Merodontini
Merodontini is a tribe of hoverflies (Diptera: Syrphidae) within the subfamily Eristalinae. The tribe includes genera such as Merodon, Eumerus, and Psilota. Larvae of Merodon and Eumerus tunnel into plant bulbs, while Psilota larvae have been found in sap runs. Some species, particularly Eumerus strigatus, are phytophagous and pose potential risks to agricultural crops such as onion (Allium cepa). The tribe has been recorded across multiple continents including the Palaearctic, Afrotropical, and Neotropical regions, with new species and distribution records continuing to be documented.
