Egg-species recognition in cannibalistic hatchlings of the land snailsArianta arbustorum andHelix pomatia

Short Communications

Summary

Laboratory experiments were conducted to determine whether cannibalistic hatchling of the land snailsArianta arbustorum andHelix pomatia discriminate between eggs of the two species. Hatchlings from both species showed a significant choice for conspecific eggs and consumed on average 1 egg in 4 days. Eggs from the other species were only occasionally eaten.
