We were splitting Madrone firewood today (10/19/14), and it was full of borers of some kind. There were two varieties. The black & green variety was the most common (probably 90%), but there were also some of the red and black. We’re interested in learning more about them, particularly whether they’re a threat to our woods.

Hi Jim,
We have not had much luck identifying your red and black beetles, but it might be partly due to the lack of clarity in the images, and that they look velvety in texture, but we are not sure if that is an illusion.  Please clarify the tomentosity of your beetle, because other than the apparent texture of your individuals,  they remind us of Pleasing Fungus Beetles which are pictured on BugGuide.  Perhaps one of our readers will be able to write in with an identification.

Daniel,
Just saw this post on your page. It is a clerid beetle, Chariessa elegans <http://bugguide.net/node/view/169445>.
Cheers, ART

Subject: Inornate Checkered Beetle Eating Grasshopper Eggs?
Location: Albuquerque, NM

Lately I’ve run across several strange beetles in the house of a type that I don’t remember having seen before. I looked around on Bugguide.net for a while and think I’ve managed to identify them as Inornate Checkered Beetles. There doesn’t seem to be much information on this particular species, but a quick internet search indicates that some checkered beetle species feed on grasshoppers and grasshopper eggs, and we’ve been having a local explosion of grasshoppers lately. (Third picture is an example of one of these grasshoppers.) What do you think?

Hi Cat,
We have researched the Inornate Checkered Beetle,
Cymatodera inornata, which we have located on BugGuide., and we believe you have correctly identified the genus, but the species may be incorrect because the distribution map for the Inornate Checkered Beetle does not contain any sightings west of the Mississippi River.  The description of the species on BugGuide indicates its range as being:  “Eastern N. Amer. to UT & AZ,” supporting your identification of the species.  Another member of the genus, Cymatodera dietrichi,  looks very similar and is found in New Mexico and Texas, according to BugGuide.  Of the genus, BugGuide notes:  “adults are predaceous, feeding (in part) on the larvae of gall wasps, fruit tree lepidoptera, and wood-boring beetles” and there is no mention of Grasshoppers.

Your identification of the Pallid Winged Grasshopper, Trimerotropis pallidipennis, appears to be correct based on images on BugGuide.  We don’t believe there is any relationship between the appearance of the Checkered Beetles and the large number of Grasshoppers, but we might be wrong.

Thanks! We still get plenty of wood-boring beetles and fruit tree lepidoptera around here too, so the checkered beetles will still be able to find plenty to eat even without the grasshoppers!

Hi there,
We import a dry dog food from Midwest US and with the last few containers we had a blue bug in the container. The container is transported via the Panama Canal from Pennsylvania – we wonder if it could have some from there.
I am sorry but my photos are not that good.. but here we go..
Image 1: dead, but you can see the legs
Image 2: dead, but you can get an idea of the size
Image 3: there are about 5-6 live ones in the bag with the dog food
Your help will be much appreciated

Red Legged Ham Beetles in Dog Food!!!

Red Legged Ham Beetles in Dog Food!!!

Dear Malene,
Thank you for your patience.  It appears you have an infestation of Red Legged Ham Beetles,
Necrobius rufipes.  Even though the photo is blurry, the red legs are very obvious in your second image.  According to Forensics Topics, a high profile occupation thanks to all the crime scene investigation shows on television:  “This beetle is small in size with a bluish/green metallic body. Notice the red leggs-hence [sic] the name. This beetle shows up during dryer stages of decomposition.”  We suspect that there are also larvae in the dog food.  According to BugGuide:  “found on dried fish, skins and bones of dead animals, and other carrion; also found on museum specimens” and “Eggs are laid on the food material; larvae pass through three or four instars; the last instar spins a cocoon in which pupation occurs; life-cycle takes 6 weeks or longer depending on food type and physical conditions. Under optimum conditions, the rate of population increase is about 25 times per month. The adults fly actively and can thus easily disperse to new sources of food.”

Thank you so much Daniel. Much appreciated.

Dear Mr. Bugman, I am glad to be able to return to this site again.
This time I have found a tiny ant-like beetle which I could not identify.
It’s length is smaller than 15mm. Could it be a Cleridae species?

Dear C. X. Wong,
Your beetle does resemble a Checkered Beetle in the family Cleridae, but we cannot say for certain that is a correct family identification.  Perhaps one of our readers will be able to confirm the family and provide some more specific information.

First thing that came to mind was lady bug, but it’s not similar in shape. Found in Cincinnati in mid-spring.
I live in Cincinnati, OH, and never saw so many different types of insects before, I moved here from cold Minneapolis, MN.

Dear Emily Rose,
We quickly dismissed that this might be a Leaf Beetle and we then identified it as a Four Spotted Checkered Beetle,
Pelonides quadripunctatus, thanks to images posted to BugGuide, which indicates the beetles are active:  “March-May.”

Dear WTB,
I took this picture in my kitchen before putting it in the garden- it looks like it could nip. It was probably staying out of the sun. I cant say I’ve seen one here ever -France. It is about 1-1.5 cm in length. It looks like venom from spiderman , maybe the inspiration. Thanks

Dear Alan,
This is a Checkered Beetle in the family Cleridae, not a spider.  According to BugGuide, Checkered Beetles are:  “predaceous on other insects, larvae mostly on wood- and cone-borers; some adults feed on pollen; a few species are scavengers.”  Your Checkered Beetle looks somewhat similar to this image of
Thanasimus formicarius from FlickR.
