About 3mm - overlaid by web - so focusing difficult - and feeding on a fly.
No interactions present.
The fly being eaten looks like a Dolichopodid fly.

Oh! - thank you for that. Shame there isn't a spider that eats that particular fly!! - it would be easier to identify then!But will make a note of it anyway...
