and forums), hopefully you may recognize it. In terms of size, it looked to me to be about 1cm long. I took pictures from a couple angles, it is a remarkable looking little thing, would love to know what it is! Thanks!!

Furry Bycid might be Lophopogonius crinitus

Furry Bycid is Ipochus fasciatus

Hi Ace,
This is a Longhorned Borer Beetle in the family Cerambycidae, not a Velvet Ant.  The furry covering is quite unusual for the family, but we did post a similarly hairy Bycid from Puerto Rico in January from the genus
Ecyrus.  We searched the genus Ecyrus on BugGuide and found only representatives in Eastern North America, but we expanded the search to include other members of the tribe Pogonocherini and that led to a single mounted specimen of  Lophopogonius crinitus that is pictured on BugGuide.  We also located images of mounted specimens on A Photographic Catalog of the Cerambycidae of the World.  There is not much information on this species online.  We have contacted Eric Eaton to get a second opinion of the identification.  Are you able to provide us with a county or city location?

Possibly Lophopogonius crinitus

Ipochus fasciatus

Eric Eaton Responds
Close.  Sort of.  Ipochus fasciatus:
Nice images considering how tiny.

Thank you so much! It feels so good to finally know what it is hahaha! The location is Santa Cruz, right along the coast, if that helps add to info about it’s geographical spread. Thank you again so much!!

Flatfaced Longhorn

Huisache Girdler

Dear Hannah,
This is one of the Flatfaced Longhorn Beetles in the subfamily Lamiinae, and we will try to determine the species for you.  We will check with Eric Eaton to see if he recognizes you beetle.

Eric Eaton Responds
Hi, Daniel:
Yes, I believe it is the Huisache Girdler:
Species Oncideres pustulata – Huisache Girdler – BugGuide.Net

Ed. NOte:  According to BugGuide:  “Primary hosts:  Leucaena lveruienta – Tepeguaje;  Acacia farnesiana – Huisache;  Albizia julibrissin – Mimosa;  Will also girdle mesquite, retama, ebony and citrus.

We were splitting Madrone firewood today (10/19/14), and it was full of borers of some kind. There were two varieties. The black & green variety was the most common (probably 90%), but there were also some of the red and black. We’re interested in learning more about them, particularly whether they’re a threat to our woods.

Dear Jim,
We believe your Longhorned Borer might be
Neoclytus conjunctus, which is a native species found along the western portion of North America according to BugGuide.  Alas, BugGuide does not offer any specific information on the species.  We suspect it is not a cause for concern as it is a native species.  Your red and black beetle belongs to a different family and we will research its identity later.

This beetle (?) was the largest I saw in Nepal. It’s about 4 inches long and had scary-looking mandibles. Taken in July.

Longhorned Borer Beetle

Longhorned Borer Beetle

Dear Bug Curious,
This is some species of Longhorned Borer Beetle in the family Cerambycidae, and we will attempt to determine the species for you.  Beetles in this family have very powerful mandibles and large individuals might draw blood should they chomp down on a finger.

Dear Daniel,
thanks for the ID on this and the tiger moth. If it helps, here is a link to my a post on my blog with a short film of the beetle.
I posted some random photos of large insects and other creatures I saw while teaching English in a monastery outside Kathmandu. I managed to identify a couple by googling, but some I couldn’t, so thanks for your help! I will update the blog with your information.
