• Leptoglossus 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.

• Recurvaria

  Recurvaria is a genus of small moths in the family Gelechiidae, established by Haworth in 1828. The genus contains approximately 40 described species distributed across the Holarctic region. Several species are economically significant as pests of coniferous trees and pistachio, with larvae that mine needles or feed internally within fruits. The genus exhibits diverse life history strategies, including univoltine and bivoltine cycles, with some species requiring two years to complete development.
