Melissa found these leaf mines of Phyllocnistis saligna on Crack Willow on the bank of the River Ouse at Great Barford today (14th). This is the only the second record of this species in the county and the first time the leaf mine has been found. The first county record was an adult caught by us at Chicksands Wood in 2010. The mine here is up the main rib of the leaf and also down into the petiole.
