Agapostemon virescens - female

Agapostemon virescens - Female

Surprised to hear that these bees live in Oregon. Everyone I've talked with has never seen a green bee. This was the only bee of its kind when I took this photo. I returned 3 times since and it is still the only bee of its kind in the same spot. Are these bees loners? Our altitude is 3500ft, we used to have severe winters, but they are milder now. It is normal for our area to be dry all summer - more like the Oregon deserts, we do not get lots of rain like the coastal towns in Oregon or the year round 60-70 temperates. Could this little female be part of a migration due to weather changes?

These bees are communal nesters. Several females will use a common burrow entrance (usually "guarded" by one female), but each female makes her own cells and provides for her own offspring. These are actually common bees, but not usually seen by the casual observer. Look for nests in bare patches of soil in lawns. They are widespread in their distribution, also. I saw them in Portland when I lived there.

Thanks for the interesting info on these pretty little bees. Seeing the same bee in the same area, on the same group of flowers now makes more sense. Although your comment about seeing these guys in the Portland area makes me remind you that we are talking clear across the state near the Washington, Idaho, border in the Blue Mts. It is a world of difference when it comes to climate, winter, and moisture. Also the flowers do not bloom until atleast March(That would be Tulips. Most flowers start blooming around the middle of May. All flowers are gone by the first of Oct. excluding the die hard Asters. Thanks again for posting your comment.
