Manduca blackburni
Manduca blackburni, the Hawaiian tomato hornworm, Hawaiian tobacco hornworm or Blackburn's sphinx moth, is a moth in the family Sphingidae. Taxonomy 
Manduca blackburni is closely related to the tomato hornworm (M. quinquemaculata), which it also physically resembles. The species was first described by Arthur Gardiner Butler in 1880. Distribution and habitat 
It is endemic to Hawaii. Previously known from all of the main islands, this rare moth is now limited to Maui, the Big Island, and Kahoolawe. It is found in coastal mesic and dry forests at elevations from sea level to . Diet and ecology 
Larvae feed on plants in the nightshade family, Solanaceae, especially native aiea (Nothocestrum spp. ), but also non-native tomatoes (Solanum lycopersicum), tobacco (Nicotiana tabacum), tree tobacco (N. glauca), jimson weed (Datura stramonium), and eggplant (Solanum melongena). The adult feeds on nectar from native plants such as koali awa (Ipomoea indica) and maiapilo (Capparis sandwichiana). Conservation 
It was listed as an endangered species by the United States Fish and Wildlife Service in 2000, making it the first Hawaiian insect to receive such a status. NatureServe considers the insect to be Critically Imperiled. References
