Scale effects on the attachment pads and friction forces in syrphid flies (Diptera, Syrphidae).
To test the role of constructional and dimensional factors in the generation of friction force by systems of setose attachment pads, six species of syrphid fly (Platycheirus angustatus, Sphaerophoria scripta, Episyrphus balteatus, Eristalis tenax, Myathropa florea and Volucella pellucens) were studied using light and scanning electron microscopy. Flies were selected according to their various b...

متن کاملChecklist of the flower flies of Ecuador (Diptera, Syrphidae)
Syrphidae is one of the most speciose families of true flies, with more than 6,100 described species and worldwide distribution. They are important for humans acting as crucial pollinators, biological control agents, decomposers, and bioindicators. One third of its diversity is found in the Neotropical Region, but the taxonomic knowledge for this region is incomplete. Thus, taxonomic revisions ...
متن کاملThe forgotten flies: the importance of non-syrphid Diptera as pollinators
Bees, hoverflies and butterflies are taxa frequently studied as pollinators in agricultural and conservation contexts. Although there are many records of non-syrphid Diptera visiting flowers, they are generally not regarded as important pollinators. We use data from 30 pollen-transport networks and 71 pollinator-visitation networks to compare the importance of various flower-visiting taxa as po...
متن کاملDescriptions of three new species of the genus Cheilosia Meigen from China (Diptera, Syrphidae).
Three species of genus Cheilosia (Diptera, Syrphidae: Eristalinae) from China are described as new to science, Cheilosia bullabucca Barkalov & Ståhls sp. n., C. lamproptera Barkalov & Ståhls sp. n. and C. yunnanensis Barkalov & Ståhls sp. n.
