E. D. Ball’s Publications on Treehoppers
American entomologist Elmer Darwin Ball (1870–1943) was a specialist on treehoppers and other Auchenorrhyncha. Born in Vermont, he graduated from Iowa State College (B.S., M.S.) and Ohio State University (Ph.D.). Working briefly as a school teacher, Ball had an energetic career with appointments across the U.S.: Albion Seminary (assistant principal), Iowa State College (taught entomology and zoology; later, department head), Colorado Agricultural College (taught entomology and zoology), Utah Agricultural College (professor), the United States Department of Agriculture, the Florida State Plant Board, and the University of Arizona (dean of the College of Agriculture; director of the Agricultural Experiment Station). Moreover, he also served as the State Entomologist of Wisconsin and as the Assistant Secretary of Agriculture. Ball’s extensive collection is now held by the National Museum of Natural History, Washington, D.C.

Regarding treehoppers, Ball described one subfamily (Stictocephalinae, now a junior synonym of the tribe Ceresini), 6 new genera (Bajulata, Bryantopsis, Grandolobus, Helonica, Palonica, and Telonaca–all remain valid), 58 new species (52 remain valid--3 are now also nominotypical subspecies), and 13 subspecies (all remain valid, including 1 elevated to species).

Plate 1 from Ball 1903a shows 9 new species he described in the genus Telamona: Fig. 1, T. extrema; 2, T. obsoleta [= T. westcotti]; 3, T. viridia [now in Palonica]; 4, T. ehrhorni [= Heliria sinuata]; 5, T. compacta; 6, T. decorata; 7, T. pruinosa [= T. collina]; 8, T. brevis [= Telamonanthe pulchella]; 9, T. pulchella [now in Telamonanthe].

Publications of E. D. Ball. All but three of Ball’s works on treehoppers are currently available online through the Biodiversity Heritage Library: Ball 1903a; Ball 1905a; Ball 1915b; Ball 1918a; Ball 1920b; Ball 1925a; Ball 1931f [needed (monograph of the tribe Telamonini)]; Ball 1932b [needed (food plants of various groups)]; Ball 1932c; Ball 1933a; Ball 1937d; Osborn and Ball 1897a [needed (hemipteran fauna of Iowa)].

New State Records of Treehoppers for Pennsylvania
Barringer, L. E. 2015a. Occurrence of treehopper (Hemiptera: Membracidae) bycatch on purple panel traps and Lindgren funnel traps in Pennsylvania, with new state records. Great Lakes Entomologist 48(3-4): 172-185.

Surveys incorporating Lindgren funnel traps and purple panel traps in Pennsylvania (2009-2013) captured 57 native treehopper species, including four not previously reported for the state: Heliria gibberata Ball 1925, Palonica pyramidata (Uhler 1877), Telamona projecta Butler 1877, and Telamona westcotti Goding 1893. Barringer’s work suggests that, with proper site selection, Lindgren funnel traps may be especially useful in monitoring the seasonal distribution of treehoppers, particularly species in the tribes Smiliini and Telamonini.

Updates to Treehoppers Team Members and Collaborators
We welcome graduate student Camilo Flórez-Valencia as the newest member of the Treehoppers "Taxa Content Team." A native of Colombia, Camilo is currently working towards his Master’s degree with Brazilian treehopper researcher Olivia Evangelista. One of Camilo's photos, a Colombian Anobilia, is shown below.

New collaborators include entomologists René Limoges and Stéphane Le Tirant (Montreal Insectarium, Montréal, Québec, Canada). Two of René’s recent treehopper photographs from Mindo, Ecuador, are featured below. See our Acknowledgments and archive of past news (posting of 2015-05-12), for further listings of Team Members and Collaborators.

Treehopper Publications of E. P. Van Duzee and L. B. Woodruff
Most works on treehoppers by American entomologists Edward Payson Van Duzee (1861-1940) and Lewis Bartholomew Woodruff (1868-1925) are readily available online through the Biodiversity Heritage Library (BHL). Two of Woodruff’s papers (1923a, 1924a), not currently available at BHL, are accessible through the digital library JSTOR (see Options for Access). For detailed citations of the works by either author, enter his last name in the author search box of DrMetcalf. We note that "Van Duzee 1890a,” which seems to treat only extant leafhoppers, was apparently listed in Metcalf and Wade’s 1963 bibliography on treehoppers and fossil Auchenorrhyncha in error.

Hemipterist Edward P. Van Duzee described 3 treehopper genera (Idioderma, Tylocentrus, and Xantholobus), 43 species (36 now valid, including 2 that are also nominotypical subspecies) and 3 subspecies (2 now valid subspecies, 1 invalid). The California Academy of Sciences, where Van Duzee served as curator (1916-1940), holds his collection of Hemiptera (164,442 specimens). Van Duzee’s 1908a plates 1 and 2, below, show simple line drawings of representative North American treehoppers.

Van Duzee’s Treehopper Publications: Van Duzee 1889b; Van Duzee 1890c; Van Duzee 1892d; Van Duzee 1893b; Van Duzee 1894e; Van Duzee 1895e; Van Duzee 1905a; Van Duzee 1906a; Van Duzee 1907a; Van Duzee 1908a; Van Duzee 1908b; Van Duzee 1909a; Van Duzee 1909c; Van Duzee 1912a; Van Duzee 1912b; Van Duzee 1914a; Van Duzee 1914c; Van Duzee 1916a; Van Duzee 1916b; Van Duzee 1917a; Van Duzee 1917b; Van Duzee 1923a; Van Duzee 1925b.

Lewis B. Woodruff authored 18 treehopper species (16 now valid) and 2 subspecies (1 now elevated to species, 1 invalid), all belonging to the tribe Smiliini. See our news posting of 2012-09-14 [archive of past news], for further information on Woodruff, who at one time had a desk at the American Museum Natural History. The following plates are from Woodruff 1915a (pl. 4, figs. 1-5, now Atymna helena); fig. 6, now A. querci) and 1919a (pl. 23; Ophiderma spp. [Woodruff’s captions include some junior synonyms]).

Woodruff’s Treehopper Publications: Woodruff 1915a; Woodruff 1919a; Woodruff 1920a; Woodruff 1923a; Woodruff 1924a.
