Studies of the goldenrod gall caused by Eurosta solidaginis Fitch have been made by various authors who reared insects from the galls in North America, e.g. Hughes (1934), Milne (1940) and Ping (1915). Snyder (1898) described the emergence of an adult fly from a gall in Illinois. In Canada, insects have been reared from galls collected in Manitoba and the Northwest Territories by Brodie (1892), in Quebec by Fyles (1894) and in Ontario by Harrington (1895). An opportunity has been taken recently to examine specimens reared by Dr. G. Beall from galls collected at Chatham, Ontario in 1930 and to rear insects from galls in the vicinity of London, Ontario.

Eurasian Species

The frequency of the middorsally striped morph of Rana sylvatica in Ontario and Manitoba varies from absence in southern Ontario to 80% on the coast of Hudson Bay, with a general value of 20–30% in the boreal forest, a rise to 50% on the forest–grassland ecotone in southern Manitoba, and a decline westward to 20% on the edge of the prairies. This morph is rare in the northeastern United States and Maritime Canada. The suggested relationship between its frequency and the "grassiness" of the background on which predators view it is reexamined, and it is suggested that a linkage with earlier transformation as demonstrated in Eurasian species may explain certain anomalies.

Plauditus cestus (Provonsha & McCafferty, 1982) is widespread in eastern and central North America. We provide new data from Virginia that fill a gap in the range of distribution and new data from the Northwest Territories that extend the range of the species by over 1900 km to the northwest. The Northwest Territories specimen represents a new larval color variant, with pronounced coloration of abdominal segment 6. We emphasize the need for additional sampling of aquatic habitats in the Far North.

Glaucopsyche Lygdamus

The couperi subspecies of the Silvery Blue (Glaucopsyche lygdamus couperi) has expanded its range southward in northeastern North America using introduced legumes and open anthropogenic habitats. The discovery of a population of the Silvery Blue (Glaucopsyche lygdamus) in an eastern Ontario alvar woodland in 2011 suggests that the Silvery Blue may have been long established (although restricted) in southern Ontario. Three larvae from this population were reared from eggs deposited on native Neglected Milk-Vetch (Astragalus neglectus) by free-flying females in 2012. The three larvae, pupae, and single reared adult, as well as other adults from the alvar woodland, are described and compared with specimens associated with open anthropogenic habitat and introduced legumes. The alvar woodland specimens were closer to the northern Ontario subsp. couperi than to the subsp. lygdamus of the eastern United States. Although the alvar woodland larvae were darker green than subsp. couperi and the spots on the adults were on average larger than in subsp. couperi, the alvar woodland Silvery Blues could not be definitively distinguished from subsp. couperi, including specimens from northern Ontario and those from southern Ontario associated with open habitats. Nevertheless, there is a possibility that the alvar woodland population of the Silvery Blue dates from early postglacial times and represents a distinct race separate from the Silvery Blue of open habitats.

Mating Behaviors

The mating behaviors of Philodromus rufus-like spiders from the Pacific coast, northern Ontario, and southern Ontario near Belleville revealed two species and a subspecies. P. rufus Walckenaer is identified as a transcontinental species in which the males vibrate their legs in courtship and possess an "angular" retro-lateral apophysis on the palpal tibia. P. rufus vibrans Dondale is a small, heavily-speckled subspecies of rufus. The second species is P. exilis Banks, in which the males do not vibrate and have a "non-angular" apophysis, and which occurs in the Great Lakes-St. Lawrence-Acadian forests of eastern North America.

