“…These captures were done for one to three hours by one to three collectors. Despite this method is a highly collector-dependent method (depending on his ability and expertise to capture flies) and not easily replicable, previous comparisons between collecting methods to establish which one is more appropriate for sampling different Calyptratae guilds demonstrated that active capture by highly trained collectors was the most reliable practice to obtain kleptoparasites (Olea et al, 2017).…”

Sarcophagid flies belonging to the subfamily Miltogramminae are mainly kleptoparasites of bees and solitary wasps. Twenty-six locations were surveyed to accomplish the first specific exploration on the diversity of Miltogramminae in southern Andean areas of South America. We evaluated changes in abundance, richness and composition among habitat types to establish the effect of anthropization on the Miltogramminae community. Habitat types were considered as human modified (trails and roads, parks and meadows) and natural sites (watercourses and lake beaches, sandy and shrubby areas), distributed in two ecoregions (Valdivian forest and Patagonian steppe). We found differences in the capture rate and composition of Miltogramminae among habitat types. The species Opsidia intonsa Aldrich was highly dominant in samples, with higher proportional abundance in human modified habitats. Richness of Miltogramminae was higher in natural sites. Comparisons between the ecoregions surveyed indicated the genus Opsidia Coquillett did not show differences in abundance between ecoregions, whereas Senotainia Macquart was more abundant in the Patagonian steppe. The results provide evidence on the significant effects of human influence on landscapes in kleptoparasitic fly diversity. Slight modifications of natural areas (as proliferation of trails or isolated houses) should be addressed to evaluate the conservation of kleptoparasitic Diptera.

“…Sampling was conducted for two consecutive years, 2014 and 2015, during the warmer, humid summer and colder, dry winter seasons. Adult flies were collected at each site with two traps exposed to different insolation conditions, sunlight and shade (total number of traps 26) baited with 200 g of hydrated bone meal (putrescine) (Olea et al, 2017), and hung with a cord from a pole or tree branch 1.5-2 m from the ground and at the shelter of the wind. The traps were adapted from Hwang & Turner (2005) and are described in detail in Battán-Horenstein et al (2016).…”

“…Compared to other saprophagous families, relatively little is known about the ecology of Neotropical sarcophagids. In Argentina, studies of Sarcophagidae inhabiting urban environments have only been performed in Buenos Aires and its surrounding areas, characterized by a humid subtropical climate without a dry season (Köppen‐Geiger climate classification: Cfa) (Mulieri et al ., 2011; Patitucci et al ., 2015), and in the southeast of Patagonia, characterized by a cold semidesert climate (Köppen‐Geiger classification: BWk) (Olea et al ., 2017). To our knowledge, there is little published information about the fauna and ecology of the Sarcophagidae in Central Argentina, where the climate is humid subtropical with dry winters (Köppen‐Geiger classification: Cwa).…”

The urbanization process affects the structure of insect communities, favouring biotic homogenization processes by promoting adequate conditions for the establishment of synanthropic species. Considering the scarce knowledge about the ecology of Neotropical sarcophagids, we compared the flesh fly community from two different urban zones in two contrasting seasons and examined the response of the Sarcophagidae assemblage to landscape and microhabitat variables. Adult flies were collected in 13 sites with two traps (total number of traps 26) baited with 200 g of hydrated bone meal. A total of 2312 adult sarcophagids were collected belonging to 27 species; Oxysarcodexia paulistanensis (Mattos, 1919) represented >48% of the total sample. The local factor of insolation explained both the abundance and species richness of sarcophagids, collections being higher and richer in traps exposed to sunlight compared with traps placed in the shade regardless of the season. Richness was also affected by the environment, being higher in traps exposed in suburban rather than urban sites. The combination of these factors (sub‐urban environment and availability of open areas) could explain the Sarcophagidae assemblage. The average number of sarcophagid species collected was related to the season, providing a good opportunity to assess the temporal variability of this family in the region.

“…(), amongst other. In addition, researchers have been investigating the diversity and seasonal dynamics of some saprophagous flies using different types of bait (Mulieri et al ., ; Patitucci et al ., ; Battán‐Horenstein et al ., ; Dufek et al ., ; Olea et al ., ). Differences in the performance of baited traps indicate that the type of decomposing organic matter can affect the assembly of species that are attracted, which could be expected because they may differ in terms of both their nutrient composition and their physical and chemical properties (Hanski, ).…”

1. Direct consumption of organic matter by the saprophagous larvae provides the ecosystem with a fundamental service by recycling nutrients and reducing exposure to decomposing matter. The present study aimed to assess the functional role of saprophagous flies in the mass loss of different types of decomposing organic matter.2. Two types of common urban waste were used to measure the role of flies in reducing organic matter: chicken viscera (chicken) and a mixture of flour and uncooked eggs (flour and eggs), representing leftover food. Ten traps baited with each substrate, under field conditions, allowed fly access (exposed to flies) and three traps from each substrate did not (unexposed controls); adult flies entering the traps or emerging from the substrates and substrate mass loss were recorded.3. Species from Calliphoridae, Sarcophagidae, Muscidae, and Fanniidae families were collected mainly in traps baited with chicken, with Phoridae being the most abundant in traps with flour and eggs as bait. A significantly richer (P < 0.05) assemblage of fly species accessed the traps baited with chicken viscera (21 species) compared with those emerging (11 species), whereas similar numbers of species accessed (n = 5) or emerged (n = 1) from traps baited with flour and eggs (average richness accessing 7.97, emerging 2.83). Chicken substrate mass loss and species richness were positively related (r = 0.56, P = 0.001). In traps where richness was larger than 10 species, the substrates were reduced by more than 85% of their initial weight compared with unexposed controls, which lost 30%. Substrate mass loss significantly increased with the abundance of flies (r = 0.73, P < 0.0001).4. The results of the present study support the functional role of saprophagous species diversity on the decomposition rates of organic matter, reinforcing the negative consequences of loss or gain of species in modified landscapes and for ecosystem function.
