Campyloneura virgula is a common predatory bug found on a range of trees across the UK, particularly hazel, hawthorn and oak.
Males are extremely rare, raising the possibility that C. virgula might be parthenogenetic.
A distinctive marked species with very long antennae and a bright yellow cuneus, tipped with dark red. Nymphs are yellow, with red-banded antennae and a red stripe on the margins of the pronotum.
This one was seen in the gardens of Chiswick House in July 2023.
