Spartocera diffusa
(Say, 1832)
leaf-footed bug
Spartocera diffusa is a leaf-footed bug in the Coreidae, characterized by the expanded, leaf-like hind tibiae typical of this group. It is native to North America and the Caribbean, with records from the southeastern United States (Florida, Georgia, Texas) and the Windward Islands. The species was originally described by Thomas Say in 1832. Like other coreids, it is a plant-feeding true with .

Identification
Distinguished from other Coreidae by specific features of the expanded hind tibiae and overall body proportions. The Spartocera contains multiple that require careful examination of tibial expansion patterns, body size, and coloration for accurate identification. S. diffusa specifically can be separated from by the degree and shape of tibial dilation and geographic distribution. Specimen examination against described type material or use of regional keys is recommended for definitive identification.
Appearance
Medium to large-sized true with elongated body form. Hind tibiae expanded and flattened, giving the characteristic 'leaf-footed' appearance. long and slender, typically with four segments. Body coloration varies but often includes brown, reddish-brown, or gray tones with possible patterning. Scutellum triangular. Forewings () with leathery basal portion and membranous portion, typical of Hemiptera.
Habitat
Associated with woody vegetation and forested areas. Specific plant associations are not well documented in available sources, but coreid typically feed on seeds, fruits, and vegetative parts of plants.
Distribution
Southeastern United States: Florida, Georgia, Texas, New Mexico; Caribbean: Windward Islands. The disjunct distribution between mainland North America and Caribbean islands suggests possible human-mediated transport or historical biogeographic patterns.
Seasonality
Activity patterns not specifically documented. As a temperate to subtropical , likely active during warmer months when plants are available.
