I found this bug on my car window one evening after coming home. It looks like a stink bug but it has a long stick looking thing on its back end. I’m always interested in researching new bugs when I find them. What is it?

White Oak Borer, we believe

Dear Brooks family,
You are correct that this is a Borer Beetle, and it is a Flatfaced Longhorn in the subfamily Lamiinae.  We believe we have correctly identified it as a White Oak Borer,
Goes tigrinus, thanks to Arthur Evans excellent book Beetles of Eastern North America, and we verified that by matching your individual to this BugGuide image.  According to BugGuide:  “Widespread, but uncommon in e US (TX-FL-NY-MI)” and “Very uncommonly collected although widespead and reportedly an important pest of all oaks in the white oak group.”

Aloha from Hawaii. I live in mililani on oahu and found this really neat guy on my trash can. He is about half an inch long and really strong. I had a really hard time removing him from the trash can and transferring him to a tree. I have lived here 25 years and never seen this insect before. Please can you identify him. I thought he might be a longihorn type of beetle.
Much mahalo!

Dear Jenz,
Like so many creatures found in Hawaii in the 21st Century, this Longicorn is probably an introduced species.  We believe we have correctly identified it as
Coptops aedificator thanks to Cerambycoidea which lists the range as “Arabia, Africa, S. Helena, S. Thomé, Cabo Verde, Madagascar, Comores, Seychelles, Mauritius, Ceylon, India, Andaman. Introduced in China (Taiwan) and Hawaii.”  It is also pictured on Forestry Images where it is identified as the Albizia Long-Horned Beetle, and iSpot.


Mahalo for taking time out of your day to identify him.  We also have Madagascar stick bugs here.  We live on the rim of a nature reserve and find many different insects here. There may be more pics in the future. Aloha jenz

I saw this bug while working this morning, June 23rd in Melbourne, FL. His antennae are so long and is very interesting looking. I tried looking him up online but couldn’t find a similar picture. I was wondering if you had any information as I could not find any.
Thank you,

Is this a milkweed beetle?

Mating Milkweed Longhorns

Dear LALehner,
These are indeed mating Milkweed Longhorns in the genus
Tetraopes, most likely the Red Milkweed Beetle, Tetraopes tetrophthalmus.  According to BugGuide, they can be identified through a:  “combination of broad, disk-shaped hump (callus) on pronotum, strong elytral spots, especially the broad subhumeral spot, and unringed antennae are distinctive for this species.”
