โฆ Synopsis
Towards the end of September I received, through the kindness of Mr. Jacob Doll, of Brooklyn, N. Y., a considerable number of caterpillars of Junonia ccenia Hiibner which had been found near Brooklyn in a portion of Long Island that is rather damp and overgrown with bushes and low plants. Here the butterflies had been rather abundant one or two months previously. Mr Doll assures me that the frequency of J. cenia in this region is not at all the rule. Although the butterflies are never completely absent in any year, there are usually only a few caterpillars to be found. J. caenia in the northern states belongs, therefore, to the category of butterflies that appear in great numbers only during certain years. It is, moreover, probable that the abundance of this form is due to migration from the south, and that this migration to the north would be the stronger the dryer and hotter the season.
