Havingfound a sheltered corner of a fence, or some similar situa-tion, it proceeds to spin a silken web upon the under sideof the chosen board, in which a little later it entanglesitshind feet and hangs downward preparatory to becominga chrysalis. The bare outline that I have thus givenwould apply to many species of butterfhes. Among.
