A sunny day like a jewel in a dull, cold winter. For the first time in months I venture out to do some gardening. There are little signs of bug activity. A few 7-spot ladybirds sunbathing; a cloud of winter gnats; a bluebottle which rapidly gets into the house through the back door...I moved an old tile left leaning against a south-facing wall and found a gathering of overwintering snails stuck to the tile and the wall. A few small ones, but mostly of them grown up snails, shell against shell. In this spot they keep relatively warm and dry during the winter. The snail secretes a specially tough mucus to seal its shell opening which can glue it to walls, or other snails.
