Tenthredopsis litterata
This was one of two similar individuals flying around an Oak tree. It wasn't far from where I had found what I identified as Tenthredopsis nassata on almost the same date in 2020, so I imagined it would be the same species, although there were differences in its appearance. Keying it out to make sure, I realised it fitted litterata better (though I wouldn't have described any colour on its head as white so I wasn't sure) and I confirmed this by examining the penis valve.
