I would like help identifying this bug.  We are in Uruguay South America.  Iíve attached two of the best pictures I have of it.

Thank you!



Let me say at the outset that I'm not an expert in Uruguaian (sp?) insects. But, this appears to be the larva of a dermestid beetle (carpet beetle), see http://www.livingwithbugs.com/carpet_beetle.html for more images. They infest dry foods but are otherwise harmless. If you tell me a bit about how it was caught, what it was doing, I may be able to confirm.

QUESTION: Thanks for the rapid reply. We live in a 100 year old apartment/church. There isn't any carpet, just tile and old plaster. We have seen and killed many silverfish here. My wife places diotamaceous earth under and around the bed. So, the bug may have lost legs in the process of crawling through the dust. We found the bug dead on the sheet when making up the bed. We noticed the pointed parts coming from the hind part of the insect. She wants to be 100 percent sure that it isn't a bed bug :)

Thanks again,

It is not a bed bug (see http://www.livingwithbugs.com/bed_bug.html for pictures of bed bugs). The hairs on the back-end are characteristic of dermestid larvae. Carpet/dermestid  beetles are very common and usually not a big concern unless they infest stored food.
