The larva feeds on an annual {Crolon cupi-tutum) which is tolerably common iu Illinois,Missouri, Kentucky, and westward, where itis known by the name of (ioat-Weed.

This roll of the leaf [Fig. 82.]. —Coppery-red and h is generally quite uniform, and is made in thefollowing manner: Extending itself on the mid-vein, with its head towards the base of the leaf,the larva attaches a thread to the edge, at aboutone-fourth the distance from the base to thepoint. By a tension on this thread, it draws thisedge partly toward the opposite one, and fastensit there, being assisted in the operation by thenatural tendency of the leaf to curl its edgesinwards. Fastening a thread here, it repeatsthe operation until the edges meet, and then itproceeds to firmly join them nearly to the apex,leaving a small aperture through which to passthe excrement. During hot days the larvaremains concealed in the leaf, and towardsevening comes out to feed, though sometimesit feeds upon its house, eating the leaf down halfway from base to point. It then abandons itand rolls up a new one. In the breeding cage,when placed in a cool shady room, the larvaseldom rolls up
