The butterfly's population is likely declining, although information gaps preclude us from quantifying its population trends. The species is believed to be extirpated from six of 16 locations that it has been known to inhabit, and it is only "presumed" to occupy eight of the 10 other locations. In other words, it may exist in 10 relatively confined locations throughout the mountains, but for eight of those locations it probably has only a tentative existence, at best.
