Patterson’s Curse Crown Weevil

Dear Jason,
This is a very unusual looking Weevil.  According to Australian Critters, it is a Crown Weevil,
Mogulones larvatus.  Prior to locating the image on that site, we found images on the Agriculture Victoria site where we learned that two species of weevils, the Crown Weevil and the Root Weevil, were introduced to Australia beginning in 1994 as biological control agents against and invasive plant known as Patterson’s Curse.  According to Agriculture Victoria:  “Paterson’s curse, Echium plantagineum, is a noxious weed of European origin that now occurs in most states of Australia and is mainly a problem in pastures, on roadsides and in degraded and disturbed areas. It reduces agricultural productivity by competing with more nutritious pasture plants and because it is toxic to livestock when ingested continuously. … The crown boring weevil and the root boring weevil are two European insects that have been released in Australia for the biological control of Paterson’s curse.” There are additional images on Atlas of Living Australia.

A little help if you please! My family enjoys looking up in wildlife guides, the bugs we find outside (and inside) our suburban home in Illinois. The closest thing we come up with for these two is the “spotted tiger beetle.” But these little guys are not spotted as the description/images/name would have us believe. Are they an undeveloped youngster version of this beetle perhaps? Or are we barking up the wrong bug? We’ve been able to identify all the other local insects thus far but are very unsure on this one. Thank you for taking the time to look! It’s kinda buggin’ me.

Green Immigrant Leaf Weevils

Dear Benjy,
Tiger Beetles are fast moving predators, and they are nowhere near as docile as these invasive Green Immigrant Leaf Weevils.  According to BugGuide:  “native to Europe (widespread there), adventive in NA, established in the northeast (NS-*SK to *PA-IL) + *UT & BC” and they feed on “primarily Yellow Birch (
Betula alleghaniensis).”

This little critter was sitting on my patio window this morning. Its about 75 degrees here today (4/2/17) and a lot of little things are finding their way out into the world. I live in middle TN and have all my 45 years but have never seen one of these. I’d say its about an 8th of an inch long and the picture is true to color.

Dear J,
This is some species of Weevil.  It might be the Butternut Curculio,
Conotrachelus juglandis, which is pictured on BugGuide.

Diaprepes Root Weevil

Dear Francis,
This is a Diaprepes Root Weevil,
Diaprepes abbreviatus, a species “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; map), so. CA (2005), LA (2008); further north in greenhouses” according to BugGuide, which also notes “color highly variable (from gray to yellow to orange to black).”  The Diaprepes Root Weevil is a significant agricultural pest, and according to BugGuide:  “Major pest of citrus crops: larvae often girdle the taproot, which may kill the plant and provide an avenue for Phythophora infections. A single larva can kill young hosts while several larvae can cause serious decline of older, established hosts.”  According to Featured Creatures:  “Diaprepes abbreviatus has a wide host range, attacking about 270 different plants including citrus, sugarcane, vegetables, potatoes, strawberries, woody field-grown ornamentals, sweet potatoes, papaya, guava, mahogany, containerized ornamentals, and non-cultivated wild plants.”  Since it is the first of the month, we will be featuring your submission as the Bug of the Month for March, 2017.

I greatly appreciate your response and am honored that this photo will be the feature of the month! We’ll be sending more photos to share from Learning Gate Community School.

Here’s a photo of a large (>1″) weevil. Any ideas as to species?

Dear R Lockett,
Like you, we have not had much luck finding out a species name, and the closest visual match we found in our brief web search was this FlickR image of a much darker colored, unidentified Weevil from Madagascar, however, the markings on the legs do look quite similar, which causes us to speculate that perhaps this is a species that shows much variability in its markings.

Update from Cesar Crash who identified Rhytidophloeus rothschildi
Cesar provided us with a link to FlickR that identifies Rhytidophloeus rothschildi.

Dear Bugman,
I find this bug in copious numbers on the floor and along the baseboards in my home. They are in multiple, nonapproximateing rooms and are almost always dead. Please identify them for me and tell me what, if any, action I can take to rid my house of this population. Excuse the lack of magnification, this is as close as I can come with my iPad.

Grain Weevils

Dear Frederic,
These are Grain Weevils, and you need to locate the source of the infestation.  Start with rice in the pantry or that big bag of bird seed you have stored somewhere.  They will also infest bargain bags of pet food.

Mr. Marlos,
Thanks for your prompt reply! I will get right on the case and see if we have any of those items you mentioned lying around loose.  I will also lace the areas with a residual insecticide. Thanks again for your prompt service.
