Given that you found them beneath grass, they are most likely chafers. Had they been present in any quantity you would not have needed to dig holes in your grass (as the grubs would have destroyed the roots and it would be a loose mat!) so I wouldn't worry too much. An infestation of them can bring in corvids and badgers in country areas, which can rip up the affected grassland or lawn, turning exasperated gardeners into carpet layers, day after day, after day, after day........
That's put me off my breakfast @Dovefromabove Like @Mossbank, I'd have said more likely to be chafers. Not something I've ever had though. If the grass is ok, I don't think you've got too big a problem.
Have you seen any crows/magpies etc getting stuck in? They love leatherjackets too.
It's a place where beautiful isn't enough of a word....

This is under my main lawn, I’m planting conifers. The lawn has a lot of thatch if that’s relevant, and used to have a fair amount of moss.

I suppose there’s nothing I can do either way, in any case.
