The gray emperor resembles the tawny emperor quite closely, except that it is smaller and 5 3 Plate XXIX. 0000 6 4 duller in color and more slender and graceful in shape. It is a long-lived butterfly and may be found during the entire season. The caterpillar is similar in habit to that of the goatweed emperor. It lines the upper surface of the leaf with silk, causing it to roll up, making a more or less secure nest.

The gray emperor is partially double-brooded.

Some of the caterpillars of the first brood finish their growth in a great hurry and change to adults, while others of the same brood dawdle along and hibernate. The species extends from southern Pennsylvania, Ohio, and Illinois southward. Lastly his shinie wings as silver bright, Painted with thousand colors passing farre All painters' skill, he did about him dight:

Not halfe so manie sundrie colours arre In iris bowe; ne heaven doth shine so bright, Distinguished with manie a twinckling starre ; Nor Junoes bird, in her ey-spotted traine, So many goodly colours doth containe.
