The larvae are a pest of the flowers of Prosopis chilensis and Acacia farnesiana in Hawaii.

Usually a light brown spot develops on the external surface of the bud at the site of oviposition.

The larvae has a brown head and the remainder of the body is white to pale yellow.

Often as many as 15 florets are joined together in a row, forming a tunnel in which a fully grown larva may be found.

The pupa is almost white at first, turning brown soon after, and almost black when the adult is ready to emerge.