Rich Fauna

A moderately rich fauna of graptolites, comprising species dominated by Monograptus (sensu stricto), Retiolites, Stomatograptus, and Cyrtograptus is documented from Prairie Creek, southern Mackenzie Mountains, Northwest Territories. Graptolites of the upper Llandovery Monograptus turriculatus, Monograptus spiralis, and Cyrtograptus sakmaricus zones and of the Wenlock "unnamed zone" and Cyrtograptus rigidus and Monograptus testis – Cyrtograptus lundgreni zones are recognized. The species composition of these zones is significantly different from corresponding zones elsewhere in the Canadian Cordillera.Twenty-six species are described and illustrated, and of these, two are new: Stomatograptus canadensis and Cyrtograptus preclarus; and two species, Monograptus aff. riccartonensis and Cyrtograptus aff. sakmaricus might also be new. Several species, particularly Monograptus praecedens, Monograptus veles, and Monograptus cf. mutuliferus strigosus have not been prevously reported in North America.

Additional Control

Two introduced windgrass species have become crop weeds in North America. Common windgrass is a major weed of winter cereals in Europe and was first documented in North America in the early 1800s. It is a weed of roadsides and waste areas in the northeastern United States and in winter grain fields of southern Ontario and Michigan. Interrupted windgrass was first reported in North America approximately 90 yr ago; it is adapted to more arid sites than common windgrass and is distributed predominantly in the northwestern U.S.A. During the past 10 to 15 yr, interrupted windgrass has adversely affected winter grain and grass seed producers in the Pacific Northwest due to additional control costs.

A series of small road cuts of lower Boyle Formation (Middle Devonian: Givetian) near Waco, Kentucky, has produced numerous specimens of three blastozoan clades, including both “anachronistic” diploporan and rhombiferan “cystoids” and relatively advanced Granatocrinid blastoids. This unusual assemblage occurs within a basal grainstone unit of the Boyle Limestone, apparently recording a local shoal deposit. Diploporans, the most abundant articulated echinoderms, are represented by a new protocrinitid species, Tristomiocystis globosus n. gen. and sp. Glyptocystitoid rhombiferans are represented by isolated thecal plates assignable to Callocystitidae. Three species of blastoids, all previously undescribed, include numerous thecae of the schizoblastid Hydroblastus hendyi n. gen. and sp., the rare nucleocrinid Nucleocrinus bosei n. sp., and an enigmatic troosticrinid radial. The blastoid Nucleocrinus is typical for the age; however, the callocystitid, schizoblastid, and protocrinitid are not. Hydroblastus is the oldest known schizoblastid. Middle and Upper Devonian callocystitids have been previously reported only from Iowa and Michigan USA with unpublished reports from Missouri USA and the Northwest Territories, Canada. This occurrence is thus the first report of a Middle Devonian rhombiferan from the Appalachian foreland basin. Tristomiocystis is the first known protocrinitid in North America and the only protocrinitid younger than Late Ordovician. This occurrence thus represents a range extension of nearly 50 million years for protocrinids. This extraordinary sample of echinoderms in a Middle Devonian limestone from a well-studied area of North America highlights the incompleteness of the known fossil record, at least in fragile organisms such as echinoderms.

From inoculation experiments and morphological examinations, the aecial state of Pucciniastrum sparsum (Wint.) E. Fisch. (= Thekopsora sparsa (Wint.) Magn.) has been identified for the first time in North America from specimens collected in the Northwest Territories and the Yukon Territory. Picea glauca (Moench) Voss, P. mariana (Mill.) BSP., and P. pungens Engelm. (from inoculation only) are reported as new hosts of this fungus. An expanded description of the spermogonia and aecia of the fungus is given.

Relict Populations

AbstractSeventy-three species of the acalyptrate family Sphaeroceridae are recorded from Canadian peatlands, largely on the basis of pan trap samples from peatlands in southern Ontario, the Yukon, and Alberta. Spelobia nana (Rondani), Spelobia ibrida (Roháček), and Trachyopella atomus (Rondani) are newly recorded from North America. Fifteen species are identified as characteristic of peatlands, and their distributions and relationships are discussed. Southern peatland populations of several of these species are interpreted as relict populations in peatlands serving as post-Pleistocene refugia. Some species are known so far only from peatlands along the postglacial fringe.
