I like the idea of a BlackflyFriday so here is a Black Fly on a dock leaf. Not a brilliant photo but the best I could do at short notice. (1st June 2024)

Apparently it is #BlackFlyDay (I think that's what it's called 😛) - here's a lovely velvety black hoverfly, Pipiza species (probably P. noctiluca) from Somerset last spring

My favourite for #BlackFLYday

One of the WORST examples of AI a this ‘black fly’ generated for a Vets blog post is a whole lot of wrong.

Stick to real insects folks - we need them
