Palpita flegia
Cramer, 1777
satin white moth, Satin White Palpita
Palpita flegia is a crambid commonly known as the satin white moth. It was described by Cramer in 1777 and has a broad distribution across the Neotropics and into the southern United States. The is a documented pest of ornamental plants in the Apocynaceae, particularly Cascabela thevetia. Laboratory studies have established detailed parameters including six larval instars and specific thermal requirements for development.
