When the eggs hatch, the emerged larvae will bury into the soil and feed on the root nodules, creating an inability for the plant to fix nitrogen. It feeds and develops in several species of Solanaceae but is better known as a pest of peppers, Capsicum spp.

Identification of some genera of weevils is possible through the use of the Biologia Centrali-Americana (Sharp and Champion 1911, Champion 1903, 1910) and by using keys for the United States of America and Canada (Kissinger 1964, Anderson 2002); however, material in the Biologia Centrali-Americana is notably outdated, keys are not always presented, and the North American keys do not include a significant portion of the Mexico and Central American genera, moreover, the taxonomic status of some genera has changed and new genera have been described and recorded for the region. 58
