Just wondering if you can tell me what this bug was. It was So pretty….

Eucalyptus Borer

Dear Tammara,
While it appears to have met an unnatural end, your indication that “It was So pretty” causes us to speculate that you were not involved in this beetle’s demise.  Though it is an insect native to Australia, most of our images of Eucalyptus Borers are sent from Southern California where the beetle has naturalized because of an accidental introduction in about 1967.  There are many eucalyptus trees in Southern California, so when the Eucalyptus Borer was introduced, it had no trouble finding a food source.  According to Oz Animals:  “The larvae of the Eucalyptus Long-horned Borer attack Eucalypt trees. They mostly attack stressed or damaged trees. Evidence of borers includes holes in the bark and oozing fluid on trunk or branches. In severe cases foliage may wilt and limbs die back. They rarely kill healthy trees.”

Longicorn: Dorcadion (Cribridorcadion) decipiens

Dear RS,
Your global coordinates indicate this sighting was made in Romania.  This is a Longicorn in the family Cerambycidae, and we quickly identified it as
Dorcadion (Cribridorcadion) decipiens thanks to Cerambycidae where it indicates the distribution is “Hungary, Romania, Serbia, Monte Negro, Moldova.” 

Dear Daniel,
Thanks a lot for the answer and for Dorcadion (Cribridorcadion) decipiensc identification, which were a big help for me.

Unknown Longhorned Borer Beetle

Dear Helaine,
This is a Longhorned Borer Beetle in the family Cerambycidae, and it looks like the same species Daniel frequently sees at the porch light, but he has not yet identified the species.  Now that your request has arrived, Daniel will spend more time researching its identity.  Based on this BugGuide image, it might be
Paranoplium gracile.  The images of the species on Cerambycidae Catalog appear very different, and look much smaller than the species Daniel has seen.  The species Daniel has seen looks more like Haplidus testaceus which is also pictured on BugGuide.  It is also pictured on Cerambycidae Catalog.

Your letter to the bugman:  I know you already have a lot of locust borer pictures, but thought, since your description in one of the pictures starts with “Adult Locust Borers are often found on goldenrod in the autumn”, you would like to see this shot of one sitting in the goldenrod we spotted while we were out walking the dogs….

Locust Borer

Dear Pat,
We love your image of a Locust Borer on goldenrod and we are thrilled to post it, especially as we just posted another image of a Locust Borer from Washington state, not part of its native range, an expansion made possible because of the cultivation of black locust trees for landscaping and other reasons.

Your letter to the bugman:  Hello, we found this inch-long beetle on a lemongrass plant in our yard.  It’s not in any of our guidebooks.  What is it?

Locust Borer

Dear Beetle-befuddled,
This is a Locust Borer, and if your guidebooks are Pacific Northwest local, and not published very recently, they probably don’t include this distinctive beetle because it has recently expanded its range of eastern North America because of the cultivation of its host tree, the black locust.  According to BugGuide:  “Previously confined to the native range of Black Locust in the northeast, it has spread with the trees throughout the US and parts of Canada. Black Locust is used for reclamation and similar projects where trees are likely to be stressed and thus more vulnerable to damage.”
