Your letter to the bugman:  Hi! Today I was sitting out on my deck when I heard this beetle  land. It looks to me like a species of Longhorn, I was concerned it might be an invasive. Can you help identify it? Also, got to enjoy watching a Four-toothed Mason wasp search for the right spot under the railing too while out.

Red Headed Ash Borer

Dear Keith,
This is a Red Headed Ash Borer,
Neoclytus acuminatus, or a closely related species of Longhorned Borer Beetle.  All indications are that the color, markings and behavior of the Red Headed Ash Borer mimic that of a stinging wasp, which protects the harmless beetle from potential predators.  According to BugGuide:  “Larvae feed on the sapwood of ash and other hardwoods, and even occasionally on vines and shrubs. Larvae are common in downed timber with the bark left on.”

California Prionus

Dear Davies,
June and July are the months we receive most North American Prionid sightings, a subfamily of especially large Long-Horned Borer Beetles.  This is a California Prionus or California Root Borer,
Prionus californicus, and according to BugGuide:  “Larva feed primarily on living deciduous trees (oaks, madrone, cottonwood) and are also recorded from roots of vines, grasses, and decomposing hardwoods and conifers. Will also attack fruit trees growing on light, well-drained soils (e.g. apple, cherry, peach).”

Longhorned Borer Beetle

Dear Rich,
The Sugar Maple Borer is a much larger and even more colorful Beetle.  Your individual is also a member of the Longhorned Borer Beetle family Cerambycidae, and we believe we have identified it as 
Clytus ruricola, a species with no common name, thanks to images on BugGuide.  According to BugGuide:  “Larvae in decaying hardwoods, esp. maple (Acer)” so it is theoretically a “Maple Borer.” 

Thanks. I did more research and it’s equivalent to the clytus ruricola. Very unusual but it’s native to northeast US. Thanks for the identification help. Feel free to use the image on your site for future identification. I’m going n Putnam County, NY.

Subject:  Wasp, hornet, or bee?

Your letter to the bugman:  I noticed 2 or more dozen of these in a firewood pile I have on the side of my yard. I need to stack it to season for next winter. I don’t necessarily want to disturb bees if that’s what they are but I also don’t want to get stung by a swarm and find out if I’m allergic if they are Hornets or wasps.

Banded Ash Borer

Dear Ross,
This isn’t a “wasp, hornet, or bee” but rather a Longhorned Borer Beetle in the genus
Neoclytus, probably the Banded Ash Borer, a native species that we identified on BugGuide.  According to BugGuide:  “Adults emerge May-Aug in the North, Feb-Nov in the South” and “often emerges indoors from firewood; sawlogs may become infested within 20 days of felling during summer.”  You will not be stung if you stack the wood.

Your letter to the bugman:  What kind of bug is this and will it bite? Does it fly?

Spotted Tree Borer

Hi Kayla,
This is a Longhorned Borer Beetle in the family Cerambycidae, and we are very confident that it is a Spotted Tree Borer,
Synaphaeta guexi, based on images posted to the Natural History of Orange County site.  It does fly and it has very strong mandibles it uses to chew its way to the surface after it matures from a wood boring larva to a winged adult.
