Breathing of aestivating snails is reduced and the body water content falls to a lower value. During long periods of continuous dryness resting is uninterrupted. Heavy summer rains can trigger activity and snails leave their resting places for a short time before resuming aestivation as conditions become dry again. Short periods of summer rains are not sufficient to trigger maturing of reproductive organs and mating . This can lead to sever mortality in the population.
Snails become active and move down from their aestivation sites.
Snails start feeding , their reproductive organs mature and they copulate. Egg laying is most commonly observed between April and July but breeding can continue until September. Numbers of eggs in a cluster vary for each species. A snail can produce up to 8 clusters in a season. Newly hatched snails are about 1.5 mm in size and hatch 2 weeks after the egg cluster is laid.
