There is a published study asserting there are four distinct ecotypes = subspecies of Eastern Arogos (arogos arogos) based on both phenology and different larval food plants: Gulf coast, peninsular Florida, Georgia to southern New Jersey, and northern New Jersey. If this is true, it would be better to use (if possible) the southern New Jersey population for any attempt to restore in NC. This is all summarized on the NatureServe species write up.

FL also is part of the Eastern Arogos range.
Atrytone arogos arogos -- NJ to FL, west to LA (Butterflies of America);
Atrytone arogos iowa -- IL, IA, MN, ND, SD, MT, WY, CO, NE, KS, MO, AR, OK, TX (Butterflies of America).

There are many more and larger populations in FL, than in NJ, where I assume they are almost on their deathbed there. I doubt the NJ populations should be used for any re-population efforts outside that state. FL -- maybe so.

Yes, we didn't lose our last population owing to loss of habitat. The habitat at Croatan is still there. It just lost its bugs owing to losing all individuals -- in larval or pupal stage at the time of the fire. Thus, the species should be able to survive there -- if properly managed by fire of only parts of the savanna in any single year.

I was fortunate to see several Arogos Skippers in NC at the Croatan National Forest site before that population disappeared ten years ago. Nearly twenty years ago experts did regional surveys and an assessment of the eastern population of Arogos and concluded it was rare, declining, and had disappeared from numerous sites. This was the opportunity for the Fish & Wildlife Service to listing and protect remaining populations under the federal Endangered Species Act. This would have provided protection from collecting, more attention from federal land management agencies, development of a plan to recover the species, and opportunity for funding for conservation. Unfortunately, the Fish & Wildlife Service failed to act.

As Harry mentioned, the Forest Service fried the only known population of Arogos in NC and despite attention by people in the field and searching favorable looking habitat, it may be extirpated in NC. No known populations exist now between New Jersey and Florida.

I understand the NC Arogos are/were the same as those still around but rare in southern New Jersey. Some researchers think this is one of four ecotypes and possibly distinct subspecies of eastern Arogos. The Forest Service and FWS could maybe atone for their past actions and inactions by investigating and if feasible developing a plan to use the New Jersey population to reestablish a population at the previous NC site. We know prior to the excessive burning this site supported a population. Reestablishing this population would provide more resiliency for the species. There is innovative and successful work going on, including captive rearing, to expand the endangered St Francis Mitchell's Satyr on Fort Bragg. Similar efforts should be used for the disappearing eastern Arogos before it is too late.
