Large Midget in Snowberry



I found seven mines of Phyllonorycter emberizaepenella at Cromwell Bottom last Tuesday (16th) feeding in Snowberry. It's not straight forward separating them from the Honeysuckle Midget (P. trifasciella), both of which will use Honeysuckle as well. However, prior to pupating the Large Midget larva spins a rugby ball shaped cocoon which is olive green when fresh (see below) whereas the Honeysuckle Midget doesn't spin a recognisable cocoon.

I also have a couple of mines on my spindly little Honeysuckle bush at home which look more like Trifasciella so I'll have to keep an eye on those.
