Yellow Slug

Yellow Slug Introduction

Like all slugs, the yellow slug moves slowly using a gliding back and forth motion. It has a foot on its abdomen that creeps along, aided by the secretion of mucus, which leaves a slime trail. Yellow slugs are mottled yellow and gray with two sets of blue antennas. The top antennas sense light, while the lower ones provide a sense of smell. 

Yellow slugs live primarily in the United Kingdom, including Ireland, Scotland, Wales, and England, as well as Western Europe. They have moved to other places such as China. 

These medium to large-sized slugs eat fungi, vegetables, and decaying plants and bark. They’re considered pests because of the damage they can do to gardens, but they break down nutrients in plant matter so it can be used again.
