Royal Poinciana Moth
Melipotis acontioides, commonly known as the Royal Poinciana , is a moth in the Erebidae. The was first described by Achille Guenée in 1852. It has a broad distribution spanning the southern United States, Mexico, Central and South America, and the Caribbean, with a distinct to the Galápagos Islands. The larvae are specialized feeders on certain leguminous trees.

The can be distinguished from similar Melipotis species by geographic range and association with plants. The Galápagos M. a. producta was described by Hayes in 1975 based on insular . Accurate identification to species level typically requires examination of genitalic characters or molecular analysis.

Appearance
have a wingspan of approximately 43 mm. As a member of the Melipotis, it exhibits the typical forewing patterning of the group, though specific coloration details are not well documented in available sources.
Habitat
Found in diverse environments across its broad range, including arid and semi-arid regions of the southwestern United States, tropical and subtropical forests in Central and South America, and insular in the Caribbean and Galápagos. Associated with areas where plants of the Delonix and Parkinsonia occur.
Distribution
Native range extends from the southern United States (California, Arizona, New Mexico, Texas, Florida) through Mexico and Central America to Brazil, Argentina, and the Galápagos Islands. Also present throughout the Caribbean including Cuba, the British Virgin Islands, Jamaica, and Puerto Rico.
Diet
Larvae feed nocturnally on Delonix regia (Royal Poinciana) and of Parkinsonia including P. and P. florida. feeding habits are not documented.
