Mature grotworms are monsters that can be found on the bottom level of the Grotworm Lair. They have slow, but extremely accurate, magic and melee attacks (It should be noted that, due to the recent changes of the combat system, these grotworms are no longer especially accurate or dangerous for players with a combat level of 160 or higher). However, magic attacks are only used on players outside of melee range, similar to monsters such as metal dragons and cockroach soldiers. It is possible to safespot them using the pillars if you stand far enough back from them. Lower-level players are recommended to bring high healing food such as monkfish or sharks. Ranged/magic would require Protect from Magic/Deflect Magic if using safe spots. The magic attack has a short range, so flashing your prayer when out of its range can help conserve prayer points. Despite their ranged weakness a player with 70+ melee stats should have no trouble killing them efficiently, even without the use of prayer.
Using high level ranged gear such as Armadyl and using a bunyip will mean you won't need prayer pots/flasks. Due to the occasional shark drops, at most you should only need 1 or 2 pieces of food as your gear will mean little damage from the mature grotworms magic attack while ranging.
Some players may find it useful to bring runes to cast High Level Alchemy on the items dropped by the grotworms, as adamant and rune equipment are common drops. The profit of using this spell on some of these items is greater than banking and selling them.

Rare drop table dropsEdit
|Show/hide rare drop table|
- When these creatures were first released, they did not drop items from the rare drop table, but did after the Queen Black Dragon update.
- The word 'grotworm' means caveworm in Dutch.
- Their examine text hints towards the possibility of the existence of a stronger grotworm based creature, although likely not an actual worm as "metamorphosis" implies, but none were released with them.
- Due to excessive botting, an update on 7 August 2012 removed several rune armour drops from the drop table of mature grotworms, replacing them with their adamant counterparts, making it less effective to earn money. The same update also removed royal bolts from their drop tables.
- Although their Attack level is 1, they attack with fairly accurate melee attacks being able to do 300+ easily even with the use of good armour.
