reclaiming the beeless bee tree

the debauched and defiled mason bee house has dried pout enough that i am no longer concerned about mold inside it so i stuffed it full of reeds again, swathed it in chicken wire, and put it back in place in the locust tree...the leafcutter bee house in the bottom photo is unscathed thus far...whether there are any local bees that may indulge themselves in a new home or if the leafcutter bees will utilize it when ( and if ) they hatch out is beyond my knowing...but that won't stop me form offering the opportunity...there may be some research soon on methodologies of attracting solitary bees...putting out a "vacancy" sign...more if anything pops up
