Merodon equestris

(Merodon equestris)

Description

Merodon equestris (Narcissus bulb fly, greater bulb fly, large bulb fly, large Narcissus fly) is a Holarctic species of hoverfly (Family Syrphidae). Like many other hoverflies it displays a colouration pattern similar to a stinging insect (a bumblebee in this case) as an evolutionary defense mechanism. Other syrphid bee mimics are Mallota, Arctophila, Criorhina, Pocota and Brachypalpus. Merodon species are distinguished from these by the very strong hind femora, which bear a large triangular projection on the underside near the tip. It flies in low vegetation while the other bumblebee mimics prefer higher vegetation layers.
