The normal habitat is similar to that of R. pini, but rather more humid. Dicyphus pallidus (H.-S., 1836): on 18thJuly 2009 Rob Ryan found dozens of macropters & brachypters of a constrictus- sized Dicyphus on Hedge Woundwort (Stachys sylavticus) in Homefield Wood near Medmenham (Bucks, VC24). Ap- parently ‘not right’ he put them aside until recently when he sent a male & 2 females to me. I recalled that D. pallidus is widespread in The Netherlands, so I checked this in Wag- ner & Weber, & found that the bugs fitted this well, notably the black pubsence of the upperside & black bristles along the underside of the hind femur.
