• Tortistilus wickhami

  A North American treehopper in the family Membracidae, recently documented for the first time in Mexico's Baja California peninsula. Previously known from the western and southwestern United States, this species was collected from grapevines in Valle de Guadalupe vineyards during 2023. Its presence in commercial vineyards raises concerns about potential economic impact, as it is suspected to be a candidate vector for grapevine red blotch virus.
