About Syntomoides imaon (Cramer, 1780)
This moth species has a wingspan of 34 millimeters. Its frons and collar are yellow, and the metathorax has a yellow streak. The first abdominal segment bears a yellow band, which is sometimes indistinct and obsolescent. The forewing features large hyaline patches: one fills the cell, another fills nearly the entire interno-median interspace, one sits at the junction of veins 2 and 3, there are two subapical patches, and two submarginal patches. In the subspecies S. i. sargania, a long streak is present between veins 5 and 6. In other forms of the species, this streak is reduced to a spot, or may be absent entirely. The hindwing has a postbasal hyaline patch that barely extends (or does not extend at all) beyond the cell. The tips of the antennae and the proximal joints of the tarsi are white. The size of the forewing spots varies considerably between individuals. Males are more slender, and have a longer abdomen than females.
