State Ranking Justification [-]
Although this species seems to have expanded its range, it nevertheless is always found in very low numbers and has been found at only a few locations confined to extreme southeastern New York. Population abundance is known to vary widely from year to year. Because it appears to be a generalist, occupying heavily urbanized areas and feeding on a variety of common food sources in both the adult and caterpillar stage, threats to the viability of populations are unclear at this time. It is not certain that this species will remain on the active tracking list in the future.
