The Dead Head Hoverfly, Myathropa florea, above, owes its common name to markings on its thorax which are said to resemble
a human skull - someone needs a good optician. It is a medium (no pun) to large hoverfly prevalent over much of UK, Europe and North Africa.
The "skull" pattern is variable, - Blondie above right having more white than is usual.
It is also called the Batman Hoverfly because of the perceived batlike marking on the thorax.
The Dead Head Hoverfly is a wasp-mimic for protective camouflage.
