Small Mulberry Borer

Dear Sarah,
This is one of the Longicorns or Long Horned Borer Beetles in the family Cerambycidae, and after a bit of searching, we are confident we have correctly identified it as a Small Mulberry Borer,
Dorcaschema alternatum, thanks to images posted to BugGuide.  According to BugGuide, the larvae feed on:  “Dead or dying branches of mulberry, osage orange.”  Some members of this family are attracted to lights.  In any case, we believe it accidentally entered your bed and it was not there for any nefarious purposes.  Many members of this family are also capable of making squeaking noises by rubbing parts of their bodies together, a phenomenon known as stridulation.

Dear Paul,
This is a Longicorn or Longhorned Borer Beetle in the family Cerambycidae, but we have not had any luck identifying the species.  Larvae of beetles in this family are wood borers.



Subject:  I’m resending bald-face hornet girdling gridwork on bark.

Your letter to the bugman:  I sent this about a week ago and got the confirmation e-mail and I realize you can’t post everything. I did kinda wonder if the picture came thru as I’m on Windows 7 and I’ve had problems with the upload before. So, just checking. I was told BF hornets did it. I thought, Makes sense, thy use the bark to make their paper nests. Then I looked it up! I read they do it to make the sap run and then they eat it! They are “vegan?” and only gather insects and B-B-Q (haha) to provision their babies. Apparently they can girdle a tree, but this pattern leaves bark and cambium to continue the sap flow. Can you verify this behavior? Or if something else did, do you know who? I don’t think it’s our red-naped sapsucker, they leave a grid work of little round drilled holes, and they’re the only sapsuckers we have. Thanks.

Did Hornets damage this tree???

Dear Cathy,
We cannot confirm that Hornets damaged this tree, but if your theory is correct, they should revisit the site to feed.  We have images on our site of European Hornets (introduced to eastern North America) stripping the bark off of lilac bushes.  We will attempt further research into this matter.

Your letter to the bugman:  I was fishing a larger river and went up to the road and noticed these bugs all over the place. They were smashed on the road and were trying to cross the road, from river bank to cornfield and vise versa. The bugs were between 3 and 7 inches long.

Hi Joey,
Did you catch many fish?  If not, nature provided you with an excellent bounty to change your luck.  The Hellgrammite, the larval form of the Dobsonfly, is a prized bait among freshwater anglers.

I knew they looked like hellgramites, but I didnt know they ventured out of the water like they did. Cool thank you for the quick reply.

We believe they leave the water to pupate.

Your letter to the bugman:  Dear Bugman,
I found this beautiful beetle in the rainforest of the Tambopata reserve in Peru. On the web I found similar ones named Pleasing fungus beetle. But I did not find this specific one. Can you help to identify it?

Leaf Beetle

Dear Gerhard,
Though we have not had any luck with a species identification, we can tell you this stunning beetle is a Leaf Beetle in the family Chrysomelidae.  We are confident we (or one of our readers) will be able to provide a more specific identification soon.

Leaf Beetle

Dear Daniel,
thank you very much, lets see, if someone has additional information.
All the best and thanks for your help again.

Update:  July 1, 2019
Thanks to a comment from Cesar Crash, we are confident this is Platyphora princeps.  The images on PicClick are of dead specimens and they lack the bright colors, but they appear to be the correct species.
