Photo by Drees. Although capable of flight at certain times of the year, adults collected from host plants rarely fly. Eggs hatch in about 7 days. Adult weevils emerge from the pupae in about 7 days. Several generations occur annually.
Mouthparts are for chewing.
They have also been reported to feed on Cassia and Xanthoxylum species. Larvae feed on the nitrogen-fixing root nodules of these legumes. This beetle is easy to locate on stems and leaves of Sesbania weeds. They can be kept alive for relatively long periods and will not bite when handled. Immature stages must be collected from the roots of the host plants by sifting through the soil.
