Rosalia funebris - I hope to eventually find one of these.

Rosalia funebris - I hope to eventually find one of these.

I feel pretty lucky to have found it, just spotted on a log while out looking around. Then I saw several more on the same log so it must have been an emergence event.

I also found this lighting in the same area which was new to me too.



At the Fourth of July Campground near Tajique.

Hi MikeH,

Double-check your Enaphalodes atomarius - I believe this is actually Enaphalodes cortiphagus. And your Xylotrechus sp. from Cochise County is Neoclytus irroratus. Lots of good stuff!!

Cheers!

What is the best way to tell cortiphagus and atomarius apart? I had a hard time being certain on these.

Mike, what books do you use to ID your beetles?

Mike, what books do you use to ID your beetles?

My favorite approach is to post them on iNaturalist and let other people ID them for me but that does not seem to work that fast for longhorns, it is usually fast for Buprestidae and tiger beetles though.

I tend to use a few different sources for longhorns, "cerambycidae of North America" series is useful when I can get ahold of a copy but it is out of print and a little out of date. I can usually get a interlibrary loan at my local library from CSU or Univ of Wyoming but that does last long. A lot of times once I am confident about the genus, I will just Google or check bugguide for a key and that works sometimes, I've found that especially useful of Aneflomorpha for example.

I also have the two Evans books for eastern and western US which are nice to get close and a tiger beetles field guide which I don't find that useful, probably since I haven't spent enough time on it.

And volume 2 of American beetles which is super technical but should always key to a genus and have references to find a species key.

Great photos Mike, thanks for taking the time to post them.

Two places to know and to use:

-> Larry Bezarks Cerambycidae catalogue. A MUST for identifying longhorn beetles.

http://bezbycids.com/byciddb/wdefault.asp?w=n

-> Francesco Vitalis Cerambycidae-forum. A MUST for meeting colleagues, discussing and identifying specimens. A community of Cerambycidae enthousiasts both amateurs and scientists.

Hi Mike,

Sorry for the slow response - I'm rarely on here much due to a workload that's keeping me underwater.

There are differences in the shape of the last abdominal segments for both sexes, but the character I like to use is the nature of the elytral pubescence. In E. atomarius, the elytra are covered with short, erect golden setae in addition to the patches of grayish recumbent setae that create their mottled appearance. In E. cortiphagus, the elytra lack these erect setae, instead having dense recumbent gray setae only.

Hope this helps!

Hi Mike,

Your Phymatodes sp. from Baker County, Oregon is an interesting beast. I've never seen this species and the closest I can come to a name might be Phymatodes hardyi. There is just a single image on Bezark's site: http://bezbycids.com/byciddb/wdetails.asp?id=4571&w=n

The antennae on yours seem a bit different in the relative lengths of the antennomeres, but this could be due to your specimen and the one on Bezark being different sexes.

When I first saw this, I thought it could be a Haplidus species, but the locality is way out of range and it doesn't quite match that genus.

Very cool, whatever it is!!
