Ambragaeana stellata (Walker, 1858)

Once known as Gaeana stellatayes, its name has changedAmbragaeana stellata (Walker, 1858) can be found in China, Thailand, India, and likey other nations the south-eastern part of Asia. Ambragaeana cicadas belong to a group nicknamed the “butterfly cicadas” because of the butterfly-like colors and patterns of their wings.

“Stellata”, I believe, is derived from the Latin word for “star” — it doesn’t take much imagination to see the “stars” in the wings of this cicada.

Scientific classification:
Family: Cicadidae
SubFamily: Cicadinae
Tribe: Gaeanini
SubTribe: Gaeanina
Genera: Ambragaeana
Species: Ambragaeana stellata (Walker, 1858)

Ambragaeana stellata stellata (Walker, 1858)
The image says Gaeana stellata, but the newest name for this cicada is Ambragaeana stellata.

Worth noting: There are two sub-species of Ambragaeana.
