I recently found what looked like a large ant hill in my flower bed. I have since seen a flying insect coming and going from this mound. It is 1 to 1 1/2 inches long, fairly thick bodied, and has black, rust and yellow colorings. I have noticed this insect flying low over the lawn on several occasions. I live in central Maryland, if that's any help. Any idea what this insect is? Thanks.

If you can put a picture on Flickr, Twitpics or Picasa and post a link here we might be able to help. In addition try
