Marmalade Hoverfly

Episyrphus balteatus, sometimes called the marmalade hoverfly  , is a relatively smallhoverfly (9–12 mm) of the Syrphidae family,

widespread throughout all continents. Like most other hoverflies it mimics a

much more dangerous insect, the solitary

wasp, though it is a quite harmless species. The upper side of the abdomen is

patterned with orange and black bands. Two further identification characters are

the presence of secondary black bands on the 3rd and 4th dorsal plates and of

faint greyish longitudinal stripes on the thorax.

 

E. balteatus can be found

throughout the year in various habitats,

including urban gardens, visiting flowers for pollen and nectar.

They often form dense migratory swarms, which may cause panic among people for

its resemblance to wasps. It is among the very few species of flies capable of

crushing pollen grains and feeding on them. The larva is

terrestrial and feeds on aphids.

 

As in most other hoverflies, males can be easily identified by their holoptic eyes, i.e., left and right compound eyes touching at the top of the head.
