Found crawling on my mattress; about 1 mm (?). I've been getting bitten -- could this be the source?

Der Susan - The first image is that of a plant bug of some sort (possibly in the family Miridae), and would be very unlikely to be the source of your bite symptoms. However, I cannot see any details in your second image that would allow me to even begin an attempt at identification. Unfortunately, it is nearly impossible to determine the cause of 'mystery bites' without actually catching seeing something in the act of biting.

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.
