Blackburnʻs sphinx moth, Manduca blackburni (Lepidoptera: Sphingidae; Butler 1880), is a large sphinx moth endemic to the Hawaiian Islands. In 2000, it became the second moth and the first Hawaiian insect to be federally listed as an endangered species, yet little was known about its population biology. Its primary host plant is the invasive weed tree tobacco, Nicotiana glauca (Solanaceae). Despite the presence of tree tobacco on six of the seven main Hawaiian Islands, Blackburn’s sphinx moth is currently known from only Maui, Kahoʻolawe, and Hawaiʻi Island where it occurs at densities well below what its invasive host plant would seem to support. In order to facilitate conservation efforts, I set out to analyze changes and patterns in abundance, elucidate ovipositional preferences, and identify the factors responsible for the apparent population suppression of this charismatic Hawaiian moth all on its novel invasive host plant.
