The other I found in our garden, this time feeding on vervet monkey scat.
I don't know whether scat feeding is a male habit, or what purpose it serves the animal. It is well described in male Charaxes.
Steve Woodhall also mentions that the males also mark territory with scent hairs on their posterior abdomen. Is this one scent marking?
Food plants cover a wide range, and include our very invasive Bugweed (Solanum mauritianum.)
I have added the individual feeding on monkey scat.
