Mummificering van slakken op betonmuur, 2

Mummification of snails on a concrete wall, 2. A few years ago I noticed how a concrete wall functioned as a snail trap: 466 slugs and 37 snails were found adhered to a vertical wall in a dried out, creeping position (Mienis, 1994). It appeared that Woodward (1906) had made a somewhat similar observation already 90 years ago. According to his opinion this phenomenon is caused by dry cement. In the autumn of 1998 I passed several times the same site where I made my observations in 1994, not a single slug or snail mummy was noticed this time. The reason: in the meantime one had coated the walls with a thick layer of paint.
