Yucca Plant Bug, Halticotoma Valida: Authorship, Distribution, Host Plants, and Notes on Biology
Abstract
Authorship of the yucca plant bug, Halticotoma valida, has been credited to Reuter, 1913, but Townsend, 1892 is recognized as validating Uhler's manuscript name of H. valida. The known distribution is reviewed and 7 new state records are given. Host plant records are discussed, and those from cactus and orchids are considered to be based on misidentifications. In North Carolina eggs hatched in late March, and first generation adults were abundant by 1 May. Nymphal first-instars of the second generation were present by 1 June, and adults were common by 1 July. At least 2 more generations occurred before killing frosts. Yucca recurvifolia and Y. filamentosa were more susceptible to injury by yucca plant bug than the thicker-leaved Y. aloifolia and Y. gloriosa.Downloads
