American Chestnut Ermine Moth (Argyresthia castaneella)  

The American Chestnut Ermine Moth, which is known from New Hampshire and Vermont was described in the year 1915, since that year no trace of this species could be found again.  

The larvae of this species fed on the bark of the American Chestnut (Castanea dentata (Marsh.) Borkh.), a tree species, which is nearly extinct now, and of which today almost only small sprouts exist, of which only very few get large enough to produce sufficient quantities of bark.
