Glassy Winged Sharpshooters

Dear Won Cho,
You have two different insects here, in different orders.  Two of them are Glassy Winged Sharpshooters that feed by sucking fluids from plants, and they do the most damage to new shoots.  According to BugGuide:  “A major vector of Pierce’s disease on grape. Usually not a serious pest within its native range, southeastern US. This species was accidentally introduced into so. California in the early 1990s, probably with ornamental or agricultural stock. There, it has become a serious threat to viticulture.  The biggest problem is that it can spread the disease-causing bacterium Xylella fastidiosa.”  According to the University of California Integrated Pest Management System site:  “The real problem associated with glassy-winged sharpshooter, however, is that it can spread the disease-causing bacterium Xylella fastidiosa from one plant to another. This bacterium is the causal agent of devastating plant diseases such as Pierce’s disease of grape, oleander leaf scorch, almond leaf scorch and mulberry leaf scorch. Other diseases to landscape plants in California include sweet gum dieback and cherry plum leaf scorch. Outside of California, other strains of X. fastidiosa cause phony peach disease, plum leaf scald, leaf scorches in sycamore, elm, maple, and oak,and variegated citrus chlorosis, but these diseases have not been detected in California. It should be noted that the strain of X. fastidiosa that causes oleander leaf scorch will not cause Pierce’s disease in grapes and the strain of X. fastidiosa that causes mulberry leaf scorch does not cause disease in oleanders or grapes. At this time there is no cure for any of these diseases.”  The other insect we can only identify to the family.  It is a Metallic Borer Beetle in the family Buprestidae, and the larvae bore in the wood.  They are generally very host specific.  Telling us what tree is affected may help in further identifications.

I found this beautiful beetle crawling on my windowsill. I’m located just outside of Seattle, WA and found him in June. I love the iridescent colors on his back. Please tell me what he is

Dear Melissa,
This is one of the Metallic Borer Beetles or Jewel Beetles in the family Buprestidae.  We have identified it as the Eastern Poplar Buprestid,
Poecilonota cyanipes, thanks to BugGuide images.  According to BugGuide larvae bore in poplar, locust and willow trees.

Dear Sue,
This positively gorgeous Metallic Borer Beetle or Jewel Beetle from the family Buprestidae is aptly called a Golden Buprestid,
Buprestis aurulenta.  Developing larvae have their normal life cycle interrupted when the trees they are boring in are cut and milled.  The larvae seem to go into a suspended animation and emerge many years later.  We created a posting of a Golden Buprestid that emerged from a pine cutting board after eight years, and the record is allegedly 51 years.

Hello Bugman
I found this beetle in central Saudi Arabia. It seemed quite large, nearly 2 inches.
Thanks for your time.

Jewel Beetle

Jewel Beetle

Dear Peter,
This is a Metallic Borer Beetle or Jewel Beetle in the family Buprestidae.  We located an image identified only by family on FlickR that looks very similar, and following up on that we found an image on FlickR identified as
Julodis speculifer dicksonae, also found in Saudi Arabia.  Continued research indicates there are many similar looking species in the genus based on this FlickRiver page, so while we are quite confident we have the correct family and genus Julodis, we cannot provide a definitive species identification.

Dear Daniel
Many thanks for your fast response.
I looked at a few of the beetles on Flickr that you linked to and I think it looks most like this one:
Julodis iris Laporte & Gory 1835
View on www.flickr.com
It’s called J. iris and it may be relevant that it was found among the wild iris fields there, flowering at just this time of year!
Best wishes
Peter

Found this metallic almost Rastafarian type beetle wandering around on the floor of my room. I tried to look it up but wasn’t able to find anything similar to this bug I found so I was hoping you may know.

Dear Paige,
Could you please be a bit more specific about the location.  Washington?  British Columbia???  This is a Golden Buprestid,
