Eumerus funeralis

Eumerus funeralis or lesser bulb fly[1] is a species of Hoverfly, from the family Syrphidae, in the order Diptera.[2][3] E. funeralis appears in Peck (1988) as a synonym of E. strigatus (Fallen), but was reinstated as the correct name for tuberculatus Rondani, sensu auctorum by Speight et al. (1998).

Female has frons with a large and squarish shiny area occupying its entire width except for the narrow white dust strips against the eye. Tergites are blackish, no red-brown markings. Van Veen, M. (2004) figures the male genitalia.[4][5][6][7] The larva is illustrated by Rotheray (1993) [8]


Distribution

Originated in the Mediterranean basin, but becoming cosmopolitan, especially in the Palaearctic and Nearctic.[9] [10][11]

Flowers visited include Euphorbia, Fragaria, Leucanthemum, Ranunculus. The flight period is April to September, with peaks in June and August. The larva is phytophagous, feeding in damaged bulbs. Minor pest of Amaryllis, Hyacinthus and Narcissus.[13]
