Scarab larvae are baby Scabarites found in their hive beneath the ruins of Ullek, first accessed during Dealing with Scabaras. They are fairly weak in combat themselves, but seeing that the dungeon also contains many powerful adult Scabarites and traps, killing them is effectively more dangerous than it seems. They cannot be killed for the Scabarites slayer assignment. They do count for the Menaphos City Quests.
