Leopard Slug
Limax maximusAlso known as Great Grey Slug, Tiger Slug
Leopard slugs travel through damp gardens and woodland floors under cover of darkness, feeding on decaying plants, fungi, and even other slugs. Adults perform a dramatic mating ritual, suspending themselves upside down from a tree branch or wall on a thick strand of slime. Their bold black spotted patterns provide camouflage against dappled leaf litter while warning away potential predators.
