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).
Wing length: 3.5–6 mm (0.14–0.24 in).
Stigma are dark brown blackish. Femur 3 has a small ventral process at the base and apical to this projection a bare, shiny area. 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]
The habitat is open ground, dry grassland and clearings in dry woodland.[12] Occurs also in suburban gardens and land used for horticulture. 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]
