mason/orchard bee

5945   Hi my name is Barb from Mission BC. We have been finding these fly like bugs on our window sills and bathroom counter. They have wings but are not flying. They are crawling around slowly. Are they a type of fly? Where are they coming from??

This is a bee, possibly a mason/orchard bee in the genus Osmia. These are cavity nesters, and may have overwintered in or near your home – see http://tinyurl.com/m9xuuc8 for details on their life history. Ed Saugstad, retired entomologist; Sinks Grove, WV.
