Gordon Hart writes: This giant sawfly has been in the same area of our Highlands yard for the past couple of weeks. It perches on a leaf for extended periods with short flights ending up back on the same spot. It is a large and heavy-set, at least 30 mm long, and with large pincer jaws. I have attached two photos: one a dorsal view, and one showing the large jaws.
