While many of the fruit trees and bushes in the garden are a magnet for bees, I never see many (or maybe not even any) bees on the redcurrant bushes. I occasionally see wasps visiting, and sometimes little flies. But the only insects I see regularly visiting the redcurrant flowers are ants.
I’ve always thought the ants must be helping with pollinating the currants. But, reading around the subject, it seems they might not be very useful as pollinators at all. However, I always have plenty of fruits set, so I’m still inclined to think the ants are helping, at least somewhat.
Less helpful are the ants’ aphid farming activities. Spring has come so early and been so warm this year that not only are the redcurrants already setting fruit, but the aphids are already reproducing rapidly. And the ants are busy stroking and defending “their” aphids.
The only thing that is slightly helpful about the ants’ affinity for the aphids is that their presence helps to highlight where the aphids are hiding. I rub the aphids off as and when I see them, but given what an early start they’ve made, I think this might become a bumper year for aphids.
