I received, 25th June, from Mr. C. P. Whitney, New Milford, N. H.,a cluster of about 50 eggs of this species, laid on the under side of a leaf of Diplopappus umbellatus, date of deposition not stated. The larvæ hatched 28th June. The food plant not being obtainable by me, I gave them leaves of Chelone glabra, on which phaeton feeds, but so long as the least bit of the dry leaf of Diplopappus on which they hatched remained, the larvæ declined the Chelone, and then after starving many hours they attacked it vigorously. But, meantime, for want of proper food, several died.
