Default Odd Rasberry Problem

Yes, huge and black. Humidity has been dry this year and we have not
had too much rain in the last month either. It looks like it could be
a combination of all the above. I wish I could cover the rasberries
next year to prevent the black bees from comming back but then I risk
some pollination loss. Live and learn.

Huge and black? May have been carpenter bees. Huge and 'honeybee'
colored? May have been bee-imitating flies. Not the most effective pollinators
of raspberries. (I have been lucky to have had honeybees working my plants.)

Poor pollination can result even with plentiful bee visits if the relaltive humidity
is too dry. Too much rain during the flowering period is a problem as it limits
the number of bee visits.
