“…Different taxa associated with flowers were recorded, though bees and flies dominated the network, groups of insects that have been recognized by several authors as the main pollinators of cultivated and wild plants (Kremen et al, 2007;Aizen et al, 2009;Garibaldi et al, 2013;Sengupta et al, 2018). Honey bees (Apidae) and flies of the family Bibionidae and Syrphidae were the dominant flower visitors of all four deciduous fruit trees.…”

Pollination is essential to fruit production. How plant diversity and blooming events in and around orchards affect the pollinator community and the plant-flower-visitor network in neotropical systems remains largely unknown. 2 We surveyed the flower visitors in deciduous fruit trees and alternative blooming resources (other crops, hedgerows and weeds) in Colombia across 6 orchards over 12 months. We evaluated whether plant species richness and blooming cover influenced abundance and richness of flower visitors, as well as network-level connectance and specialization. We also assessed the role of alternative blooming resources for the flower visitors of deciduous fruit trees. 3 Overall, we found 66 taxa of flower visitors, 35 of which visited deciduous fruit trees.There was a greater abundance of flower visitors when there was higher richness of weedy species and greater blooming cover of deciduous fruit trees. Networks were less connected when there was lower crop and weedy species richness. Finally, flower visitor abundance and specialization increased when there were multiple hedgerow species in bloom with a high blooming cover. 4 We highlight the importance of maintaining alternative blooming resources in and around the orchards to support deciduous fruit tree pollinators and diversity in the plant flower-visitor network.

The current investigation focused on dipteran species that visit flowers in the trans-Himalayan region of Kargil district, Ladakh U.T, India. Surveys were conducted on various field and fruit crops across different locations at elevations ranging from 2650 to 4500 ft. A total of 17 dipteran species, encompassing 15 genera, 11 tribes, and 9 subfamilies, were documented during the flowering season of fruit and field crops for more than two years from May 2020 to October 2022 excluding the winter season.

“…The adult hoverflies mainly depend upon the nectar of flowering plants for their food and energy, whereas females use pollen for ovarian maturation (Doyle et al 2020). The major identifying character is the presence of spurious vein or false vein (few exceptions in genera Graptomyza and Paragodon along with species Syritta flaviventris), which lies between the third (R4 + 5) and fourth (M1 + 2) longitudinal veins of the wings extending longitudinally and slightly diagonally (Sengupta et al 2018). Some hoverfly species are specific in their habitat preferences and thus, exhibit a narrow distributional range, whereas some species have a wide distributional range across several habitats (Sengupta et al 2016).…”

Abstract. Budhathoki N, Dhakal S, Dyola U. 2021. Diversity of hoverflies (Diptera: Syrphidae) in Nagarjun, Shivapuri Nagarjun National Park, Nepal. Biodiversitas 22: 5382-5388. Hoverflies are recognized as potential pollinators of a wide range of wild plants. This study explored the abundance and diversity of hoverflies over three different seasons from October 2018 to April 2019 in two different study sites, i.e. forest and grassland at Nagarjun of Shivapuri Nagarjun National Park, Nepal. Each site of the study area was further divided into five sampling transect stations. Hoverflies were collected from each station by using two methods as pan trap sampling and transect sweeping sampling. Overall, a total of 373 specimens representing 13 species under nine genera of two subfamilies (Syrphinae and Eristalinae) were recorded. The abundance and diversity of hoverflies varied seasonally, the maximum number of individuals and diversity were recorded from the spring season, whereas the minimum number of individuals and diversity were found in the winter season. In addition, forest habitat consists of the highest abundance and diversity of hoverflies, whereas grassland consists of the lowest abundance and diversity. The analysis done by using generalized linear modeling (GLM) revealed climatic parameters such as temperature and humidity had a varying effect on the abundance of hoverflies. However, both these parameters had not any significant influence on the number of hoverfly species.
