Tony, I don't think the bug is D. ruber. It's worth checking out Tristan Bantock's bug website http://www.britishbugs.org.uk/heteroptera/Miridae/deraeocoris_ruber.htmlCheersBarry
Excellent site!...thanks Barry. Appreciate your thoughts on a late record of D. flavilinea (adults June-July). It looks a better match to me.
I overlooked that one. Many thanks Dave.
