The caterpillars, too,of the Skipper Butterflies spin a slight cocoon, asa rule drawing together a few of the leaves of theplant upon which they feed. The caterpillars of some moths as soon as theyleave the egg combine to weave an extensive sheetof silk around the twigs of their food-plant, enclosinga considerable number of leaves upon which theycan feed in safety. A very familiar example of thisclass of spinner is the little grey moth Hypono-m
