Lots of these on Tilia in Harby churchyard the other day (24/09/2021). Are they identifiable?
TIA,

Re. hoverfly larvae
Syrphus sp. I think. There's a nice guide to hoverfly larvae in the Files section of the above group (df_1_9_Hoverfly_Larvae (original corrected).pdf)
I expect the UK Hoverflies Larval Group could do it: https://www.facebook.com/groups/1580298322233838
