This butterfly appeared earlier than usual with us last year. It is not seen on the wing sooner than the 10th or 12th of June, but this season they were tolerably common as early as the 1st, and probably had been then flying for several days. The delight in the sunny openings found oftimes in partially cleared woods, also in wooded lanes and roads and the sunny edges of the forest, where by their peculiar jumping flight they may be readily recognized, sometimes singly, at other times sporting in twos and threes. For the first few days the specimens capturad will be found to be nearly all the male sex, but after this the females begin to appear and both sexes are found together during the remainder of their short season of life which does not usually extend beyond the first week in July.
