Early stages: Mompha epilobiella

Plenty of larval spinnings around on various Epilobium species at the moment.  The larva is much lighter than that of M. conturbatella which also forms spinnings in this way.  Most of the M. epilobiella larvae I've found recently have been in terminal shoots, so you need to check the larvae closely to separate these two species.
