Your letter to the bugman:  I found this little guy scurrying on the basement floor of our house. For a moment I thought it was a caterpillar and was going to stomp on it, but I realized he was not going to become a moth and took some pics. I’m pretty sure this is some sort of beetle but I’ve never seen one like this before! And FYI once I took these pics I let him go outside. I am of the same mind with respect to most bugs 🙂

Longicorn:  Neoclytus mucronatus

Dear Amanda,
This is a Longicorn or Longhorned Borer Beetle in the genus
Neoclytus, and it has no common name.  We believe we have correctly identified it as Neoclytus mucronatus thanks to this image on BugGuide.  It is one of the species that mimics a stinging wasp like a Paper Wasp for protection as the beetle does not sting, but potential predators are put off by the warning colors.

Longicorn: Neoclytus mucronatus

Thanks for the swift response! I’m glad you were able to ID this for me. The markings on the wing casings kept me from seeing that it was any kind of beetle. I guess mimicry works to fool amateur entomologists too.

Flat Faced Longhorn is Neoptychodes trilineatus

Hi Gabe,
Your images are quite artful.  This is a Round Headed Apple Borer, a native to North America.  According to the Michigan State University Integrated Pest Management System:  “Attack apples mainly, but most deciduous tree fruits are susceptible. The larvae dig tunnels, most often at the base of the tree trunk. The roundheaded borer leaves accumulations of reddish frass at the entrance of galleries. Infested trees have a sickly appearance, producing sparse, pale-colored foliage (C). Continued yearly attacks can kill the tree or weaken it so that it is broken off by the wind. Young trees that have been girdled will often bloom profusely and set a heavy crop of fruit and then die in the process of bringing it to maturity.”

Neoptychodes trilineatus

Correction: Neoptychodes trilineatus
We just received a comment from Brady Richards correcting this misidentification.  According to BugGuide:  “Although Ficus is the primary host, larvae also develop in Alnus, Morus, Salix, Celtis. ”

Sugar Maple Borer

Dear Melissa,
This gorgeous beetle is a Sugar Maple Borer, and it is a very effective mimic of Yellowjackets.  Sugar Maple Borers have become increasingly rare in recent years, so your sighting is significant.

Lion Beetle

Dear JbTv,
Thanks so much for submitting your excellent images of a Lion Beetle, even though you did not require an identification.  We are happy to learn our site was helpful to you.  What we especially like about your Lion Beetle images is that the individual has curled up its abdomen into what is commonly regarded as a threat position that would be assumed by a stinging insect, and which we frequently see in Rove Beetles like the Devil’s Coach Horse.  This posture is especially effective in insects that mimic stinging insects, like your Lion Beetle.

Diaprepes Root Weevil

Dear Mike,
This is an invasive Diaprepes Root Weevil,
Diaprepes abbreviatus, and according to the Statewide Integrated Pest Management Program:  “The diaprepes root weevil damages both the leaves and the roots of plants. The adult weevils damage leaves by chewing semi-circular areas out of the leaf margin. There may also be frass or weevil droppings near the areas that have been fed upon. The grub-like larva feeds on the roots of a plant, weakening or killing a plant.”  According to the Center for Invasive Species Research:  “This pest has a very wide host range, attacking more than 270 species of plants in 59 plant families.  In Florida citrus groves, Diaprepes root damage allows, Phytophthora, a very serious and often lethal plant pathogen to invade roots further hastening the decline of trees.”
