Water Dock with Additives.

Michael O'Hara and I spent a wonderful day out in the Norfolk Broads yesterday in the company of Tony Davis from Butterfly Conservation and various bods from wildlife organisations in Norfolk. For me it was like returning home as I once lived in Acle and the place we met up at was our go to site for Grasshopper Warbler and Little Owl back in the day. We were all there to scrutinise the dead stems of Water Dock and we were looking for the larval cases of a rare micro moth, Coleophora hydrolapathella (Water Dock Case-bearer). Tony had visited this site on previous occasions, including once on New Years Day, those BC guys are so "rock and roll" :-) After giving us a little introductory talk, risk assessment blah blah blah, it was into the field. Well in this case the swamp,  juncus tussocks with interesting gaps between them,  some shallow and some DEEP!!!. Luckily, Tony had been there for a while when we all turned up and had already found a larva. We all duly noted it then spread out like a group of kids on an Easter Egg hunt. Soon, excited cries of "Got one" began to ring out over the area. All progressed with decorum until one person discovered a stem with two larvae on and all hell broke loose :-) A couple of people then found stems with three on, "Game on". As we reached the end of our sweep across the swamp, on almost the last stem, I spotted one then two then three and then FOUR!!! larvae. To cap it all, the person who was with me then spotted a fifth hiding cunningly round the back of the stem. We left the field victorious, if a little wet. Apart from a great afternoon out, the people who attended will now spread out across the Broads and probably quadruple the known sites for this rare BAP species. Tony has threatened to have me strip searched before I go back to Shapwick NNR, with its huge amounts of Water Dock but no Coleophora hydrolapathella. I will be looking there over the next few weeks, will he ever believe me if I find one :-)
