 Though similar in appearance to a beetle at casual glance, they can be distinguished by both their piercing/sucking mouthparts, and wing configuration (beetle elytra are split directly down the back of the insect).Of some 750 species of burrower bugs, 27 are reported as crop pests, and six species are thought to feed on peanut.In Goiás (Brazil) the flocks are observed in the rainy season, November to March, which coincide with the period in which adults of these insects are found in the soil.
