Head capsule is dark gray and sparse yellow powder is visible in some individuals, with yellowish adfrontal area, and labrum and basal antacoriae a pale yellow. The integumentary color of T1-A10 is mostly vivid yellow, transversely decorated with black, dotted stripes. In lateral view, T2 is the most swollen area dorsally. Legs T1-3 are speckled with black on the lateral regions, while prolegs A3-6 have a yellow ground color similar to the former. Caudal horn on middorsal A8 is black and strongly developed.

) at Fugong County, Yunnan, 1221 m, on 28.v.2023. After being brought back for indoor observations, it did not continue to feed on this plant or accept mulberry, and it ultimately starved to death. The caudal horn usually points to the posterosuperior side at rest, but it will swing back and forth (from anterior to posterior sides, with unstable frequency and speed) when frightened and crawling. After feeding ended, mature larvae always left their host plants to pupate in a cocoon. The larvae of HT and PTs span their cocoons ca. 05-09.v.2022.

The exterior shell is translucent after sclerotization is completed, showing yellowish tissues inside. Melanin is primarily pigmenting the spiracles A2-8 of the pupal exuviae, then distributed internally around the spiracle T1, and also the areas of middorsal A1-7 and dorsolateral T1-3. The subterminal costal margins of forewings come in contact medioventrally; antennae, maxillae and legs T1-3 are clearly visible.

During development of the adult in the pupa, the proximal regions of antennae, of the lateral areas of compound eyes, off the tarsi of legs T1 and of the tip of A10 become pigmented blackish earlier than other structures.

White ellipsoid in general, about twice as long as wide, with the pupa nested inside along its longitudinal axis. The outer fibers form a wrinkled, irregular layer, that appears as a loose and perforated filament-layer in horizontal section. The innermost [pupal chamber] surface of the cocoon is regular and relatively smooth.

Head largely covered by black scales, but the frontoclypeal area is off-white, with black compound eyes and bipectinate antennae. The labial palpus is but vestigial and very minute. The white scales are distributed on the subdorsal areas T2-A8, the subventral areas A2-8 and the tip of A9. The abdominal venter is grayish, while other areas of the whole body bear black scales; especially on T1 and tegulae, these scales are longish and hair-like. Legs T1-3 are also darkly colored, and the longest hair-like scales are located on the lateral margins of tibiae and basitarsi of forelegs. Both fore- and hindwings are semitransparent, the lengths are ca. 2.2 cm (from the wing base to the tip of R4, HT) and ca. 1.8 cm, (from the wing base to the tip of CuA1, HT), respectively. Viewed from both dorsal and ventral sides, each wing-vein is located within a gray-black scaly stripe, such bands likewise decorated on the postbasal (only forewings), median (all wings), marginal (all wings, and here including costa-apex-termen-inners) areas, while other regions have a light cover with white scales. The termen of the hindwing is slightly concave around the tip of 1A.

Amongst the genital structures, tegumen and vinculum are fused and form a narrowly elliptic ring, with the vinculum extending into a very short saccus. The uncus is deeply bilobed, laterally sclerotized and medially membranous, its wedge-shaped terminal is inferolaterally setose. A pair of cambered sclerites derived from the gnathos is strongly developed, linked with the uncus by lateral membrane. The narrow and crescent valva is expanding terminally which ended with a rounded and smooth dorsodistal margin, each cucullus has serrated inferior margin with two or three identifiable pointed teeth bearing medioventral corona. The juxta is V-shaped and slightly protruding. The phallus is thin, long and straight, with a pointed tip that has a slightly helical opening; the caecum penis is well developed.</paragraph>

Color pattern is nearly identical to males,but females are usually larger in size than males. Visually, wings appear narrower, longer and paler than in males, with lengths of forewing ca. 2.4 cm (from the wing base to the tip of R4, PT [A23072706]) and hindwing ca. 1.9 cm, (from the wing base to the tip of CuA1, PT [A23072706]). Prior to oviposition, A2-7 medioventrally covered by many long, black scales.

Adults HT and PTs emerged from cocoons between 14 and 18.v.2022. In resting position, moths usually hold their forewings with their costal margins horizontal (perpendicular to the body), while the anal angles of the hindwings are widely separated from each other (Fig.

). There was no successful pairing in captivity, but adults were found to be active during the day. Unfertile females nonetheless laid eggs, covering them with black scales from their abdominal midventral areas. It is noteworthy that the dorsal epicuticle of the membranous areas of wings appeared slightly iridescent while moths were alive, which was difficult to observe in dead, dry specimens.
