Dung kalphites are kalphite larvae that roll dung. They are found in the Kalphite nursery during and after the Diamond in the Rough quest. Unlike the kalphite larvae in the main Kalphite Hive, dung kalphites can be interacted with: players can use a slashing or stabbing weapon to slice the dung ball they're pushing, yielding mostly minor rewards. The kalphite will then flee. Off-hand weapons do not work for this purpose. These do not count towards fulfilling a Slayer task for kalphites, as they are not killed - they simply burrow back into the nursery.
A few rare beetles can be found that sparkle and make bell sounds. These can be used to help locate the ones with rare loot such as rubies, diamonds, grimy ranarrs, and potato cacti. They spawn rarely per world (3 - 5 mins) and each one drops double of the loot of the non-sparkling counterparts, for example two ranarrs/potato cacti instead of one or six ugthanki meat versus three.
At the end of Diamond in the Rough, it is revealed that the dung kalphite that took the diamond was sent by Scabaras to try and stop the player and Ozan from delivering it to Lady Keli, later revealed to be Amascut, the Devourer.
