Can you help me identify this bug? They show up every now and then.
Thank you

Larder Beetle

Hi Brian,
You are being troubled by Larder Beetles, a cosmopolitan species that infests stored foods.  Check the pantry for old food items and the source of the infestation.  See BugGuide for more information.

Grain Weevil

Dear Donks,
This appears to be a grain weevil.  Look in the pantry for infested grain products like rice.

Thankyou,  they were coming from a bag of bird seed that was being stored until summer.

Small bug found on guest bed!
Location: Central FL
January 15, 2012 10:53 pm
I found this bug while changing the bedsheets on our guest bed. It hasn’t been used for almost a year and I have been doing some cleaning in there. I went in today to lay down some clean sheets and found this little guy on the foam topper that lays on the mattress. I really hope it’s not a bedbug! I searched the creases of the mattress and between the mattress and box spring but couldn’t find anything else. I have guests coming in four days. Should I be worried?

Carpet Beetle

Dear Elizabeth,
In our opinion, this appears to be one of the Carpet Beetles in the family Dermestidae, a group that includes many household pests.  Many of the Carpet Beetles look very similar, and yours is a close match to a
Megatoma variegata which we found on BugGuide, though it is only represented on BugGuide from the western states.  We are not terribly concerned with the range report on BugGuide as Carpet Beetles tend to be cosmopolitan in their distributions.  Carpet Beetles feed on a wide variety of organic fibers and substances including wool rugs an upholstery, taxidermy specimens, fur coats, museum specimens, pet hair and even stored foods.  They will not bite your house guests.

Thanks for getting back in a timely manner! Glad to hear it isn’t anything serious. Thanks again!

Mealworm confusion, looking for expert
December 18, 2011 7:44 pm
I know you’re terrifically busy in all senses of the word ‘terrific’, but I was hoping you might ask your entomologist backup crew to get in touch.
I’m starting out with mealworms and have some rather odd things going on in the colonies.  Major size differences in larval stage just before pupation and in pupae is only the beginning…!
I’m suspecting a mix of species, but which species?  Need to know so I can give them each their optimum environments, and I’m totally lost. :)
Have pics, can send, can take more…
And any help, as always, is wonderfully appreciated!

Mealworm Pupae

Mealworm pupae size difference

You ROCK, folks…!
This is a picture of a darkling beetle, matured from one of my mealworm colony pupae–and in the next pictures, you can see there is a huge size difference between two distinct groups. Supplier A’s mealworms are larger at pupation and make large pupae; Supplier B’s mealworms are pupating at a smaller size and result in smaller pupae.
I suspect a mix of species–let me know what photos will be most helpful in ID’ing the darn things?
Thanks so very much for all you do–I swear, I recommend you to about six teachers a year. *evil grin*

Mealworm Pupae

Ed. Note:  These two emails came minutes apart, and despite the different signatures and email addresses, we suspect they have the same origin.

Darkline Beetle: Mealworm

Dear Pamela and/or Onafixedincome,
Since your two emails came minutes apart, and deal with a similar subject matter, we suspect they are related despite different signatures and different email addresses.  Please confirm our suspicions.  Additionally, since only onafixedincome sent photos, we are treating this as a single posting and we will respond to both together.  Mealworms are a common commercial name for the larvae of Darkling Beetles that are raised as food for a variety of pets including larger tropical fish, turtles, lizards and frogs.  The Aquatic Community website has a nice page on Raising Mealworms.  The common commercial species is the Yellow Mealworm,
Tenebrio molitor, though we suspect other species may also be raised commercially, which might be one explanation for the size discrepancy you have witnessed.  Individual species also have considerable variation in size from individual to individual, and this may be partially explained by genetic traits.  Perhaps one supplier has individuals that are passing on a gene that is producing smaller larvae and pupae, and this is producing smaller adults.  We hope someone with experience will provide a comment to this posting, though sometimes comments take years to be posted.  We would recommend that you place a comment to this posting so that you will be notified in the future if there are any comments or answers to your questions.

Whups!  My apologies, wasn’t trying to be sneaky…Just brainless as usual, which takes little effort. :(
I wasn’t going to send you pics, because they are ‘domestic’ insects, then thought you might find them fun, if not useful, so posted them.  The difference in emails was a screwup, and I am sorry.
Any rate, I appreciate your input as always!–can’t imagine how you manage to keep up with all this stuff.
Given the current average of malformation (50%+) thus far on the large pupae, I’m leaning toward the theory that these were treated with with growth hormone to get size–and that the beetles from these may well turn out sterile. :(
So, I guess I’ll just have to wait and see….Much obliged for the link, it’s always good to learn as much as you can when raising anything, even bugs! :)
Again, you ROCK!!!
And of course, thank you so very much. :)

Bug I have never seen before

I first found this bug last night when I got some bedding out of my daughter’s closet. Only saw one, but then I saw two more this afternoon in a laundry basket in the basement. Any idea what this is?

Bed Bug, Carpet Beetle Larva or other???

Hi Megan,
There is not enough detail in your photo for us to say with any certainty what the identity of your insect might be, but two possibilities are a Bed Bug or a Carpet Beetle Larva.  A better photograph would help.

I know for a fact that it isn’t a bed bug.  Have too much experience with those so I know exactly what those look like!  I looked up carpet beetle larva and found this picture (attached).  It looks like the bug on the left.  Now to research these things and find out more about them.  Thank you!

No Clue

Hello Mr. Bugman, I have searched the Internet trying to identify this crazy little bug. It was found under the covers of a bed that’s not used very often. It has little hairs all over its carrot shaped body and long grey hairs that protrude from it’s hind section. Turned over, it looks like six legs near the widest part, or head section. I could only see these features with a jeweler’s loop. I would say the bug measures 3/64” wide x 1/4” long half body half tail. Thanks for the help

Carpet Beetle Larva

Dear Bugman,
Just yesterday we posted another image of a Carpet Beetle Larva.  We believe your Carpet Beetle Larva is the larva of a Black Carpet Beetle in the genus
Attagenus based on this image posted to BugGuide.
