South American Palm Weevil

Dear Classy Reader who writes with a Quill Pen,
This is a Weevil, a type of Beetle in the family Curculionidae, according to BugGuide:  “Arguably, the largest animal family with more than 50,000 species in ~4600 genera worldwide.”  Your individual is quite large for a Weevil, and we thought it would be easy to identify, however, the best we could do in a short amount of time is to find a matching image of an unidentified individual on the Highlights Along the Way blog.

South American Palm Weevil

We did additional research that included lightening a cropped version of one of your images that now reveals the details on the elytra, and we now believe this is a South American Palm Weevil, Rhynchophorus palmarum, a species that is also reported from Central America and is pictured on Insect Designs.  There is a UC Riverside pdf on this species that shows the horrific damage it can cause to palm trees.

Thank you for your reply. In the meantime I found out what species it is. Someone from iNaturalist who is also from Serbia said that there is actually only one species in Serbia which is Pentodon idiota.

Hi again Mihajlo,
Thanks so much for providing this update.

Your letter to the bugman:  This guy was sitting on a stucco wall, then moved to the pavement. Any idea what he/she is?  He/she was about an inch long.

Diaprepes Root Weevil

Dear Sarah,
Thanks for resending your images.  We are currently undergoing some technical difficulties.  This is a Diaprepes Root Weevil and according to BugGuide:  “Native to the Caribbean, adventive and established in so. US: so. & central FL (1964), so. TX (Cameron & Hidalgo Cos 2000, Corpus Christi 2005, Houston 2009;), so. CA (2005), LA (2008); further north in greenhouses.”  BugGuide also notes:  “highly polyphagous; larvae feed on roots, adults on foliage of citrus trees (esp. oranges in TX) and almost 300 other plant species” and “Major pest of citrus crops.”

Thanks so much, Daniel! I’d never seen anything looking like that before here in Southern California. (And I’m a native!) I guess I’ll kill any others I find since I do have citrus trees.

Your letter to the bugman:  We found this bug in the heliconia on our farm above Turrialba. It was early in the morning in June. The children would love to learn what it is and why it has hooks on its feet.

Weevil

Dear Holden,
This is a beetle known as a Weevil.  Based on Nature Closeups, it seems to be
Cholus costaricensis, and searching that name led us to iNaturalist.

Your letter to the bugman:  This thing landed on my arm in my office and i have no idea what it is. I didn’t feel any bite, all I felt was it land on my arm, and i brushed it off immediately. I just need it identified to know if I’m in danger of a parasite, infection, virus or otherwise transmittable illness. It has what I can only assume to be some form of proboscis and an empty white container on its “abdomen” with a grey/black and brown color and a somewhat fuzzy appearance. It also had a triangle-like shape when viewed top down.

Acorn Weevil

Dear Gerald,
This appears to be a very dead Acorn Weevil or Nut Weevil.  You need not fear “danger of a parasite, infection, virus or otherwise transmittable illness” from a harmless Acorn Weevil.

Your letter to the bugman:  I was standing on a dock by a lake for just a few minutes and after I got back in the car I felt something crawling in my hair. I found this green bug. He crawled but I never saw him fly so I am not sure if he could or not. I took this picture of it before letting it go back outside.

As you can see from this BugGuide image, you encountered a Green Immigrant Leaf Weevil,
Polydrusus formosus.  According to BugGuide:  “native to Europe (widespread there), adventive in NA, established in the northeast” and it feed on “primarily Yellow Birch.”

Your letter to the bugman:  Hi–
I saw this bug on July 23rd of this year and was impressed by its effective camouflage on the decaying bridge rail. It looks somewhat like a Southwestern Ironclad Beetle, but Tennessee is well out of that beetle’s range. Any idea what else it could be?

Avocado Weevil

Dear Curious in Tennessee,
We agree that your beetle resembles the Ironclad Beetle found from Texas westward, and we thought it resembled a Weevil, so we searched through Beetles of Eastern North America by Arthur V. Evans and we quickly located the Avocado Weevil,
Heilipus apiatus.  The book states:  “Adults are found year-round, but reach peak activity in summer, found on sassafras (Sassafras) and under pine (Pinus) bark.  Adults and larvae are serious pests of avocados (Persea); adults eat young fruits, while larvae bore and develop in base of trunk.  Virginia to Florida west to Tennessee.”  There are images on Forestry Images and on BugGuide.

Perfect! Many thanks for your quick reply. I’m going share your reply with my curious Facebook friends and encourage donations to WTB.
Best,
Maria
(aka Curious in Tennessee)
