Driftworms are fuzzy purple caterpillars around the size of a thumb.
Driftworms have long bodies with no visible eyes. They have many pairs of legs, and their fuzzy bodies are coloured a purple colour. They are the larval form of a type of huge night-flying moth that glows in the dark.
Driftworms live in the upper branches of trees. They spin gossamer parachutes of silk, allowing them to glide on the wind to wherever it might take them.
