Unknown Longhorned Borer Beetle
Longhorned Borer Beetle is Oedudes species

Hi Fred,
This is such a beautiful Bycid, or Longhorned Borer Beetle in the family Cerambycidae, and we thought it would be easy to identify.  We are troubled that we were not able to find a match on the internet.  Our first lead was this unidentified specimen on Richard Seaman’s FlickR page, but we aren’t even sure they are closely related.  We thought for sure we would be able to identify it on the Cerambycidae de Costa Rica site, but alas, our eyes went blurry we looked at so many photos.  Perhaps eye fatigue caused us to miss it.  Though it looks somewhat similar in markings, the anatomical structural differences don’t quite match on these Crioprosopus nieti we found on the Cerambycidae de Costa Rica site.  The North American Milkweed Borers in the genus Tetraopes that are pictured on BugGuide look very similar in structure and coloration, however the Costa Rican species pictured on the Cerambycidae de Costa Rica site do not look similar.  We hope one of our readers will have better luck with this ID.

Update:  Oedudes species
We received two comments, one suggesting this might be Oedudes bifasciatus and another suggesting it might be Oedudes callizona.  See photos of Oedudes bifasciatus on The Early Birder, on Project Noah and on FlickR and a photo of Oedudes callizona on Cerambycidae Species.

Hi Daniel,
I’m a herpetologist amateur.
I realise that to determinate bugs is very very difficult!
Thanks a lot for the information

You are most welcome Fred.  Your photos are quite lovely.  We have no scientific background and there are no entomologists on our staff, so any answers we provide should be viewed as questionable rather than conclusive.

  1. I suggest that it is Oedudes callizona (Bates). The only image of that species on the Web that I could find is of the type which is old and faded but the swtructure and color pattern are the same.

    • Thanks so much for the identification. We got a second confirmation from another reader on the genus, but not the species. We will attempt to find a link to the photo.
