Leptoglossus
leaf-footed bugs
Leptoglossus is a genus of true bugs in the leaf-footed bug family Coreidae, tribe Anisoscelini. Species are characterized by leaflike dilations of the hind tibia, a diagnostic trait of the genus. The genus is distributed throughout the Americas, with some introduced populations in Europe and Asia. Several species are economically significant agricultural pests, notably L. occidentalis, which has become invasive in multiple continents.

clypealis
western leaf-footed bug
Leptoglossus clypealis, commonly known as the western leaf-footed bug, is a phytophagous true bug native to western North America. Adults measure 18–19 mm in length and are characterized by brown coloration with leaf-like expansions on the hind tibiae and a pale band across the wings. The species has been documented as a pest of agricultural crops, particularly almonds and pistachios, causing kernel damage and fruit drop. Its range has expanded eastward in recent decades, with genetic studies confirming populations in Texas represent native range extensions rather than recent introductions.
Leptoglossus zonatus
leaf-footed bug
Leptoglossus zonatus is a polyphagous leaf-footed bug native to the Americas, ranging from the southwestern United States through Central America to South America. Adults measure approximately 20 mm in length with gray coloration, a zigzagging whitish band across the dorsum, and two distinctive yellowish spots on the anterior pronotum that serve as the primary identifying characteristic. The species has emerged as a significant agricultural pest, particularly in California almonds and Gulf Coast satsuma mandarins, causing direct feeding damage and transmitting plant pathogens. Two genetically distinct strains occur in the Western Hemisphere, with low overall genetic diversity suggesting potential for further range expansion.
