• Blepharidopterus angulatus

  black-kneed capsid

  Blepharidopterus angulatus is a predatory mirid bug native to the Palearctic region, with established populations in North America. It serves as a generalist predator of mites, aphids, and other soft-bodied arthropods on deciduous trees and shrubs. The species has been studied extensively for its potential as a biological control agent in orchards and its complex ecological relationships with parasitoids.

• Velarifictorus micado

  Japanese Burrowing Cricket

  Velarifictorus micado, the Japanese burrowing cricket, is a true cricket native to East Asia that was introduced to the eastern United States in 1959. The species exhibits two distinct life cycle modes: egg diapause and nymphal diapause, which vary geographically across its native range. In North America, it has expanded from the eastern seaboard to the eastern Great Plains and northern United States, with recent observations suggesting it is more mobile and potentially more ecologically impactful than previously assumed.
