Full Text: Lesions resembling knemidokoptic mange on the feet and tarsometatarsi of 2 Hawaiian amakihi (Hemignathus virens) were observed while the researchers were mist netting wild passerines at Manuka Natural Area Reserve on the island of Hawaii between June 14, 2007 and June 19, 2007. During subsequent mist netting from September 2007 through February 2008, we found that 26% (7/27) of the Hawaiian amakihi caught were similarly affected. Microscopic examination of skin scrapings from lesions of affected individuals revealed Knemidokoptes jamaicensis (Acari: Knemidokoptidae). This is the first report of Knemidokoptes species found in wild passerines in Hawaii. No other wild passerines (n = 573) were found with knemidokoptic mange during our island wide study of Hawaiian amakihi.
