The diversity of Hyalaeines in your garden is amazing, but I wonder how effective they are as pollinators since I never see loose pollen grains on their bodies unlike the hairier bees
Long grass, piles of sticks, leaf litter and a continuous supply of flowers seems to create the right environment for a good range of species, but I do agree the Hyalaeines don’t seem to carry their weight as pollinators, any transfer of pollen would be exceptional I think
