In the process of watching these little bees at their work, I knocked a clump of dirt into the entrance of a nest. Not wanting to make thigns worse with my giant fingers, I decided to sit back, and see how the bee went clearing out her own nest
These little bees were in what appeared to be a semi-social nest, whereby one bee would gaurd the entrance of the nest until another came up from behind to relieve her so that she could go foraging. This seemed to happen every 15-20 minutes or so
