Spot-sided Coreid
Hypselonotus punctiventris, commonly known as the Spot-sided Coreid, is a leaf-footed bug in the Coreidae. are notable for their striking color pattern, including a bright red patch on the surface of the visible when wings are open. The is found in the southwestern United States, Mexico, and Central America, where adults feed on a variety of flowering plants. Despite its abundance in some areas, it is rarely considered a pest of agriculture or gardens.

Identification
Distinguished from similar coreid by the combination of its bold color pattern and the bright red abdominal patch revealed when wings are opened. Young nymphs can be recognized by their disproportionately large, thickened compared to other instars. The lacks the leaf-like expansions on the hind legs found in many other Coreidae .

Appearance
average approximately 13 millimeters in body length. The body displays a bold, conspicuous color pattern. When wings are opened, a bright red patch is visible on the surface of the . Young nymphs possess oversized, thickened and lack the wings present in adults. Final instar nymphs have wing pads that will develop into functional wings in the adult stage.
Habitat
Associated with flowering plants and shrubs. In Texas, frequently found on Yellow Trumpetbush (Tecoma stans) and Frostweed (Verbesina virginica). Occurs in landscaped areas with trees and shrubs as well as natural vegetation.
Distribution
United States (Arizona, Texas, with a single record from Arkansas), Mexico, Belize, and Guatemala.
Seasonality
are commonly observed in late October and early November in central Texas; activity period likely extends through warmer months in southern parts of range.
Diet
feed on a variety of flowering plants. Documented plants include Rio Grande Abutilon (Abutilon hypoleucum) and other members of the mallow (Malvaceae).

Life Cycle
Develops through and nymphal stages to adulthood. Nymphs lack wings and possess distinctive thickened . Final instar nymphs have wing pads that become fully functional wings in . Specific details of egg stage and number of instars have not been documented.
Behavior
can fly well. When disturbed, may open wings to reveal the bright red abdominal patch, possibly as a startle display. Nymphs and adults are found on flowering plants, suggesting active foraging for floral resources.
Ecological Role
Feeds on flowering plants as ; specific role in pollination or plant damage has not been quantified. Not considered a significant agricultural pest.
Human Relevance
Not a pest of agriculture or gardens. Valued by entomologists and naturalists for its striking appearance. Observations of this may contribute new distributional and biological information due to limited formal study.

Taxonomic notes
The Hypselonotus exhibits considerable color variation among and within , making field identification challenging without examination of specific morphological characters.
Research opportunities
The is considered understudied; nearly any biological observation may represent new information. A 2008 record from Arkansas extended the known U.S. range eastward from Arizona and Texas.
