Black caterpillars with white side spots, 2 orange spots on back & sandy/orange tufts, hatching in a silk tent.
No interactions present.
Yes, looks like Brown-tail. As you probably know, the hairs on these caterpillars can cause severe irritation and skin reactions in some people, so avoid any close contact with them.

Watch clusters of brown-tail larvae for tachinid flies that might be observed laying their eggs on or around the moth larvae. Brown-tail has a few quite rare parasitoids associated with it, like Townsendiellomyia nidicola and Carcelia laxifrons :)
Thanks for the advice Martin!
