Yesterday I did a search for V-moth larva on the Norfolk bank of the River Waveney opposite Beccles Marshes where I have recorded the adult moth over recent years. Searching for about 20 minutes in a relatively small area among the wild redcurrant turned up 7 larva the largest about 30mm long, so possibly in its final instar. The wild redcurrant is spread throughout this vast woodland in the very wet areas, about 90 per cent of which is virtually inaccessible as it is more akin to a flooded jungle. Good indication that at least on this site there is at the moment a healthy population of this increasingly rare moth.
