Yeah I'm not sure why they've been so interested in the pears. It's primarily before 11 - 12 after that there are plenty of different types of bees on the pear, but the honeybees seem to loose interest. It's not like they don't have plenty of other nectar sources right now. dogwood, redbud, apple, plum, apricot, cherry, dandelion, etc... I really missed the pear last year. Normally this tree is so packed with fruit that you have to worry about the limbs breaking, but last year that late hard frost killed the blooms and buds of almost every early blooming fruit bearing tree in the area.
