I found this little guy on my coffee table.  He is about half an inch in length.  Pics are attached.  Hope you can identify him for me, please and thank you :)

Dear Anne - This is a caterpillar of a moth in the family Geometridae. This is a very large family, and there are quite a few species whose caterpillars have an appearance very similar to yours, so I cannot offer a specific identification. These often are called loopers or inchworms because of their peculiar mode of locomotion; they lack prolegs on most abdominal segments and thus cannot crawl like most other caterpillars.

Hope this helps,

Will accept most questions in general entomology, including those related to medical entomology, taxonomy, ecology, arthropod surveillance, and pest management. If you are requesting a 'mystery bug' identification, PLEASE either attach an image to your question, or post an image on a web page (such as Flickr) so that I can look at it, as verbal descriptions frequently are insufficient for a definitive identification.
