Insects and Spiders

I don't know if this was similar to me but I was sat on a wooden bench on hols in Dorset and these tiny almost grain like fukers kept trying to take a mg of flesh. Like a splinter of wood in appearance...

First thought was an antlion larvae but think they’re only found around Suffolk in uk. They’re normally only found in their pits though, and think the abdomen is normally a bit more chunky though and this looks quite flattened?

Edit - at a guess id think it’s prob a larvae of a species of lacewing?
