. Elementary entomology. Insects. 2O6 ELEMENTARY ENTOMOLOGY branches with strands of silk and in them spin little silken cells, the whole forming a strong web, within which they pass the winter and emerge to complete their growth in the spring.

On the from side and back. (Natural size) side of each segment is a characteristic white dash, and the little red spots characteristic of this family are found on the center of the sixth and seventh abdom- inal segments. The tubercles along the back and sides are thickly covered with short brown hairs, the masses having a velvety appearance. These are the nettling hairs, which, when they alight on the skin, produce an eruption very similar to that caused by poison ivy, and which is so painful and annoying that, where the cater- pillars become abundant, they render life miserable for the inhabitants dur- ing early summer. As the nests of this pest have been imported on pear seedlings by nurserymen in almost every state during the past two years, it will be remarkable if it is not soon found outside of New England, and should be constantly watched for, so that it may be brought under control at once before it spreads. This family is a small one, and has almost no species . . FIG. 325. Winter web of the of economic importance in this country brown-tail-moth caterpillars other than those mentioned. (Reduced).
