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.”

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.

Your letter to the bugman:  This was hanging out inside my trunk. I used a twig to detach it, but it was holding on with super strength.

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.”

Your letter to the bugman:  Hi, I would like to identify these beetles, they were very big sizes about 10+ centimeters. People here are afraid of them and call them “big cockroach”.
Nearby there are eucalyptus trees and lots of sugar cane.
I would like to know if they are rare, because these photos are from November 2018 and since then I have not seen any more here (the first beetle is slightly smaller than the second).
The first question is: are they dangerous?
What is his life time? what does he feed on? and how is his larval state?

Root Borer

Dear Kainã,
This is one of the Root Borers in the subfamily Prioninae, and it looks similar to
Ctenoscelis ater which is pictured on Coleoptera Neotropical, but there is no information on the site regarding this beetle’s life cycle.  There is an image but no information on Prioninae of the World.  There is one sighting on iNaturalist.

Ocellated Tiger Beetle

This harmless, predatory Tiger Beetle did not kill your tree.  We believe we have correctly identified it as an Ocellated Tiger Beetle thanks to this Gossamer Tapestry image and this BugGuide image.  We will be tagging this submission as Unnecessary Carnage in an effort to educate the public that every insect encountered is not a threat.

Cara on Facebook Asks:  Why do people kill first, then ask questions?!
