Primrose

Ok so this plant looks pin-eyed, rather than thrum-eyed. Something to do with pollenation I am told.

primrose pollination

There is a whole collection of adaptations to ensure cross-pollination in primroses - there is a problem - how often do you see a pollinator visiting primrose flowers? I have spent too long watching in the past.

Darwin says
"the primrose is neve rvisited (and I speak after many years' observation)by the
larger humblebees andrarely by the smaller
kinds."

Primrose pollination

That's very interesting.Thank you. Has anybody studied the moths? Not easy I suppose.
I wonder how importatnt temperature is to the production of nectar in Primroses?

primroses

I have observed primrose at dusk/early evening when looking at slug grazing of anthers and did not see nocturnal visits by moths - it is possible that thrips transfer small amonts of pollen.
