Eggs of the garden slug, Arion hortensis, photographed five weeks after they were laid, August ( Norfolk UK ).Slugs are members of the Pulmonata within the class Gastropoda; they breathe air through a rudimentary âlungâ within the mantle. The eggs of A. hortensis are laid in batches of 20-50 in damp situations and take a few weeks to hatch at normal ambient temperatures in late summer. A. hortensis is a widespread pest of gardens, feeding on tender foliage. The picture shows a batch of eggs of A. hortensis that was laid in the soil within a flower pot. The eggs are 5mm in diameter. There are eleven recently emerged baby slugs in the picture, together with empty egg cases and eggs as yet unhatched. It will take one year for these slugs to attain full adult size.
