Caterpillar ID please

[Amari]

I recently planted some strawberries on the allotment and one plant has had nearly all its leaves eaten. I've consulted Collins Complete Guide to British Butterflies and Moths = poor - no guide to caterpillars. My Field Guide to Butterflies and other Insects has several pages of b'fly and moth caterpillar ID but none seem to match.
Brown with short hairs.
Four rows of white dots: two rows down the middle of the upper side & one row along each lateral side.
Apols for the poor pics - I didn't want to disturb it!

Brilliant James!
KGM (which I've never heard of) is not in the index of the second book quoted above but Collins Guide has an entry and, unusually, shows a pic of the caterpillar which matches perfectly. Mother moth looks very drab.
Please tell us more about your entomological mastery......

Ha! I wish! I happened to see a very similar caterpillar a short while back and had no idea what it was, so had to look it up myself.

That’s a nice looking caterpillar- I’m glad you didn’t disturb it!
