About Thyas coronata (Fabricius, 1775)
This species has a scientific name of Thyas coronata (Fabricius, 1775). It has a wingspan of approximately 82–96 mm. Its head and thorax are pale reddish brown, and its abdomen is orange with black segments. Forewings are sprinkled with dark specks, and feature a short dark sub-basal line, an outwardly oblique, slightly sinuous antemedial line, and a small round greyish orbicular spot. The reniform spot is large and chocolate-colored, ringed with grey, or broken into grey or chocolate spots that are each ringed with grey. There is also a slightly inwardly-oblique postmedial line, and a pale sub-marginal line that bends slightly below the costa. Hindwings are orange, with broad medial and sub-marginal fuscous black bands that do not reach the inner margin. The sub-marginal line is widest towards the costa. The ventral side is orange. The costal and outer areas of both wings are dark speckled, with a slight reddish suffusion, and a black patch is visible near the outer angle of the forewing. Mature larvae are dull sienna brown, with longitudinal blackish brown stripes. They have a dorsal black spot on the eighth somite, paired black dorsal tubercles on the tenth and eleventh somites, and a lateral yellow-edged spot on the fifth somite. The larval ventral side is dark, and the head is striped with black. The larvae feed on species from the following genera: Combretum, Quisqualis (including Quisqualis indica), Terminalia (including Terminalia catappa), Litsea, Anamirta, Pinus, and Nephelium. This moth is considered a pest on oranges, lemons and other Citrus species.
