I have been keeping an eye on the birches where I first spotted the second instar nymphs and have managed to get a photo of final instar nymphs a week ago and today a number of adults. It seems that the adults photo is a little special as a couple of experienced recorders of shieldbugs have not seen adults crowded together thus on a leaf. I have only found one other similar photo on the internet so it would seem that not many people get to see this as the adults split up quickly it would seem and I am rather privileged to be one of those.

Also seen today 3rd and 4th instar Birch Shieldbug nymphs.
