“…In the New World, Syritta flaviventris has been reported from several states in the United States (Thompson et al 1990;Sidhu and Biddinger 2014;Skevington et al 2019;GBIF 2020), Mexico (Colima: Ramírez-García 2010; GBIF 2020; Mexico State: Eloisa 2014; Flores 2017;and Nuevo León: Thompson et al 1990; GBIF 2020), Brazil (São Paulo: Fluke 1960; Rio Grande do Sul: Morales and Köhler 2008), Uruguay (Montevideo: GBIF 2020), Argentina (Buenos Aires, Santa Fé and Entre Ríos: Thompson et al 1976;GBIF 2020), and Chile (Valparaíso and Metropolitan region: Marnef 1967, as Austrosyritta cortesi Marnef, 1967, junior synonym of S. flaviventris; and Biobío: Montes 2020). Campos and Peña (1973) recorded S. flaviventris from Easter Island.…”

“…Two Syritta species are present in the Nearctic and the Neotropical Regions, i.e., S. pipiens (Linnaeus, 1758) and S. flaviventris Macquart, 1842, both introduced as a result of human expansion (Thompson et al 1990;Lyneborg and Barkemeyer 2005;Skevington et al 2019). These two synanthropic species can be easily distinguished based on the morphological characteristics provided by Thompson et al (1990) and Skevington et al (2019). Pérez-Bañón and Marcos-García (2000) described the larvae of S. flaviventris from Opuntia Mill.…”

“…Range records. Range records were determined using Skevington et al (2019a), using the same methods as Vezsenyi et al (2019). Specimens were divided into three categories, based on their distance to the nearest collected specimen of that species: near (less than 400 km), intermediate (400-800 km), and far (more than 800 km).…”

“…Once all previously pinned individuals were excluded, all specimens were critically point dried using a Leica critical point dryer (Leica EM CPD300, Leica Microsystems Inc., Concord, Ontario, Canada) and then pointed onto pins. Identifications were conducted using Skevington et al (2019a), supplemented by keys from Vockeroth (1992), Miranda et al (2013), and Young et al (2016).…”

Distribution of Syrphidae (Diptera) across northern Ontario

Syrphids (Diptera: Syrphidae) are a diverse and widespread family of pollinating flies. Their diverse life history traits not only allow them to thrive in a wide range of habitats but also make them potential bioindicators of environmental change. Here, we report on their distributions from a previously understudied and undeveloped part of northern Ontario that is a large part of the third-largest wetland in the world. Samples were collected from across the region between 2009 and 2016, using numerous sampling methods. Of the 122 species identified from 1514 specimens, six are new provincial records to Ontario. Five species were collected over 800 km from their previously known ranges, some of which were west of the Rocky Mountains. Of all the trapping methods employed in the study, Malaise traps were found to be the most effective at catching syrphid species. This work updates known range and provincial records for more than 100 species of syrphids, bringing into clearer focus their distribution throughout this region.

“…Eristalis arbustorum have filter-feeding rat-tailed maggot larvae that typically live in stagnant water while T. marginatus have terrestrial, aphidophagous larvae. Eristalis arbustorum adults are moderately sized (10-11 mm) while T. marginatus are small (5-6 mm) [33,34].…”

Can anthophilous hover flies (Diptera: Syrphidae) discriminate neonicotinoid insecticides in sucrose solution?

et al. 2020

Understanding how neonicotinoid insecticides affect non-target arthropods, especially pollinators, is an area of high priority and popular debate. Few studies have considered how pollinators interact and detect neonicotinoids, and almost none have examined for these effects in anthophilous Diptera such as hover flies (Syrphidae). We investigated behavioral responses of two species of hover flies, Eristalis arbustorum L. (Eristalinae) and Toxomerus marginatus Say (Syrphinae), when given a choice between artificial flowers with uncontaminated sucrose solution and neonicotinoid-contaminated (clothianidin) sucrose solution at field-realistic levels 2.5 ppb (average) and 150 ppb (high). We examined for 1) evidence that wild-caught flies could detect the insecticide gustatorily by analyzing amount of time spent feeding on floral treatments, and 2) whether flies could discriminate floral treatments visually by comparing visitation rates, spectral reflectance differences, and hover fly photoreceptor sensitivities. We did not find evidence that either species fed more or less on either of the treatment solutions. Furthermore, T. marginatus did not appear to visit one of the flower choices over the other. Eristalis arbustorum, however, visited uncontaminated flowers more often than contaminated flowers. Spectral differences between the flower treatments overlap with Eristalis photoreceptor sensitivities, opening the possibility that E. arbustorum could discriminate sucrose-clothianidin solution visually. The relevance of our findings in field settings are uncertain but they do highlight the importance of visual cues in lab-based choice experiments involving insecticides. We strongly encourage further research in this area and the consideration of both behavioral responses and sensory mechanisms when determining insecticidal impacts on beneficial arthropods.
