Your letter to the bugman:  Maam/Sir, good day!
I am Maria Tanola, a Biology student of University of Southeastern Philippines. As part of our curriculum, I was provided with an unidentified weevil species for me to work with. I have been working on this case study for months now, however, I came up with Otiorhynchus singularis (italicized) and Otiorhynchus sulcatus (italicized) as an initial identification. I believe that this unidentified species is just between the two. Hence, I am writing to humbly request your service and expertise to confirm or correct my initial identification for the abovementioned weevil species.
I am looking forward for your urgent response as this is a timely matter.
Sincerely,
Maria

Dear Maria,
Your photomicroscopy images of a Weevil are quite detailed, but alas, we do not have the necessary skills to answer your very detailed question.  Perhaps one of our readers will be able to assist you by submitting comments.

Your letter to the bugman:  Hi,
I have been trying to identify this Beetle on your site and the closest I can come is that it is a darkling beetle. This one was alive, two others that I found in my apartment this week were already dead. Beatles are not poisonous are they? Thanks for your help!

Weevil

Dear V,
We believe this is a Weevil, and based on the image posted to the Northeastern Integrated Pest Management Program site, it resembles the Annual Bluegrass Weevil,
Listronotus maculicollis, and when we researched the species on BugGuide, we found that it is a relatively large genus represented on BugGuide and the tribe to which it belongs has two genera, and many members look similar, so we feel confident this is a Weevil, and it might be a member of the tribe Listroderini, but we are uncertain of the species.

Hi Daniel,
Thanks so much for your quick identification! I now know how to research what to do about them. Have a great night.
Best,
Venessa

Your letter to the bugman:  Been trying to identify this bug I’ve found, but can’t seem to find the right species. I came across this beauty while hiking in the Monteverde Cloud Forest. Could you help me out?

Palmetto Weevil

Dear Nick,
This sure looks to us like the highly variable Palmetto Weevil or Red Palm Weevil,
Rhynchophorus cruentatus, based on this image posted to BugGuide.  According to Revolvy:  “The adult beetles are relatively large, ranging between two and four centimeters long, and are usually a rusty red colour—but many colour variants exist and have often been classified as different species” and “Weevil larvae can excavate holes in the trunk of a palm trees up to a metre long, thereby weakening and eventually killing the host plant. As a result, the weevil is considered a major pest in palm plantations, including the coconut palm, date palm and oil palm.”

Daniel,
Thank you so much for identifying the bug! Also, Palmetto Weevil is a more than lovely name.
I’ll add this to my list of animals I’ve found on my trip.
Thanks again,
Nick

Weevils

Dear Debbra,
We believe you should look elsewhere for your biters.  These are Grain Weevils.  They are a common household pest that will infest stored food products including rice, bird seed and pet food.  We do not believe they are biting you.

Diaprepes Root Weevil

Dear Frank,
This is an introduced Diaprepes Root Weevil,
Diaprepes abbreviatus, and according to BugGuide it is:  “color highly variable (from gray to yellow to orange to black)” and “highly polyphagous; larvae feed on roots, adults on foliage of citrus trees (esp. oranges in TX) and almost 300 other plant species.”
