In open, rocky places, moist or dry, the CLAMMY EVERLASTING, SWEET BALSAM, OR WINGED CUDWEED (Gnaphalium decurrens) prefers to dwell. A wholesome fragrance, usually mingled with that of sweet fern, pervades its neighborhood. Its yellowish-white little flower-heads clustered at the top of an erect stem, and its pale sage-green leaves, densely woolly beneath, the lower ones seeming to run along the stem, need no further description: every one knows the common everlasting. Its right to the Greek generic name, meaning a lock of wool, no one will dispute. From Pennsylvania and Arizona, north to Nova Scotia and British Columbia, its amaranthine flowers are displayed from July to September, the staminate and the pistillate heads on distinct plants. Many insect visitors approach the flowers; some, like the bees, are working for them in transferring pollen; others, like the ants, which are trying to steal nectar, usually getting killed on the sticky, cottony stem; and, hovering near, ever conspicuous among the larger visitors, is the beautiful hunter's butterfly (Pyrameis huntera), to be distinguished from its sister the painted lady, always seen about thistles, by the two large eye-like spots on the under side of the hind wings. What are these butterflies doing about their chosen plants? Certainly the minute florets of the everlasting offer no great inducements to a creature that lives only on nectar. But that cocoon, compactly woven with silk and petals, which hangs from the stem, tells the story of the hunter's butterfly's presence. A brownish-drab chrysalis, or a slate-colored and black-banded little caterpillar with tufts of hairs on its back, and pretty red and white dots on the dark stripes, shows our butterfly in the earlier stages of its existence, when the everlastings form its staple diet.
