Your letter to the bugman:  This cute little fellow got us all wondering what species he might be. He was spotted on the bank of the Willamette river near the forest’s edge in April. Any idea? Thanks so much for any insight you might have!

Inflated Beetle

Dear Beetle Bystander,
This is a Desert Spider Beetle or Inflated Beetle in the genus
Cysteodemus.  According to BugGuide, there are two species in North America and neither is reported from Oregon, and the range is listed as “sw. US: Colorado, Mojave, and Chihuahuan deserts.”  We are not certain how unusual this Oregon sighting is.

Iron Cross Blister Beetle

Dear Puzzled in Phx,
The first time we ever received an image of gaudily colored Iron Cross Blister Beetle, we thought we were looking at a toy bug.  They would seem to be right on time based on our posting five identification requests of Iron Cross Blister Beetles at the beginning of May 2010.  Populations of individuals will vary from year to year.

Blister Beetle: Tricrania sanguinipennis

Dear Abigail,
Generally, when we receive an identification request, we have at least an idea to what family a creature belongs, which makes research easier, but in the case of this Beetle, we were not even sure of a family.  We turned to Arthur V. Evans excellent book Beetles of Eastern North America and we eventually identified your colorful beetle as a Blister Beetle in the family Meloidae,
Tricrania sanguinipennis, but it is very atypical looking for a Blister Beetle.  We located an image on BugGuide for comparison.  According to BugGuide, it is “A parasitoid of colonial bees, such as Colletes.” 

Thank you so much for replying! I’m glad to have provided a challenge. After contacting you, I remembered about our local agricultural station. They were also able to ID my beetle as the Tricrania. I’m guessing they are thoroughly enjoying my ground bees….

Master Blister Beetle

Dear Clint,
Thanks for writing back to us to inquire on the status of your identification request.  We went back through unanswered mail and located your stunning images of a Master Blister Beetle.  We posted our first images last week of the magnificent Master Blister Beetle, though in fact your images were submitted more than two weeks earlier.  Please excuse our lag time in responding.

Master Blister Beetle

Not a problem. This is the first time I have ever seen one of these in my 40 years plus living in 29 Palms. Thanks for replying. You can do what you want with the images.

Is it foreign? Or diseased? Thank you for helping me identify this beetle, I am so curious to find what it is!

Oil Beetle

Dear Knitwit in the poconos,
This is a Blister Beetle in the genus
Meloe, commonly called an Oil Beetle.  Blister Beetles should be handled with caution as some species are capable of secreting a compound known as cantharadin that can cause blistering in sensitive individuals.

Wow! Thank you for the quick reply and the great info!
