I have watched them closely and can see no reason for their being ; A week later she wrote again : " It seems this morning as if almost every larva was attended by a ' harvester,' which apparently stroked it with a leg or two or merely stood near or over it. Sometimes the touch made the larva curl up, but more often it seemed to have no effect. It is very curious, and I watch and watch but can learn ; The species concerned seemed to be the common Striped Harvest-spider,* as I judged from some half- grown specimens sent by Miss Soule. As to the reason for their presence I can only conjecture that they found food in connection with the caterpillars in some way. Toads were seen to devour many of the caterpillars, although of course these creatures are comparatively so rare that they could make lit- tle impression upon the pests. Birds, however, did a great deal toward reduc- ing the numbers of the insects. Miss Soule ob- served robins, orioles, chipping sparrows (Fig. 32), cat birds, cuckoos, the red-eyed, white-eyed, Fig. 31. The Chickadee. * Litbiimiin Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original New Hampshire Agricultural Experiment Station.
