Wildflower seeds pay off

In the spring I planted some wildflower seeds and I think this is Ragged Robin - but correct me if I am wrong. The Hover flies absolutely love it and the flowers are always covered in these funny little flies.
Went with grandchildren to my favourite nature reserve - Rimac. We saw dragonflies, baby natterjack toads, butterflies galore and a Marsh Harrier hunting.
So what do I blip but a flower in my garden. I have had several Holly Blue butterflies again and peacock and white butterflies are everywhere.
But I love this flower and the hover flies!
