I found this creature crawling round, I'm not sure what type of caterpillar he is so I gave him the benefit of the doubt, hide him under a broken pot to keep the birds away and he eventually disappeared. I hope he'll survive as it seems quite early for him to be out.
The house is quite springlike too since my hyacinths are finally and fantastically flowering. I bought these locally, they cost less than £1 for 4 bulbs and are perfuming the house better than any overpriced scented candle. I nearly didn't plant any hyacinths this year, these were a late purchase and I really wish I'd bought more as they can be planted in the garden when they finish and will produce flowers on a smaller scale each year. I tied them up with some left over Christmas ribbon, much nicer than string, almost a present.
