The wingspan is 12–20 mm. There are about three overlapping generations per year and a partial fourth.
The larvae attack various drying and dried fruits, fallen figs and damaged or moldy clusters of grapes on vines. Raisins are attacked until they become too dry. Other recorded food includes cottonseed cake, cacao beans, cashew kernels and fallen mulberries. Larvae are white with four rows of purple spots along the back. Full-grown larvae are about 10 mm long.
