Abstract

Helix texta is endemic to the Mediterranean regions of Israel. It has a seasonal activity pattern which starts in the autumn, with the first rains, and dwindles towards the spring, when the snails dig into the ground for a six months long aestivation. A cold spell of 0°C will, however, terminate the active season of the adult snail, even in the middle of the rainy season. Survival of the young is very low and most of them (90%) do not survive their first year, because of the winter cold and the summer drought.
