The seed beetles resemble very much to the weevils, but are distinguishable from them by their antennas which do not have their first article very lengthened and are not bent, and by their rostrum much shorter. The Bruchinae subfamily is part of the Chrysomelidae.
The larvae eat seeds of many plants, and some are very harmful to the stored food products. The adults are common on the flowers and the foliage. Some jump, or pretend to be died when they are disturbed (thanatosis).
