Ectoedemia hannoverella mine in Black Poplar

The scan below is of the leaf mine of Ectoedemia hannoverella in a leaf of a black Poplar sp. This species was found new to Bedfordshire near Arlesey in November 2009 and was also found at that site in 2010. This leaf is from Chicksands Wood on 30th October 2010 and is the second site in the county for the species. Please look out for the characteristic mining pattern in the leaves of Black Poplar and report any to David Manning - with a photo for confirmation.
The adult moth lays the egg on the petiole of the leaf where it forms a gall by initial mining and then mines out into the leaf blade leaving a characteristic green island area once the rest of the leaf turns yellow. Scan by Andy Banthorpe

I really love all the amazing images but I'm afraid of spiders. I've never met a spider I got along with.
