Feeding the Ants
Once they're on the forest floor (or in this case my yard) they need to locate another host plant, typically a sapling or risk starvation. Some can survive by eating last years leaves that haven't decomposed but this isn't as nutritious for them.
(There's also colonies of Lasius interjectus, and Ponera pennsylvanica too but I don't think they eat caterpillars too often. The Lasius colonies farm root aphids like there's no tomorrow, and the Ponera I expect to be predatory towards small mites and spring tails and such.)
