Seem to have a lot of pollen beetles about this year. No shortage of courgettes.

Nice pic Digeroo - never had those critters before. Can they badly affect the plant?
So that's what they are! My evening primroses are full of them at opening time.
No they are great. Pollinate the courgettes.
Until you pick a bunch of sweet peas and then they drop out all over the dinner table. ;D ;D
