Common Name(s): Burrowing Bug
Adults are black, roughly 1/4 inch long, and superficially resemble small stink bugs. However, they are more oval and have spines on their leg segments (tibiae). The front wings are clear and membranous (hemelytron) at the tips beyond a black thickened basal part (corium and clavus), and can be seen at the rear end of the body when the wings are held at rest.
Members of the Thyreocoridae, e.g. Corimelaena pulicaria (Germar) (Hemiptera: Thyreocoridae), are similar to burrowing bugs. However, when at rest, adults lack clear membranous front wing tips because the wings are completely covered by an enlarged shell-like plate (the scutellum, which is normally a small triangular-shaped area between the basal part of the wings just behind the pronotum or shield located just behind the head). They are very beetle-like in appearance because the membranous wings are not easily visible. They are black or with a paler margin along the pronotum and scutellum. These bugs feed on grasses, weeds, berries and flowers. Scutellaridae have a similar shell-like plate on the back. They are generally brown to green and often enter homes in the fall.
Habitat & Hosts
Burrower bugs feed on parts of plants including pepper and spinach seedlings, vegetable crops, cotton and peanuts. Burrowing bugs occur in high numbers around lights at night during periods in the fall. Can be a pest of crop production; large numbers of adults encountered around lights at night; found throughout Texas; medically harmless.
In Texas, burrowing bugs overwinter by burrowing into the soil at a depth of 6 to 8 inches below the surface until the first week of March, at which time they moved up to the surface.
