Megachile apicalis, a species introduced from Europe and a close relative of the alfalfa leaf-cutting bee, has made its way to Colorado, and what a stunner she is! We reared this bee from one of The Bees’ Needs 2013 bee blocks that was located in Golden, Colorado. This individual was just recently identified, adding yet another bee species to our ever growing Colorado list.
It will be interesting to watch over the next few years to see how, or if, it will move across the state. You can check out its worldwide distribution (minus a Colorado dot that has yet to be added) at http://www.discoverlife.org/mp/20m?kind=Megachile+apicalis .
And in case you were wondering — this species uses several overlapping whole leaf pieces to plug their nests, similar to our ever popular and also introduced, alfalfa leaf-cutting bee.
