Nothing has been known of the history or earlier stages of this butterfly till quite recently, except what Boisduval and LeConte (1833) gave, both plate and text having been copied from Abbot (about 1800). On the plate the mature larva is represented as lying on a leaf of Hawthorn, and the chrysalis is attached to a stem of same. The larva is green and white-striped, and neither in coloration nor shape resembles the real larva, and the description in the text is made up from the figure. The chrysalis is a little better. The larva (according to Abbot) “lives upon Cratægus, and the species is very scarce.” We also read that “this butterfly is plainly quite unlike the true Polyommati in its caterpillar and the shape of its chrysalis. Godart, who knew this species only by the description of Fabricius, wrongly believed that it was an Erycina.” Boisduval puts it in Polyommatus with Phleas.
