AbstractRecords obtained over a period of six years revealed that the Elaterid beetles in organic soils in southwestern Quebec emerged during the second and third weeks of May when the maximum soil temperature varied between 39 and 57°F and the maximum air temperature between 57 and 80°F. Males appeared earlier than females, the proportion of males becoming larger as the population decreased. Peaks of emergence occurred mostly during the first and second weeks of June when the air temperature varied between 74 and 82°F. Adult populations decreased from the beginning of June to disappear completely by the middle of July. The flight period lasted 73 and 52 days when the maximum daily temperature during the month of May averaged 62.4 and 70°F respectively. Of eleven species, Dalopius pallidus Br., Melanotus communis-fissilis complex and Agriotes mancus (Say) were the most numerous species collected in flight-traps, whereas Dalopius pallidus Br., Hypolithus abbreviatus (Say), Ctenicera tarsalis (Melsh.), Agriotes mancus (Say), and Aeolus mellillus (Say) were respectively the five most abundant species attracted by the solution of dilute molasses in heap-traps. Most of Elaterid beetles were captured when flying south. Beetles were captured at all heights from 15 to 75 inches. The population of adults decreased rapidly after two years of clean cultivation in the area surrounding the experimental plots.

The longhorn beetle fauna (Coleoptera: Cerambycidae) was studied in the Zselic region (Somogy county) in Hungary in seven consecutive years (2009–2015). In total 2,931 specimens were observed and the presence of 83 species was identified during the sampling period. The most abundant species were: Plagionotus arcuatus (Linnaeus, 1758) (p<sub>i</sub> = 10.542); Cerambyx scopoli Füssli, 1775 (p<sub>i</sub> = 8.359), Dorcadion aethiops (Scopoli, 1763) (p<sub>i</sub> = 6.653) and Strangalia melanura (Redtenbacher, 1867) (p<sub>i</sub> = 6.209). According to our examinations, individual meteorological factors, particularly temperature, directly influenced the dispersal and the activity of longhorn beetles (P = 0.038) as well as the species richness (P = 0.047), as did weather systems formation and movement of air masses, cold and warm fronts. It is also shown that the activity of the insects is influenced by daily weather conditions. The activity of arthropods was higher during warm, dry days and less pronounced during cold, wet ones coupled with high air pressure values. A conspicuous relationship was observable between the appearance of cerambycid beetles and their time period. According to the results of Principal Coordinate Analysis four major groups can be distinguished: early-flight, late spring-flight, summer-flight and late-flight species.

AbstractA total of 34 species of female tabanids were collected with CO2-traps from four different habitats near Guelph, Ont., during the 1971, 1972, and 1973 fly seasons. Nearly equal numbers of species were trapped at the Ontario Reformatory, Preston, Kortright, and the Hanlon Creek watershed, comprising a total of 15 Chrysops spp., 12 Hybomitra spp., 6 Tabanus spp., and 1 Atylotus sp. Relative abundance and flight periods are reported for each species. Chrysops frigidus O. S. and Hybomitra lasiophthalma (Macq.) were the most abundant species among their respective tribes; their abundance was related directly to degree of soil wetness, differing from that of Tabanus similis Macq. and T. quinquevittatus Wd. which was related inversely to these habitat types. The flight period of nearly 85% of the sampled population, consisting mainly of C. frigidus, H. lasiophthalma, and H. epistates (O.S.), spanned from the end of May till mid-July. T. quinquevittatus, T. lineola Fab., and H. epistates occurred till mid-September.

AbstractHorse flies (Diptera: Tabanidae) are hematophagous insects that cause direct and indirect losses in livestock production and are important vectors of pathogens. The aim of this study was to determine the diversity and seasonality of horse fly species at an experimental farm in Tacuarembó and the diversity of species in different departments of Uruguay. For 20 months, systematic collections were performed using Nzi and Malaise traps in two different environments at the experimental farm. Temperature, humidity and rainfall were recorded using a local climatological station. In addition, nonsystematic collections were made at farms located in the departments of Paysandú, Tacuarembó and Colonia. A total of 3,666 horse flies were collected, allowing the identification of 16 species. Three species were recorded for the first time in Uruguay: Dasybasis ornatissima (Brèthes), Dasybasis missionum (Macquart), and Tabanus aff. platensis Brèthes. A species that had not been previously taxonomically described was identified (Tabanus sp.1). In the systematic captures, the most abundant species were Tabanus campestris Brèthes, T. aff. platensis and D. missionum, representing 77.6% of the collected specimens. The environment was an important factor related to the abundance of horse flies, as well as the mean temperature. The horse fly season in Tacuarembó started in September and ended in May, with three evident peaks, the most important one during summer. No horse flies were caught during winter. Variations in the prevalence of species in the different departments were observed, indicating the need to carry out new sampling efforts in different areas.

Stromatoporoids are the principal framebuilding organisms in the patch reef that is part of the reservoir of the Normandville field. The reef is 10 m thick and 1.5 km2in area and demonstrates that stromatoporoids retained their ability to build reefal edifices into Famennian time despite the biotic crisis at the close of Frasnian time. The fauna is dominated by labechiids but includes three non-labechiid species. The most abundant species isStylostroma sinense(Dong) butLabechia palliseriStearn is also common. Both these species are highly variable and are described in terms of multiple phases that occur in a single skeleton. The other species described areClathrostromacf.C. jukkenseYavorsky,Gerronostromasp. (a columnar species), andStromatoporasp. The fauna belongs in Famennian/Strunian assemblage 2 as defined by Stearn et al. (1988).

Benthic macroinvertebrates were sampled seasonally in the subtidal and upper and lower swash zones at two sites in each of six nearshore habitat types on the lower west coast of Australia. The habitat types, which differed mainly in the extent of their exposure to wave activity and whether sea grass and/or nearshore reefs were present, had been distinguished quantitatively using values for a suite of seven statistically-selected enduring environmental characteristics (Valesini et al., 2003). The core samples yielded 121 species representing eight phyla, among which the Polychaeta, Malacostraca and Bivalvia were the most speciose classes, contributing ∼38, 23 and 10%, respectively, to the total number of individuals. The total number of species and mean density of macroinvertebrates at the most protected habitat type (1), i.e. 70 and 209·2 individuals 0·1 m−2, respectively, were far greater than in any other habitat type. Habitat type influenced species composition to a greater extent than either zone or season. Furthermore, the extents of the differences among the species compositions of the six habitat types statistically matched the extents of the differences among the values for the suite of enduring environmental characteristics that distinguished each of those habitat types. Overall, the species composition at habitat type 1 was the most distinct, containing five abundant species of polychaetes that were adapted to deposit-feeding in calm waters with high levels of organic material and which were rare in all other habitat types. In contrast, the fauna at the most exposed habitat type was characterized by four crustacean species and a species of bivalve and polychaete, whose mobility and tough external surface facilitated their survival and feeding in turbulent waters. The zonal differences in faunal compositions among habitat types were greatest in the case of the subtidal zone. The faunal compositions differed among zones and seasons only at the most protected habitat type.
