Ephraim Porter Felt ( 7 January 1868 Salem – 14 December 1943 ) was an American entomologist who specialised in Diptera . Felt worked mostly with Nematocera , particularly Cecidomyiidae . However , as State Entomologist for New York , the scope of his work included all insects of economic or medical significance . He wrote '' Insects Affecting Park and Woodland Trees '' ( New York State Museum Memoir 8 , 1905-1906 ) and '' Plant Galls and Gall Makers '' ( Ithaca , N.Y. , Comstock Pub . Co. , 1940 ) , and described over 1,000 species in scientific journals . He described the mosquito genus '' Culiseta '' . The holotypes of the Felt-named insect species are in the National Museum of Natural History . He was the great grandfather of Edward P. Felt ( 1959 – 2001 ) , a victim aboard United Airlines Flight 93 during the attacks on September 11 , 2001
