“…Regarding the olive groves, contrary to what was previously reported by Villa et al (2021), our results indicate that the presence of this crop in the landscape had a weak negative effect on the abundance of M. mellinum . In the study conducted by Villa et al (2021), all the olive groves sampled had spontaneous ground cover vegetation. The vegetation cover in the agrosystems provides shelter and vital floral resources for the syrphids.…”

“…This low richness may be related to the sampling dates (early summer and autumn, instead of early spring). S. scripta and M. mellinum were the most abundant syrphids, in agreement with previous studies carried out in the Mediterranean region (Ricarte et al, 2011; Sabater & García, 2008; Villa et al, 2021). Larvae of both species are aphidophagous while adults feed on pollen and are active from the beginning of the spring to the middle of the autumn (Speight, 2017).…”

“…Our results indicated that syrphids were more abundant and richer in early July, most likely because the majority of plants bloom in spring, whereas in summer and autumn, syrphids would remain in diapause, concurring with Salveter (1998), Speight (2014), and Villa et al (2021). However, a relatively low number of species were identified compared with other studies in the vineyard (e.g., Gonçalves et al, 2015; Pétremand et al, 2017; Sommaggio & Burgio, 2014).…”

“…These habitats contain plants that bloom in July such as the trees C. sativa and Sambucus nigra L. or the scrubs Daphne gnidium L., Cytisus sp., Genista sp., Rubus sp. and Erica sp., all of them are well‐known food resources for syrphids (e.g., Villa et al, 2021; Wojciechowicz‐Żytko & Jankowska, 2016). Accordingly, to Kleijn and Van Langevelde (2006), Meyer et al (2009), and Schirmel et al (2018), syrphids depend on floral resources for adults, such as the quantity and quality of pollen and nectar, as well as the type of the SNH (woody or herbaceous) and on the presence of requirements for larval development.…”

“…The larvae of some species are voracious predators of insects and agricultural pests (Belcari & Raspi, 1989; Bellefeuille et al, 2019; Dunn et al, 2020; Hopper et al, 2011; Sacchetti, 1990), while others are decomposers (Martínez‐Falcón et al, 2012; Speight, 2017). The adults feed on nectar and pollen in flower plants (Rotheray & Gilbert, 2011; Villa et al, 2021), acting as pollinators (Doyle et al, 2020; Klecka et al, 2018; Raguso, 2020; Saunders, 2018). In addition, syrphids can also play an important role as bioindicators, as they have been proven useful in evaluating environmental health (Sommaggio & Burgio, 2014; Souza et al, 2014; Velli et al, 2010).…”

The intensification of urban and agricultural use in the landscape is the major driver of biodiversity loss and the consequent decrease of ecosystem services provided by insects. Syrphids are important ecosystem service providers, including pest regulation, pollination, and matter decomposition. Understanding how the surrounding landscape to crops affects syrphids is essential to implementing strategies to reverse the negative effects of the agricultural landscape's simplification. This study describes the Syrphidae community in Portuguese vineyards and the response of the most abundant species, Sphaerophoria scripta Linnaeus, 1758, and Melanostoma mellinum Linnaeus, 1758, to the landscape composition and configuration within a gradient of distances (500, 1000, and 2000 m) from the sampled vineyards. The presence of seminatural habitats and other crops in the surrounding landscape increased both species at the largest distance, whereas the presence of artificial territory, olive orchards, and vineyards reduce M. mellinum at some of the buffers. Increasing seminatural habitats in the vineyards surrounding landscape (2000 m) and, potentially, introducing nature‐friendly practices in the principal crops around vineyards may favour syrphid abundance.

Sustainability of agroecosystems depends on the ecosystem services, provided by beneficial organisms, such as the syrphids (Diptera: Syrphidae) acting as other‐insect predators and pollinators in different crops. In the case of olive groves, syrphids are predators of important pests and are endangered by the continuous intensification of agriculture, including landscape simplification. In this work, the effect of landscape structure on the abundance and species richness of syrphids in the olive agroecosystem of central Spain is assessed. Adult syrphids were sampled in 2015 and 2016 in the centre of circular areas of 15 olive grove landscapes (from 250 to 1500 m radius) representing a gradient of landscape complexity, in the province of Madrid, central Spain. The syrphid assemblage was made up of 57 species, although Eupeodes corollae, Eristalis tenax, Eristalis similis and Chrysotoxum intermedium made up 76% of the captures. Syrphid abundance and species richness were favoured in complex landscapes, with low olive grove area (CAO). Other landscape indices showed also this trend although their effect was not as strong and consistent as that of CAO. The area of scrublands (CAS) favoured syrphids in spring, but was unfavourable in autumn. The effect of Shannon's Evenness Index (SHEI) and mean shape index (MSI) was less consistent. The effect of CAO increased with increasing buffers radii, while the effect of CAS, SHEI and MSI was detected in general at smaller radii, indicating these indices affect different processes. Redundancy analysis (RDA) detected some differences between species regarding their abundance in spring versus autumn, and their relationship with landscape indices. This work provides new evidence that maintenance of complex landscapes is essential for maintaining functional biodiversity in the olive agroecosystem.
