I found this bug trying to crawl throw my open back door in Pattaya, Thailand.
I think it is dying as its movement is very laboured (just flicking its legs and ‘wings’ if that is what they are) I have a huge jackfruit tree in my back garden so was wondering if that is what attracted it in the first place
Thanks

Hi there, just thought you might like to see this bug I found. from what i can find its a arcacia longicorn beetle. Is this correct. I am currently living as care taker on a block of land on the edge of Whyalla South Australia. It is a prime reserve of thick Mallee scrub. We always get a huge variety of unusual animals and insects.

Acacia Longhorn

Dear Darren,
We had a slow day today with not many submissions, so we went back a few weeks to some unanswered requests, and we are thrilled to find your Acacia Longhorn,
Penthea solida, submission.  We only have one image of this species in our archives and your image is of a much better quality.  There is a very nice image of the Acacia Longhorn posted on Cerambycoidea.com.  There is not much information on this beautiful beetle online but there are some images on FlickRiver.

Hi we have these in our house occasionally, we think they are coming in on our firewood. The wood is ash and oak. The house is only a year old and was built in the winter

Longhorned Borer Beetle:  Sarosesthes fulminans

Longhorned Borer Beetle: Sarosesthes fulminans

Dear Keith,
We turned to our copy of Arthur V. Evans excellent book “Beetles of Eastern North America” as it is easier to scan than many online sources.  We believe we have correctly identified your Longhorned Borer Beetle in the family Cerambycidae as
Sarosesthes fulminans which is described as having:  “a distinctive eyespot on the pronotum and angulate bands on elytra.  Larvae tunnel under bark and in sapwood of hardwoods, especially chestnut (Castanea), oak (Quercus), and walnut (Juglans).  Adults are attracted to light and bait traps in late spring and summer.  Quebec and Ontario to North Carolina, west to Minnesota, Iowa, and Kansas.”  This image from BugGuide looks very much like your individual.  You are most likely correct that your indoor, winter sighting is related to oak firewood.

Hi, I’d like to identify this little guy for peace of mind – he was in my baby’s play room (and inside my shirt) and I’d like to know that he wasn’t poisonous. I threw him unceremoniously outside.

Longhorned Borer Beetle

Longhorned Borer Beetle

Dear Jessica,
There is not enough detail in your image to identify this beyond the family level.  This is a Longhorned Borer Beetle in the family Cerambycidae, and it is not venomous.  Members of this family spend their larval stage boring in wood, and they need strong mandibles to chew their way to the surface after maturity, so they are capable of delivering a painful, but not generally dangerous bite.  Large individual might even draw blood.  Individual found indoors frequently emerge from firewood that was brought inside.  They will not infest the wood used in the construction of a home, so they pose no threat to your home.

Acouple of days ago I lift the door open while letting in some cool air, and I didn’t really pay attention and make sure no bugs came in. Then just recently I noticed this bug and I think it looks like a cockroach, it has antennas and has 3 legs on each side with patterns on the back.

Mesquite Borer

Mesquite Borer

This is not a Cockroach.  It is a Mesquite Borer, Placosternus difficilis, a beetle in the Longhorned Borer Beetle family Cerambycidae.  According to BugGuide:  “Larval hosts: Prosopis, Acacia, Pithecellobium, Platanus, Citrus, Leucaena” and “Adults are active day and night, running rapidly along freshly cut branches of their host plants and feeding on the blossoms of Koeberlinia, Acacia, Baccharis, Bumelia, Clematis, and Solidago.”  BugGuide also notes:  “Adults come to lights and bait.”  So, we surmise that either you had firewood from one of the host plants in your house and this beetle emerged from the wood after metamorphosis, or you have at least one host plant growing in your yard or nearby and that the beetle was attracted to the light emanating from the open window.

My brother found this in his house in Minnesota (US) in January. There were about a dozen in the windows. It has yellow striped wing covers. I am sorry about them being slightly crushed.

Longhorned Borer Beetle, genus Neoclytus

Longhorned Borer Beetle, genus Neoclytus

Dear Peter,
Despite their appearance, these are not wasps.  Many harmless insects including some Moths, Hover Flies and some Longhorned Borer Beetles mimic stinging wasps for protection.  Your Longhorned Borer Beetles are in the genus
Neoclytus, and they might be Red Headed Ash Borers.  We suspect your brother brought some firewood into the house and the warm, indoor temperatures caused the adult beetles to emerge early.  They will not damage the home.  You can read more about the genus Neoclytus on BugGuide.
