Platyphora
Platyphora is a genus of broad-shouldered leaf beetles belonging to the Chrysomelidae family.
These tropical insects usually have bright warning coloration ( aposematism) and a chemical protection against predators. The toxins are secondary metabolites collected from the host plants they eat, mainly Boraginaceae, Asteraceae, Asclepiadaceae, Convolvulaceae, Solanaceae and Apocynaceae.
