Hello there,
We live on a wooded property in southeastern Quebec . We found this beautiful creature on the steps behind our house. He/she was dead, a bit flattened, so we presume one of us had inadvertently squished the poor thing.
Could you help us identify it ? Coleopteran of some sort, as far as I can determine. Thank you so much for your help.

Sugar Maple Borer

Dear Anke,
Your beautiful beetle is a Sugar Maple Borer,
Glycobius speciosus, and according to BugGuide, they are considered “rare” and because of the bold markings “Appears to be a mimic of Yellowjackets.”

Thank you so much for the id. A very special discovery for us in the 30 years that my parents have lived on this property.
Regards,
Anke

Dear Sarah,
This sure looks like a Whitespotted Sawyer,
Monochamus scutellatus, to us.  According to BugGuide:  “Two-year life cycle. Larvae excavates galleries in coniferous trees, often after they are damaged by a fire, storm, etc. Common hosts are: Balsam fir, spruces and white pine.”

I found this insect while picking blackberries. I have no idea what it is but was fascinated by the size and nobbles of its antennae. I would love to know more about it. I hope the photos are useful. With kind regards

Musk Beetle

Musk Beetle

Dear P. Carr,
This Longicorn in the family Cerambycidae looked familiar to us, but we were uncertain of its identity, so we decided to search our own archives.  Our first matching image is this Unidentified Longicorn from Serbia which we believe is the same species.  We then found another similar looking individual from Sweden that we identified as a Musk Beetle,
Aromia moschata, though it is green as opposed to purple.  The Eakring Birds site pictures both green and purple individuals, leading us to deduce that we have a correct identification on your beetle.

Flat-Faced Longicorn

Flat-Faced Longicorn

This is a Longhorned Borer Beetle or Longicorn in the family Cerambycidae, and it is a Flat-Faced Longhorn in the subfamily Lamiinae.  Though we are not certain of the species, we believe it is a Spotted Tree Borer, Synaphaeta guexi, an impressive species and every year we get one or two identification requests from California.  We wish you had submitted a dorsal view as it is easier for us to identify a beetle with a dorsal view.  Compare your individual to this image from BugGuide, also from Lassen.

thank you for the quick response and the coaching on best angle for a picture.

We should also add that your images are quite stunning, and we did not mean to imply that they are substandard.  We are certain that any coleopterists out there would have no trouble providing a species identification based on your images, but we have no such credentials, so for our staff, dorsal views of insects are the best for identification purposes.

Dear Bugman,
Attached is a picture of a bug taken ending of July 2015. I saw at least 4 of them coming around my apartment. Can you IF the bug so that I can learn more about them?
Thanks,

Mango Stem Borer

Mango Stem Borer

Dear Andres,
We were not aware that the Mango Stem Borer,
Batocera rufomaculata, an Asian Longhorned Borer Beetle that has been accidentally introduced to the Israel where it is threatening mango, fig and avocado trees, had been introduced to the New World, however, Discover Life indicates:  “B. rufomaculata is a polyphagous species which attacks both living and dead trees. While it tends to attack living trees which are stressed, it will also sometimes attack apparently healthy trees. The host range differs throughout the species’ range, but mango and fig are the two most commonly attacked hosts.  Wild Ficus spp. were attacked and killed in the Caribbean.”  No date is provided for when the Mango Stem Borer was first introduced to the Caribbean.  Since this is a non-native introduction, we are tagging your submission as one of the Invasive Exotics.
