I recently discovered the AntsCanada YouTube channel. This guy makes amazing terrariums for growing ant colonies (and sometimes other species), and has some very informative videos with high quality macro videography. I have learned a lot about ants watching his videos these past few days.

This particular video might be valuable to people into mycology too. Several animal species are known to farm fungi, but this is the only instance I know of this process being documented in video in such detail.
