Beetles with horns

To me beetles with horns are especially fascinating (and cute). Only recently I realised that this feature is not restricted to one family nor do all beetles within a group have it. To get an idea of the number of species and variability of the horn(s) I've decided to start this traditional project.

And, yes I am sexist (sorry): females of the same species which don't have a horn are not allowed here.

I define a horn as a pointed structure protruding from the head or pronotum. (Stag beetles are also fascinating, but they don't have horns.) less ↑
