Three "Must-See" 3D Membracidae
We thank Milan Kozánek (CEO, VirNat, Bratislava, Slovakia) for sharing links to three amazing 3D models of treehoppers collected in the Philippines. A collaborator of the Treehoppers Partnership since 2016, Milan previously shared images of  Thuris and Ecuadorian stamps based on his photos (see “archives of past news”: 2016-02-16, 2016-02-18, 2016-03-03). Matthew S. Wallace and Stuart H. McKamey identified the three treehoppers below. As soon as a 3D model has loaded, you can zoom and manipulate the model using your mouse. Enjoy.

Early Treehopper Publications Online: Panzer 1802a, Petagna 1820a, and Thunberg 1822a
On 16 October 2015, the Treehopper News (see archive of past news) presented a “Guide to Treehopper Workers of the 1700s and Their Publications,” which gave direct links to most contributions by these early entomologists. Recently we discovered links to three more of these works available from the Biodiversity Heritage Library, as follows: Panzer 1802a; Petagna 1820a; and Thunberg 1822a.

We still hope to find online copies of: Goeze, A. E. 1780a; Höslin, P. 1782a; Müller, P. L. S. 1774a; Petagna, V. 1808a [for detailed citations search the Metcalf Literature Collection Database].

New State Records for Thelia bimaculata and Vanduzea arquata
Wheeler, A. G., Jr. 2021a. An introduced tree, black locust, and its non-native treehoppers augment Nebraska's biodiversity. Great Plains Research 31: 17–33. [This publication includes color photos of Thelia bimaculata and Vanduzea arquata and a map of their distributions in Nebraska and South Dakota.]

Wheeler (2021a) published the first distribution records of two treehoppers--Thelia bimaculata and Vanduzea arquata--in the states of Nebraska and South Dakota. The principal host for these hoppers is black locust, Robinia pseudoacacia, a tree originally native to the Eastern United States. Owing to its ornamental, ecological, and economic value, black locust has been introduced more widely. Thus, as chronicled by Wheeler (2021a), the two associated treehoppers likely became established in more western areas through the planting of egg-infested saplings. Deitz and Wallace (2012a) summarized prior distribution records of Nearctic treehoppers, including T. bimaculata and V. arquata.
