Your letter to the bugman:  Hi, maybe you can help? I’m just curious to see if this is a moth, beetle, or cockroach. Hopefully not a cockroach.

Dear J,
This is neither a moth nor a Cockroach, but it is a Beetle.  It is a Firefly.

Subject:  What type of fly is this?

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.

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!

Sexton Beetle

Dear Natalie,
This is a Sexton Beetle in the genus
Nicrophorus.  Your individual has very few red spots, so it was easy to identify as Nicrophorus pustulatus on BugGuide.  According to BugGuide: “Reported to be a brood parasite of other Nicrophorus. Also reported to parasitize the eggs of Black Rat Snakes, Elaphe obsoleta (Blouin-Demers & Weatherhead 2000, Trumbo 2009). The beetle larvae destroy the snake eggs, thus, the beetle would qualify as a parasitoid of the snake, a relationship usually seen only among invertebrates. In the wild, N. pustulatus is not known to exhibit the usual carcass-burying behavior of other members of its genus, though it will display some of this behavior in captivity. There is suspicion, too, that it may parasitize eggs of other reptiles, and, perhaps, birds (Trumbo 2009).”

Golden Buprestid

Dear Tyson,
Your beautiful beetle is one of the Metallic Borer Beetles in the family Buprestidae.  It is a Golden Buprestid,
Buprestis aurulenta, and here is a BugGuide image for corroboration.  We have a letter in our archives regarding a Golden Buprestid that emerged from an eight year old cutting board.

Red Headed Ash Borer

Dear Brandon,
The Red Headed Ash Borer,
Neoclytus acuminatus, is a beetle that benefits from protective mimicry because it looks and acts like a stinging wasp.

Your letter to the bugman:  I’m trying to identify the following bug. It is about 1/8″ – 3/16″ long, black with hints of yellow, long antenna, and hair. I believe that it latched onto me while I was hiking through an area near a pepper tree and pine tree. I’ve searched the Internet without luck, but not the Dark Web 😉 Thanks!

Longhorned Borer Beetle: Ipochus fasciatus

Dear RedSect Bug Lover,
We hope you are not considering us the Dark Web.  This is a Longhorned Borer Beetle in the family Cerambycidae, and we actually thought we were going to have a much more difficult time identifying it than we had.  We quickly identified it as
Ipochus fasciatus on BugGuide. According to Oxford Academic Group:  “Ipochus fasciatus LeConte apparently has newly, but imperfectly, adapted to feed and oviposit in milk thistle, Silybum marianum (L.) Gaertner, an alien, herbaceous, annual weed in southern California. This polyphagous, native cerambycid previously was known only from woody, perennial host plants.”  Knowing it has adapted to feeding on the invasive Milk Thistle is a good thing.

I was making a joking reference to the Dark Web, since I had such a difficult time finding info on the Ipochus fasciatus on the InterWeb.
I also had a difficult time finding any details on this little guy, but found this passage below about what it likes. We have the Rhus laurina (Laurel Sumac) on our hillside and this must be what attracted it.
Thanks for the ID and Info!

Hi again RedSect,
Several of the plants in the list on your attached screenshot are growing in the WTB? gardens, including Laurel Leaf Sumac, Oak, Willow and endangered California Black Walnut.  We will keep an eye out for this diminutive Longhorned Borer Beetle.
