brown caterpillar

[Tog]

Found this little chap right outside my front door. nearly stood on it.
i gave it a tiny poke with an old soft leave and there was a tiny bit of movement so i have scooped it up and brought inside. Clearly being warmer inside it has perked u and is moving a bit and gripping the old leaf now.

Would someone tell me

a) what is it?
b) what should i do with it?

It was on my block drive no where near any plants in fact the closest garden is about 50 yards away.

Should i keep it inside in a tub with soil leaves eyc or shoud i just put it back out and et nature take its course?

Its a large yellow underwing Noctua pronuba a very common species of moth which eats a wide range of plants often within lawns and rough grassland. They spend the winter as larvae, so the best thing to do would be releasing it back into a suitable area of habitat. Keeping caterpillars like this over the winter can cause more harm than good as you actually raise its metabolism which results in a speeded up metamorphosis. This means that it turns into a moth far to early then there is insufficient nectar(food), its too cold and no other members of the species are active so it can't breed.

Thank you very much for the id and advice. I will return it to a grassy area and leave it be.
