Many spidersthat live habitually on treetrunks resemble bits of bark orsmall, irregular masses of whole family of spiders, whichlive in flower cups lying in waitfor insects, are white and pinkand particolored, resembling themarkings of the special flowersfrequented by them. This is, ofcourse, a special resemblance notso much for protection as for ag-gression; the insects coming tovisit the flowers are unable todistinguish the spiders and fallan easy prey to them. Any field student of insects, by paying attention to the matter of special protective resem-blance, c?n soon make up a striking list of examples. Someof these may be more convincing to him than to persons see-ing his specimensin the collectingboxes, and someindeed will prob-ably be ques-tioned by closetnaturalists. Butnevertheless nocollector or field FIG- 259.—A pipefish. Phyllopteryx, which resembles the sea- n a weed among which it lives. failed to note.
