Chalcodermus serripes
mimosa green-seed weevil
Chalcodermus serripes is a true weevil in the family Curculionidae, commonly known as the mimosa green-seed weevil. It has been investigated as a potential biological control agent for the invasive plant Mimosa pigra. The species is native to North America. Its common name reflects its association with Mimosa seeds.
Coelocephalapion aculeatum
Coelocephalapion aculeatum is a flower-feeding weevil in the family Brentidae (formerly Apionidae) that specializes on the invasive weed Mimosa pigra. Females exhibit selective oviposition behavior based on host inflorescence developmental stage and conspecific damage levels. Larval development occurs entirely within host flowers, with survival rates varying significantly according to inflorescence maturity. The species has been investigated as a potential biological control agent for M. pigra in regions where this plant is invasive.
