Earlier this week I was sweeping some debris off our footbridge to discover a very large infestation of black caterpillars on a ficus tree nearby. I don't remember ever having seen this variety of caterpillars, anywhere. Except for the orange head, they are totally black and quite large. I didn't take time to count them but there must have been hundreds of them aggregated together on the lower part of the ficus trunk. I'll be going back to do an update of them tomorrow morning.
