I was in Byfield yet again. And again I had some time to kill - about two hours in fact - so I ambled over to the pocket park, confident that yet again I'd find something of interest. In fact before I had even reached it I had cause to bring my camera into action. A couple of Lombardy Poplars stand at the northern edge of Byfield's playing field and some of the leaves bore reddish swellings.
Poplar leaf galled by the fly Contarinia petioli, Byfield.
