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.

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.

Green Immigrant Leaf Weevil

Dear Jayne,
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.

Mating Weevils

Like you, we have not had any luck determining a species identity for these mating Weevils.  We did locate an image at the very bottom of the Homestead Brooklyn blog page devoted to Tapanti National Park that is unidentified and another similar looking individual from Selva Verde, Costa Rica that is unidentified on Alamy.  The Costa Rica Research page of the Microbiology at Occidental College site also has a similar looking unidentified Weevil on it.  Finally, we located your image on Jungle Dragon.  Perhaps one of our readers will have better luck than we have had.

Mating Weevils

Thank you for your help!
It is always very tricky to identify CR insects.  There are no books and no good web sites, only those meant for biological warfare identify ‘plagas’ or pests..
With best wishes

Mating Figwort Weevils

Dear Rick,
These are mating Figwort Weevils,
Cionus scrophulariae, which we identified on Bug Blog and the verified its identity on UK Beetle Recording.  According to Nature Spot:  “Fairly frequent and widespread in Britain with fewer records from the north” and the habitat is “Around the foodplants Figwort and Mullein.”
