had a wasp in the green house this afternoon,,hubby chased it out,no way was i letting it share the hot chocolate he got for me,had 3 bees the other week,and a beautiful coloured butterfly,it was hibernating?,in the larger seed trays so just left it,i will remember about the sugar water,as i have in the past come accross the very big bees,that seem to be stuned,is good to have the info,to at least try it.
