I found several 'pairs' of spiders on silver birch trees in Roydon Common.
No interactions present.
I think these belong to the family Linyphiidae but hope some one could take the ID further. Photo 1 is female I think and 2 male. Several pairs observed on different birch trees.
Thanks for the ID and good point about the trees.
