\nOur conker trees are under attack from a leaf-mining moth. The 'alien' species is eating the leaves, making them lose their lovely colour, become weak and brown. Don't panic, natural help is at hand with the beautiful Blue Tit, who eats the caterpillars. If you would like to help save our finest tree, then pop on to Dr Michael Pocock's project here to start keeping an eye out for trees under attack. Here at Wallography we are out this afternoon to help collect the data, in hope that the trees can one day return to their beautiful colours again.
