  • Hippodamia convergens (Coleoptera: Coccinellidae), is a common lady beetle species in the New World. Although H. convergens larvae and adults are polyphagous, they prey primarily on aphids, including cotton, pea, melon, cabbage, potato, green peach, and corn leaf aphids. As an effective biological control agent, H. convergens can reduce aphid densities in greenhouses. When aphids are limited, however, H. convergens feeds on thrips, small insect larvae and eggs, mites, and honeydew secreted by aphids and other sap-sucking insects, as well as plant based foods, such as pollen, nectar, and petals. Nevertheless, convergent lady beetles must consume preys to reproduce.[1][2].
