Weird bug
This thing is about half an inch long, and there were two of them, in an old cream-cheese lid…. I had picked it up to throw it out, but got distracted and put it down next to me, and then I noticed the pieces of dirt were moving…. not only that the worm like thing can come out of either side! Anyone know what this thing is? One of them escaped, but I got photos of the remaining one….. he was about to crawl off of my workbench, but I caught him…they seem very aware… the worm part doesn’t come out unless you stop moving.

This is a Case Bearing Moth Larva. We get blurry photos and pumpkin seed descriptions all the time from all over the world. Your photo is quite exceptional.

Regarding the “case bearing moth larva” posted 04/10/2007); you might want to add that these insects also go by the names “household casebearer” and “plaster bagworm.” Most of these found in the United States likely are in the genus Phereoeca, but the genus Praececodes also has been reported from the southern USA. See http://creatures.ifas.ufl.edu/urban/occas/household_casebearer.htm for more detailed information.

ahh!!
Hi, I was cleaning out my room, sort of spring clean when I found out these were all over the place, below the bed on the carpet. Most of them were underneath boxes and underneath chests of draws. A closer inspection could see that some were wriggling, worm like creature with small brown heads, that were popping out of the pods as shown. Im kind of feeling quite sick now, never had them before, what are they? where do they come from? how do I humanely get rid of them? About 6 months ago I had purchsed a new mattress could that be the cause? I did look on your website but cannot find anything that resembles what I found. I have enclosed a photo.
Thank You
Dave

Hi Dave,
You have two different insects. In the center is a Dermestid or Carpet Beetle Larva. The cocoon are some type of moth. We checked with Eric Eaton and here is his identification: “Looks like casemaking clothes moths, Tinea pellionella, or webbing clothes moths, Tineola bisselliella. family Tineidae. I am no expert, but that is what I suspect. Really curious what is under the bed, though:-) Eric”

Mystery bug
I live in Guernsey Island, just off coast of Cherbourg peninsula. I have just seen a bug which looked a bit like a tiny hermit crab. It was a little larger than a grain of rice, and it’s shell or cocoon looked to be composed of tiny grains of grit and sand. A head and legs were just visible as it crawled along the top of a granite wall. Other cocoons, stationery, appeared to be fixed in crevices in the wall. Looking in books, I found it resembled a caddis fly larva – except it was not in water. I took a picture, but it is almost impossible to see the bug, as it matches its background so well. So here is my drawing. I’m intrigued as to what it might be.

Hi Mike,
You have Casebearing Moth Larva, Phereoeca fallax. They are harmless, and often feed on fallen pet hair. Your drawing is pretty great. You can see photos and get more information by visiting our clothesmoth page.

Hi Bugman!
I was going to email you with my pictures of this bug that I have found twice on the walls of my home in Southern California but fortunately found the ‘Case Bearing Moth’ email on your site. Thanks for solving my riddle! Here are my pictures if you’d like them for your database

Little worms in white paper houses
Dear Bugman, I recently moved to Florida to a just constructed home. I have a monthly bug service that I pay for dearly, as our new home had cockroaches before it was even occupied. Now I keep finding a very strange bug in my bathroom. It is a little tiny reddish worm carrying a big (1/4 inch long) paper shell, acutally dragging it around. The shell looks similar to a large sunflower seed in shape, but is white and papery. When you go near them, they retreat into the little shell. Then when they think it’s safe, they pop out of the end and start akwardly dragging the shell around again. I keep picking them up and tossing them outside, but everytime I go into my bathroom there are more of them. Yesterday when I was taking a bath, one crawled up out of my bubblebath, pulling his little paper shell with him. Now that’s the last straw for me. Yuck! What could these things be? None of my neighbors have ever seen or heard of such a thing. They suggested silverfish, but I know what they look like and these definatley are not silverfish.
Help!

Hi Leslie,
You have Case-Bearing Moth larvae. The small larvae carry a noticeable case made of fine sand and debris. The case, which is about a quarter to half an inch long, is flattened on top and bottom, expanded at its center and tapered at both ends. They are often found on walls (both outside and inside) of houses and other structures. Larvae are said to feed primarily on insect remains, fur, flannel, and hair: they do not seem to be a clothes pest. We have gotten many letters from Florida regarding Case Bearing Moths.

