Eumerus funeralis
Lesser Bulb Fly
Eumerus funeralis, commonly known as the Lesser Bulb Fly, is a small hoverfly in the family Syrphidae. Originally described from the Mediterranean basin, it has become cosmopolitan in distribution, particularly widespread in the Palaearctic and Nearctic regions. The species is notable for its phytophagous larvae, which develop in damaged bulbs and are recognized as a minor pest of ornamental plants including Narcissus, Hyacinthus, and Amaryllis.
Merodon equestris
Narcissus bulb fly, greater bulb fly, large bulb fly, large Narcissus fly
Merodon equestris is a Holarctic hoverfly (Syrphidae) and a significant horticultural pest of bulbous plants. Adults are bumblebee mimics with variable coloration controlled by multiple genetic loci, flying low in zig-zag patterns April through July. Larvae develop internally within bulbs of Amaryllidaceae and Liliaceae, particularly Narcissus, causing economic damage in cultivated settings.
Rhopalosiphoninus latysiphon
bulb-and-potato aphid
Rhopalosiphoninus latysiphon is an aphid species that infests subterranean plant parts, particularly potato roots and bulbs of ornamental plants such as tulip and gladiolus. Its common name reflects its association with both bulb crops and potatoes. The species is distinguished by its preference for cool, damp environments and avoidance of above-ground foliage under normal field conditions. Two subspecies have been described but may be synonyms.
