The #decollatesnail, scientific name Rumina decollata, is a medium-sized predatory land snail, a species of terrestrial pulmonate gastropod mollusk in the family Achatinidae. It is a European species that has been introduced in a number of areas worldwide.
Sexual maturity occurs at approximately 10 months. An adult is capable of laying 500 eggs in its lifetime. The eggs are deposited singly in the soil and hatch within 10-45 days.
Rumina decollata is a voracious predator, and will readily feed upon common garden snails and slugs and their eggs. The snail eats plant matter as well, but this generalist predator is indiscriminate in its feeding and has been implicated in the decimation of native gastropods (including non-pest species) and beneficial annelids.
Decollate snails are tolerant of dry and cold conditions, during which they burrow deep into the soil. They are most active during the night and during rainfall .
