Slug moths are a tropical family of moths who resemble slugs in the larval stage, earning them the name. There are over 1800 species, with even more possibly undiscovered.
Most slug moth larvae are green. They are relatively smooth, though some have urticating bristles which cause pain if touched.
Their bodies are flat with poorly developed legs. Locomotion involves secreting a form of liquefied silk as a lubricant.
The cocoon in which the caterpillar pupates after reaching its final instar is made of silk and hardened with calcium oxalate.
Sexual Dimorphism: Present but nothing too significant.