Hello,
We are writing to you on behalf of Leslie M*^^!##s. She has asked us to contact you to see if you will consider removing the content about her … Please allow us to introduce ourselves. We are ReputationDefender, Inc., a company dedicated to helping our clients preserve their good name on the Internet. Our founders and employees are all regular Internet users. Like our clients, and perhaps like you, we think the Internet is sometimes unnecessarily hurtful to the privacy and reputations of everyday people. Even content that is meant to be informative can sometimes have a significant and negative impact on someone’s job prospects, student applications, and personal life. We invite you to learn more about who we are, at [web address removed] . When our clients sign up with our service, we undertake deep research about them on the Internet to see what the Web is saying about them. We find sites where they are discussed, and we ask our clients how they feel about those sites. Sometimes our clients express strong reservations about the content on particular websites. They may feel hurt, ashamed, or “invaded” by the content about them on those sites. As you may know, more and more prospective employers, universities, and newfound friends and romantic interests undertake Internet research, and the material they find can strongly impact their impressions of the people they are getting to know. When people apply for jobs, apply for college or graduate school, apply for loans, begin dating, or seek to do any number of other things with their lives, hurtful content about them on the Internet can have a negative impact on their opportunities. At some point or another, most of us say things about ourselves or our friends and acquaintances we later regret. We’re all human, and we all do it! We are writing to you today because our client, Ms. M*^^!##s, has told us that she would like the content about her on your website to be removed as she considers it outdated. Would you be willing to remove or alter the content? Simply omitting her last name would be more than sufficient. It would mean so much to Ms. M*^^!##s, and to us. Considerate actions such as these will go a long way to help make the Internet a more civil place. Thank you very much for your consideration. We are mindful that matters like these can be sensitive. We appreciate your time. Please let us know if you have removed or changed the content on this site by sending an e-mail to: [email address removed]. If another individual would be more appropriate to contact on this matter, we’d be grateful if you could forward this message to him or her. Yours sincerely,

Hello Bistra,
Though it is time consuming, we can provide a do-over for her by removing Ms M*^^!##s name from our website post haste. We never intended to invaid her privacy. We merely posted a query letter she willingly sent to our site. We would hate to impact her potential dating opportunities, her chances of getting into a university (we would never forgive ourselves if this was a deal breaker with Harvard) or her chances of getting a lucrative job merely because of the world knowing that she had Case Bearing Moths in her bathroom. It is sad that potential love connections and employers could be so cruel and insensitive when a good look at their own closets, kitchen cupboards or bathrooms might reveal an infestation of carpet beetles, meal moths or bathroom flies. Our sympathies go out to Ms. M*^^!##s and we wish her all the luck in her subsequent internet romances, post graduate work, and securing that six figure income now that she cannot be connected to Case Bearing Moth Larvae on the internet.

Our readership weighs in:
On the ” Leslie M*^^!##s” thing.

I have a sneaking suspicion that this young woman probably had a problem with an entirely different place all together. Or perhaps had no problem at all and this company is phishing. Either way, they just did an internet search for her name and, since it came up on your site, they mailed you. That’s my opinion and can be taken as such. This sort of thing always makes me mail the person in question to see if it’s true. Bye! Love your site!

Dear What’s That Bug,
At first I thought that your letter from the ReputationDefender team was a joke since it was one of the funniest things I have read in a long time. Ironically, I think that worse than having your name associated with a picture of a Case Bearing Moth Larvae in your bathroom, is being associated with a “reputation defender team” trying to get your name removed from being associated with a picture of a Case Bearing Moth Larvae in your bathroom! Personally, I would feel honored to have my name as one of those privileged few who have had their pictures and/or letters posted on such a respected and loved web site. In fact, I wouldn’t want to have as friends or employers those who would think that writing such a letter to What’s That Bug would be liability. Some of the coolest and most interesting people I know are those who are frequent visitors to this site. Keep up the good work!
Laura from NJ

Can’t quite figure this one out…
Hello Mr. Bugman!
I love your site and you’ve done a great job cataloging and explaining to people what bugs they have been lucky enough to photograph or see. I searched and couldn’t find out about my bug. I suspect that it’s a bagworm but i’m not sure. I live in St. Petersburg, Florida in an older wood framed house. We have lived her for 2.5 years and i’ve never seen this insect until the past few weeks. I’ve seen probably a 8 or so. They are usually >crawling up a wall – inching their way up pulling this sandy very flat sack like thing behind them. In the photos I’ve attached, I placed in on my bathroom sink to get a better shot. He has some lint attached to >him from the baseboard. I didn’t measure this one but another one I just found is about 1/8″ and he was smaller than this one. I would appreciate any feedback if possible.
Thanks so much!

Hi Mo Eppley,

Ok this one is really gross. I live in Singapore. A couple of days ago, I looked down and saw this flattened rice krispie looking thing on my floor. I looked closer and it was moving. A tiny little brown head looking thing came out and helped it inch along. That head like thing could come out either end. The "casing" whatever it was looked like a whitich rice krispie. I think it was something the thing had excreted. I think it is a worm inside but I am not sure. Maybe it is something in its larva stage. Do you know what this sick looking thing is?
wendi in Singapore

Dear Wendy in Singapore,
There are certain moths that have a caterpillar that spins a cocoon like case that they live in. They can drag the case around. sounds like that is what you saw. The family, called Casebearers, is Coleophoridae.

thank you so much. It is difficult to find pictures but I did find one that is similar of the one that eats Larch. The one here is whiter casing but I think you are correct. I really appreciate your reply.
