Sawfly Query

While at Llyn Fach, this afternoon (ever so slightly in West Glam), I came across this lone Sawfly larva, on a small Birch sapling. What struck me were the colour and the glossiness of it.
I've been looking online and am fairly sure it is Craesus latipes, but would welcome some confirmation on that, please; especially as there is only one Welsh dot on the NBN Gateway map.

  1. Graham Watkeys has also seen this in the same area recently (posted on Facebook) and came to the same conclusion re the ID.

  2. There was only one of it, so I wonder if it is the same individual that Graham saw? Thanks for that info, George. The previous (first) Welsh record was for Ceredigion in 1973.
