The moth seems to have been noted in each month from April to August, but it is most frequent in May and June. {284} BORDERED BEAUTY (_Epione apiciaria_). The orange-yellow moth whose portrait is shown on Plate 119 (Fig. 1) has the outer margins, beyond the second blackish line, more or less shaded with purplish grey, inclining to purple near the line; on the fore wings, the first cross line is angled at the middle, and the second line runs to the tips of the wings. Gynandrous specimens of this and also the following species have been noted. The early stages are figured on Plate 121, Figs. 2, 2a. The eggs, which are laid in July and August on the food plant, are pale yellow at first, then reddish, with white dots and patches. The caterpillars generally emerge in the following spring, but sometimes, at least in captivity, they hatch in about a fortnight, feed up quickly, and attain the moth state in September or October. Caterpillar, brown, with a greenish or ochreous tinge; along the back of rings 3 to 6 is an ochreous patch, and within this a black mark, and on the rings following 6 there are more or less distinct ochreous diamonds; a dull yellowish line low down along the sides; head, dull reddish brown. It feeds, in May and June, on willow, sallow, alder, etc. The moth is out in July and August, and is not uncommon in many parts of Southern and Eastern England. Its range extends through England, Wales, and Scotland to Sutherland. In Ireland, it is widely distributed, and not at all scarce in some northern localities. DARK BORDERED BEAUTY (_Epione parallelaria_). As will be seen on referring to Plate 119 the sexes of this species are strikingly different. The male (Fig. 2) is very similar to the last species, except that the first cross line is curved and reddish brown in colour; the second line runs to the front margin before the tip, and the outer margin beyond is almost entirely purple. The female (Fig. 3) has the ground colour pale yellowish, and the outer borders narrowed, especially on the fore wings. Very occasionally, the ground colour in the male approaches that of the female. The eggs (Plate 121, Fig. 1) are pale yellow when deposited, but afterwards become honey yellow, freckled with reddish, and later they are red all over. The caterpillar is dingy brown, inclining to greyish on the back of the first four rings, a dark mark about the middle of the back, and on each side of this two slender whitish lines are fairly distinct; underside, whitish tinged with pale violet. It feeds, in May and June, sometimes later, on dwarf sallow and willow, birch, aspen, etc. [Illustration] 2 Pl. 118. 1. SWALLOW-TAILED: _caterpillar_. 2. ORANGE MOTH: _caterpillar_.
