Male Root Borer

Dear Bug Master,
This is a Root Borer in the genus
Prionus, and we strongly suspect it is a California Root Borer, Prionus californicus, which is pictured on BugGuide.  Despite its name, the California Root Borer’s range includes much of western North America.  We would not rule out that it might be Prionus heroicus, which is also reported from Utah on BugGuide.  Either way, those impressive antennae indicate this is a male Root Borer.  Root Borers have powerful mandibles, so they should be handled with caution, but they are not considered dangerous.  Many species are attracted to lights.

Your letter to the bugman:  My wife photographed this beetle while we were camped at Frost Mountain, WA, 7/29/19. It’s back appears to be a leaf, but it looks like it’s actually a part of it’s body. What is it and is the “leaf” a real leaf that the beetle attached to itself or is it something the beetle was born with?

Flower Longhorn: Pachyta armata

Dear Kevin,
This is a beautiful Beetle, and it is all Beetle with no leaf.  We started by searching for Flower Longhorns in the subfamily Lepturinae, but without much luck.  Then we found a thumbnail on Hiveminer that led us to this FlickR posting of
Pachyta armataBugGuide has many images, but not much information.  iNaturalist also has images, and not much information, but sightings apparently peak in July/August.

Lion Beetle

Dear Richard,
Though this looks very much like a Bee, it is not.  One can’t even begin to contemplate the complexity of the transformational events that caused this Lion Beetle,
Ulochaetes leoninus, to mimic the appearance and behavior of a stinging insect for protection from predators and other threats that have learned to avoid aposomatic or warning colors and markings after having first been stung.  The first time we received an identification request for a Lion Beetle, we were quite confused ourselves.

Lion Beetle

Hello Daniel,
thanks so much for the identification.  We did our best with images but no luck.  We were beekeepers for a few years and were puzzled by this critter. The loin like tuft of fuzz like a bumblebee on a body most resembling a queen honey bee was a strange sight.  I’m grateful to have had a chance to see one fly and land close enough to take a couple of photos.
Cheers,
RIchard

Subject:  What type of fly is this?
Geographic location of the bug:  Brantford, Ontario

Your letter to the bugman:  Hello Bugman,
I am hoping that you can help me identify this fly. I was leaning toward a type of syrphid fly but could not find a match online. Any help would be greatly appreciated.
Thanks!

Signal Fly (left) and Red Milkweed Beetle

Dear Dan,
The image of the Fly with the Red Milkweed Beetle is an easier image for identifying purposes as it clearly shows the wing pattern on this Signal Fly in the genus
Rivellia which we determined thanks to images posted to BugGuide where it states the habitat is “on foliage, feces.”  We tried to determine if there is a relationship between Signal Flies and milkweed, and we located this BugGuide image and this BugGuide image and on The Pathless Wood we found an image and this information:  ” I did come across this interesting fly in my search, however, and later determined it is some sort of Signal Fly, a member of the Genus Rivellia. These flies are often difficult to identify from photographs alone; they are quite small, and identification depends on the presence or absence of tiny hairs called setae on the dorsal thorax, as well as the colour pattern of the wings and legs. They get their name from their patterned wings, which they tend to wave around as if signalling other individuals. I didn’t see this behaviour as this individual rested on an unopened milkweed blossom, so I was immediately taken with the unique pattern of its otherwise clear wings.”   So, for some reason, Signal Flies are attracted to milkweed, but we are not certain why.  Are there soybean fields nearby?  Your individual reminds us quite a bit of the Soybean Nodule Fly, Rivellia quadrifasciata, which is also pictured on BugGuide.

Mating Signal Flies

Hi Daniel,
Thank you for this information. There was a soybean field right next to this patch of milkweed so I think it may be safe to say Rivellia quadrifasciata is a match. I’ve seen other flies exhibit this behaviour of waving their wings around. Now I know where to start when trying to identify them.
Thanks again!
Dan
