Cydnidae
| Description | Cydnidae are a family of shield bugs, known by common names including burrowing bugs or burrower bugs. In some older classifications, Cydnidae, sensu lato includes the subfamily Thyreocorinae (now part of the "Corimelaenidae"), which are known commonly as negro bugs (early name to be avoided), or ebony bugs, and/or the families Thaumastellidae and Parastrachiidae. 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.
