Mason bee females beginning to nest, April 2012

Here is a little video taken a few days after the first video.
Instead of seeing bunches of eager males buzzing around focused on last year's tubes from which the females are beginning to emerge, in this new video we see females intent on choosing tubes to begin laying in. There are many horn faced mason bees and quite a few eastern Blue Orchard mason bees as well. Most of the bees you see now are the females, having mated already and beginning their nesting activities. The females are a bit larger and heavier than the males. Males have long antennae and sometimes a little white mustache!

More females will continue to emerge from the old tubes for another week or two, and there are males loitering around the area hoping for that! But the bees in the video that are actively rushing in and out of the new tubes now are almost all nesting females.
