Here is a shot of a larva stage of the Fool's Gold Beetle (Aspidomorpha tecta) that I posted yesterday.

Fool’s Gold beetle larvae do not discard the shed skins from moults but instead pile them up into a tail on the tip of the abdomen together with some of their excreta. Larvae wave this tail around when disturbed so possibly it is used for warding off predators and parasitoids.

Wow! What an education!
