Larvae are still very young, not yet capable of combat or anything beyond merely crawling on the cave floor. When the player enters a cave without a light source, they are attacked by small bugs; whether these are the cave bug larvae or another species of insect is unknown.
- On an older layout of the official RuneScape website, cave bug larvae often appeared on the home page next to recent updates.
