Butterfly

The caterpillars of some of these insects are very injurious to the gardener, though those of the moth are still more numerous and destructive. The butterflies which are the chief causes of mischief. in our gardens are Pontia brassica, P. rapa, P. napi, and Pieris crategi. The smells of coal tar and of gas lime are particularly offensive both to butterflies and moths, and those may be readily strewed about the plants liable to become the depositories of their eggs. If shreds of flannel are placed in the branches of gooseberries, or among cabbages, etc, the parent insects are said to place their eggs there in preference to the leaves.
