The larvae of Edwards' Haristreak and some related butterflies are defended by ants who eat sweet secretions from them. The ants that tend Edwards' Haristreak caterpillars make special shelters for them at the bases of the small oaks they ascend to feed on at night.

This is a very localized species, but apparently there are dozens of occurrences in southeastern New York. The species still occurs in the Albany Pine Bush and there have been isolated occurrences in Oneida, Steuben, and Delaware Counties. Some habitats are management dependent. The species at present is not imperiled, but does occur within a limited range and specialized habitat.
Short-term trends indicate a stable to declining (10% to 30%) population.
Long-term trends indicate a moderate to substantial decline (25% to 75%) of the population, due to the loss of historical pine barrens.
