Vanduzea segmentata (Fowler) (Hemiptera: Membracidae): Seasonality and Habits in the Southeastern United States, with Review of Its U.S. Distribution and Host Plants

Abstract

Abstract.— Vanduzea segmentata, a membracid of the smiliine tribe Amastrini, was known only from the western United States and Mexico until it was reported from Louisiana in the 1930s. A collection in the Florida Panhandle in 1954 represented the first record east of the Mississippi River; the first record from peninsular Florida was 2001. The membracid has remained known in southeastern states only from Florida and Louisiana, with scant data available on its bionomics. We give the first records of V. segmentata from Alabama and Georgia, noting features that distinguish it from other species of Vanduzea in the Southeast, and review its previously published U.S. distribution and plant associations. We found nymphs and adults mainly on mimosa, or silk tree (Albizia julibrissin Durazz.; Fabaceae), but other fabaceous species and composites (Asteraceae) also were hosts. Periodic sampling of mimosa in southeastern Georgia indicated that the membracid is trivoltine, with overwintered eggs beginning to hatch in ...
