RESULTS The Kahului Airport Access Road - Phase 1 project area was re-surveyed on June 25, 2011, for Blackburn's sphinx moth host plants in the Nightshade Family. The entire 15.5 acre corridor was covered on foot. The results of the survey were as follows: • No tree tobacco plants were found within the project area, and none were even visible on adjacent lands as far as the eye could see. • One large cherry tomato plant was found growing on a steep bank on a developed, adjacent property to the southeast of the project area. This plant was examined and no Blackburn's sphinx moths, their eggs or larvae were detected. •
One dead jimson weed plant was seen on the same adjacent property near the tomato plant. This plant, which was growing alongside a hibiscus hedge, appeared to have been killed by herbicide and could not be adequately assessed.
• Several apple-of-Peru (Nicandra physalodes) plant were scattered around the project area. These plants, which have no known connection with Blackburn's sphinx moths, were dry and had gone to seed, and no sign of former feeding activity could be observed.
CONCLUSIONS The results of the re-survey revealed three species of plants in the Nightshade Family, but, no tree tobacco plants on or near the project area were found. No signs of Blackburn's sphinx moths, their eggs or their larvae were found on the few marginal Nightshade Family plants observed. These findings corroborate the conclusions reached in the 2008 study which were and remain that this project will not have any significant negative impacts on the endangered Blackburn's sphinx moth populations in central Maui.
