Euura miliaris

Larvae found on regrowth of a Grey Willow chopped down two years earlier (and ignoring the Goat Willow with branches crossing over) - 136 larvae counted, apparently the first Norfolk record since at least 1888. I'm grateful to Andy Musgrove for questioning my original tentative ID and to Ian Andrews for confirming they were miliaris.
