Garden Snail (Cornu aspersum)

The garden snail is a widely known plant feeder, causing significant damage to crops and ornamentals. Introduced to California in the 1850s for its culinary value, it has since thrived and become a challenging pest.

With a thin, large shell sporting yellow or brown hues accented by fine wrinkles, it adds a distinctive touch to our gardens. Color variations are common, resulting in a visually diverse population with four to five whorls featured on adult shells.

Originating from the Mediterranean, its territorial expanse now includes northwest Africa, Iberia, Asia Minor, Egypt, and even Britain. Courtesy of human influence, it's found globally in places with temperate climates.

Primarily herbivorous, the garden snail isn't a picky eater. It feasts on various plants, from fruit trees and vegetables to rose bushes and garden flowers. It also scavenges on decaying plant matter and crushed fellow snails.

Most importantly, this mollusk forms a vital part of the food chain, eaten by various creatures. Many birds and small mammals benefit from this unassuming trespasser's presence.
