Anticosti Island

During an inventory of insect diversity on Anticosti Island in 1993, we caught unprecedented numbers of Neospondylisupiformis (Mannerheim), a longhorned beetle rarely observed in eastern North America. All specimens were caught using 12-funnel Lindgren traps baited with 95% ethanol and α-pinene. This longhorned beetle was captured again in 2007 on Anticosti with the same traps. Other than that, seven specimens of N.upiformis were caught elsewhere in Quebec between 1993 and 2015. Only 14 specimens were found in the 45 most important insect collections of the province, the most recent specimen dating back to 1964. At least 90% of the captures came from old-growth balsam fir stands of the south-central part of the island. Seasonal flight activity ranged from early June to late July, but adult captures peaked in early July. Results suggest that Anticosti Island might be a hot spot for N.upiformis in eastern North America, particularly in its south-central part where old-growth balsam fir forests still exist.

Softwood Species

A total of 819 North American sawmills were surveyed concerning their production and distribution of balsam fir lumber. Seventy-one mills reported a total annual production of 275 million board feet (648 585 m3) of balsam fir lumber. The larger mills of eastern Canada represented 72% of this total. Canadian and large eastern US sawmills used middlemen heavily in marketing their softwood lumber while the remaining US sawmills used direct selling and captive retail yards as primary market channels. The only major production problem reported was the longer drying time needed for balsam fir lumber when compared to other northern softwood species.

Daphnia Catawba

Despite the importance of Daphnia in freshwater zooplankton assemblages, species boundaries in the genus are unclear. This study verifies the taxonomic validity of D. catawba by establishing its genetic divergence from other species of Daphnia that occur in eastern North America. In addition, it reveals the presence of a second, closely allied species, D. minnehaha, which had previously been placed in synonomy with D. pulex. Daphnia catawba and D. minnehaha share a preference for acidic habitats and are restricted to the deciduous and boreal forest regions of the eastern portion of the continent, where D. catawba is restricted to lakes, while D. minnehaha occurs in ponds. Both species reproduce by cyclic parthenogenesis and, based on the extent of their allozyme differentiation, last had a common ancestor more than 7 million years ago. Populations of D. minnehaha fall into two genetic clades; those from the Great Lakes watershed are morphologically divergent and have much lower levels of genotypic diversity than those from eastern Canada and the New England states.

Mite Genus

The oribatid mite genus Oribatella (Oribatellidae) includes 107 species worldwide, with 13 species reported for eastern North America. Herein, I describe six new Oribatella species from eastern North America: O. flagellata sp. nov., O. jacoti sp. nov., O. nortoni sp. nov., O. metzi sp. nov., O. texana sp. nov., and O. transtriata sp. nov. Oribatella metzi and O. nortoni are described on the basis of adults and immatures. The deutonymph and tritonymph of O. metzi lack dorsocentral setae dm and dp, and the diagnosis of the genus is expanded to accommodate these newly described immatures, and also newly described adult characters. I provide expanded, detailed diagnoses for previously described species of eastern North America: Oribatella arctica Thor, 1930, O. brevicornuta Jacot, 1934, O. dentaticuspis Ewing, 1910, O. gigantea Berlese, 1916, O. mediocris Berlese, 1916, O. minuta Banks, 1896, O. plummeri Jacot, 1934, O. pusilla Berlese, 1916, O. quadridentata Banks, 1895, O. reticulata Berlese, 1916, O. reticulatoides Hammer, 1955 and provide new distribution records where available. I question the specific status of O. extensa Jacot, 1934, and consider records of O. sexdentata Berlese, 1916 from eastern North America to be doubtful. Oribatella quadricornuta (Michael, 1880) is confirmed to occur in eastern Canada. Finally, I give a key to adults of the 18 species of Oribatella now known from eastern North America.

AbstractA spotted tentiform leaf miner, often present during recent years in large numbers in apple orchards in the Maritime Provinces of Canada, is identified as Lithocolletis blancardella Fabr., a species common on apples in Europe. Recent collecting indicates that the species occurs widely in Eastern Canada and the northeastern United States. Diagnostic characters, especially those of the male genitalia, are compared with those of specimens identified as L. crataegella Clem. and L. propinquinella Braun, two similar species which commonly occur on apple and black cherry respectively.

Butt Rot

Daedalea extensa Peck is an earlier name for Poria cocos Wolf, the fungus commonly called tuckahoe. Descriptions of the basidiomes and cultures are presented. In the northern deciduous forests of eastern North America the fungus typically occurs as a trunk and butt rot of mature, old-growth trees. The basidiomes appear after the tree has died. Reports of the fungus from Manitoba, Saskatchewan, and Alberta require confirmation because of confusion with the Canadian tuckahoe, Polyporus tuberaster Fr. Both D. extensa and Merulius sulphureus Burt are transferred to Macrohyporia.

Geometrid Moth

The geometrid moth Hemithea aestivaria (Hübner, 1789) was introduced from Europe to North America, first detected in British Columbia in 1973. Until 2019, its North American range was limited to a restricted area of the Pacific Northwest. Here, we report on the first records of H. aestivaria for eastern North America from three widely separated urban centers in eastern Canada during 2019-2020.

Abstract Metoposaurids are a widespread and ubiquitous constituent of Late Triassic non-marine paleoenvironments. In North America, this group is practically the only large-bodied temnospondyl clade, and is particularly well documented from the American southwest and south-central regions (Arizona, New Mexico, Texas). However, metoposaurids are poorly documented from eastern North America, with fragmentary, doubtfully diagnostic historical material such as “Dictyocephalus elegans” Leidy, 1856 and “Eupelor durus” Cope, 1866. The Zions View (early Norian?) locality in Pennsylvania preserves more-complete material, which previous workers noted as belonging to “Buettneria perfecta” Case, 1922 (=Anaschisma browni Branson, 1905). However, the material has never been described in a fashion that characterizes the anatomy or that justifies the taxonomic assignment, yet it would represent the most complete material in eastern North America and a substantial expansion of this taxon's geographic range. Here we redescribe the Zions View metoposaurid material in detail, differentiating it from Calamops paludosus Sinclair, 1917, the only other Late Triassic temnospondyl from the eastern seaboard, and demonstrating confident affinities with A. browni. Our study is the first to properly justify the taxonomic referral, underscoring the broader importance of proper documentation of voucher specimens, especially for potential geographic outliers. Anaschisma browni is thus the most widely dispersed metoposaurid. Its easternmost documentation underscores the importance of the undersampled and understudied metoposaurid record on the eastern seaboard for understanding the development of a metoposaurid zone of exclusivity in North America and demonstrates the need for further exploration to refine conceptualizations of Late Triassic tetrapod evolution.
