I wasn’t sure the mason bees would take to that spot behind the shed, even though it’s perfect as far as I can tell. Those little mud packs mean the female bees agreed, and found it an acceptable place to lay eggs.
Mason bees are docile, good-tempered, don’t sting–not that bees will sting me anyways, we have an understanding–and are wonderful pollinators. Which means more crops for me, and that my flowers will feed several little buzzing workers. This, my friends, is a gardening victory.
