Any photos of caterpillars? Be interesting to know who’s mad enough to eat them. I have no idea how to deal with black fly.

I will go on a caterpillar hunt and try to get a photo, agreed it would be interesting.  Will I need a shotgun,  or hazmat suit, do you think?

I couldn't see any caterpillars,  maybe it was birds pecking the leaves for the black fly. I will keep an eye out.
