I had nearly 100 Diamond-backs last night. No other migrants though.
Over 40 in mine at Roath.
Only 3 Diamond-backs here in Llandaff, also a Rhyacionia pinivorana, new for Garden. I'm still waiting for things to kick into gear. Last year Started around 11th June with the Striped Hawk. So any day now.
None in the box on Tuesday night in Creigiau, but I counted 17 in one of the flower beds early this evening ... pretty sure they weren't there this morning ... and also several others in the grass and other beds.
