Can you identify this insect? If you zoom in on the pic you can see more detail
The insect moves like a caterpillar had many legs and what looks like hair on the rear and its head is red and can go in and out of its body like a turtle
This is the larva of a dermestid beetles, sometimes called carpet beetles. See http://www.livingwithbugs.com/carpet_beetle.html for pictures. Nowadays the larvae most often infest stored foods but fabrics can be damaged as well. Post a follow up if you have questions.
I can answer questions in any area of entomology (study of insects, spiders, mites, ticks, and other terrestrial arthropods). Contact me about home and garden insects, insects that bite and sting, and insects that damage homes such as carpenter ants and termites.
