Which plant characteristic is commonly associated with slug feeding preference?

• A. Thick, waxy leaves
• B. Thin leaved leaves
• C. Rigid, tough stems
• D. Dark, leathery leaves

Answer: (B)

Slugs feed best on soft, easily penetrated foliage. Their rasping mouthparts scrape through leaf tissue, so leaves that are thin and tender are much easier for them to eat and digest. Thin leaved leaves provide the micro-diet slugs need with less energy expenditure, making those plants more attractive to them. In contrast, thick, waxy leaves have a tougher cuticle and tissues that resist grazing, rigid or tough stems are harder to chew through, and dark leathery leaves are typically tougher and drier, offering more resistance. So the plant characteristic most commonly linked to slug preference is thin, delicate leaves.
