蜜蜂、食蚜蝇和蝴蝶是农业和保护环境中经常研究的传粉者分类群。虽然有许多记录的非食蚜双翅目访花，他们通常不被视为重要的传粉者。利用30个传粉网络和71个传粉媒介网络的数据，比较了不同访花类群作为花粉载体的重要性。我们特别比较了非食蚜双翅目和食蚜科，以确定文献中对前者的忽视是否合理。我们发现，在食蚜双翅目昆虫和非食蚜双翅目昆虫之间，花粉负荷没有显著差异。此外，在花粉运输网络中，两组之间的专业化水平没有显著差异，尽管食蚜科的访问均匀性显著高于其他类群。33个农场的访花数据表明，在农业研究中，非食蚜双翅目占访花双翅目的大多数（平均丰度为82%，物种丰富度为73%），估计非食蚜双翅目携带的花粉占农田双翅目携带花粉总量的84%。由于重要的传粉媒介，如蜜蜂，已经遭受了严重的下降，这将是谨慎的，以提高我们对非食蚜双翅目昆虫作为传粉媒介的作用的理解。
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 pollen-vectors. We specifically compare non-syrphid Diptera and Syrphidae to determine whether neglect of the former in the literature is justified. We found no significant difference in pollen-loads between the syrphid and non-syrphid Diptera. Moreover, there was no significant difference in the level of specialization between the two groups in the pollen-transport networks, though the Syrphidae had significantly greater visitation evenness. Flower visitation data from 33 farms showed that non-syrphid Diptera made up the majority of the flower-visiting Diptera in the agricultural studies (on average 82% abundance and 73% species richness), and we estimate that non-syrphid Diptera carry 84% of total pollen carried by farmland Diptera. As important pollinators, such as bees, have suffered serious declines, it would be prudent to improve our understanding of the role of non-syrphid Diptera as pollinators.
