Elementary studies in insect life Elementary studies in insect life elementarystudie00hunt Year: 1902 OUR FRIENDS AND FOES 151 sired location. As the larva grows it finds it necessary to enlarge its case both in length and circumference. The wav it does this is rather interesting. Without <u bursting its case the larva makes a slit half-way down one side, and inserts a triangular gore of new material. FIG. 120. Larvre of clothes moth feeding on felt. Photographed from life. A similar insertion is made on the opposite side. The larva revolves itself without leaving the case, and makes corresponding slits and additions in the other half. It lengthens its case by adding to either end. In appearances the case looks like a matted mass of wool. If the interior be examined it will be found to be lined with soft white silk. If the larva is trans- ferred from time to time to fabrics of different colors, the cases .may be made to assume as varied a pattern as one desires. The varied colors will illustrate the peculiar methods of enlarging just described. The fully developed larva about to pupate attaches itself by silken threads to the garment upon which it has been feeding. t>>
