The form prevailing in each family is substantially the same; each species seems to turVa- ' steadily to one characteristic form; but there are riations. °'® marked variations in the habit of certain species, as in the Insular spider, whose nest architecture we have seen is not constant in form among the individuals of that species. Indeed, the variation extends without a doubt to the habits of the same individual under different circumstances. This opens a most inter- esting feature in the story of spider industry, which may as well be kept in mind as we proceed with the description of these nesting habits. It will be fi«- 262. Nest of strix within obvious that some of the variations are adaptations ''''' ''â to changed environment. Some of the most decided of these variations have been observed in the nest architecture of Epeira strix. I observed two of this species domiciled in the beautiful hedgerows of a New England meadow, within nests of several rolled leaves, which had an inside lining quite like that which is made by Insularis. Both nests were below the orb, one ten inches below. The second example had for her nest a very bright red rolled leaf with a tube inside of it, which made a strikingly pretty object. The ordinary nest of Strix when domiciled in the open field or wood is a rolled leaf. A single leaf is taken, the edge pulled up, drawn under, and fastened by adhesive threads into a rude cylinder, within Varia- which the spider hides during the daytime. (Fig. 262.)
