Happy Pollinator Week! Today in the Cherry Creek Pollinator Habitat the leaf cutter bees are very active. I can see where they have visited a seedling ash tree. Each disc of leaf that is clipped will become part of a cell that houses an individual leaf cutter bee egg. One of my favorite things to do is to check the bee house each week to see how may drilled blocks have been filled.
