Dryophilocoris flavoquadrimaculatus is very common on and around oak. It can be seen sucking on both plants and insects. Reaching some 6 or 7 mm in length it is much smaller than the previous species. The adults appear for a short time only and are seen in May and June mainly. It has a burden to carry: a long and complicated scientific name, meaning something like 'yellow four-spot'. A common species all over Europe and Northern Africa and, as far as we know, very common in Britain and Ireland as well. Even though Dryophilocoris flavoquadrimaculatus is quite easy to identify, you have to pay close attention, as there are quite a few similar black and yellow species.
