Entomology (Study of Bugs)/Bugs in house

We just moved into a newly built house that has a soybean field behind it. There have been lots of little bugs flying around the house. They aren't near food, they are more in our living room and bathrooms. Do you know what they could be? Could they be from the soybean field?

Dear Tom - I must admit to being a bit puzzled by this one, as the image appears none too clear to me. Am I looking at the top or bottom of the critter? It looks more like a small fly, such as a vinegar/pomace fly (often erroneously called fruit flies) than anything else, in which case I would expect them to be fore abundant in the kitchen or other sites associated with food preparation. It certainly does not look like any alfalfa insect that I am familiar with. I realize that because of their small size that getting large, sharp images is difficult, but if you could try some more, it might be helpful. If the insects won't stay still, try putting some in the refrigerator for a while before photographing them.

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.
