52/2013 Week 30

I’m taking a bit of a break from photography over the next week, mainly due to relations visiting. But I still have to fit in at some time a photograph for the weekly photo challenge. So it’s down to a quickie in the back garden using Live View and Focus Peaking. I can’t call this a macro photograph because I don’t have a macro lens, so lets just say this is a “close-up”

If I’ve got my identification right this is Episyrphus balteatus, sometimes called the marmalade hoverfly, a relatively small hoverfly (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 third and fourth dorsal plates and 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 their 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 their heads

  2. I continue to forget the title to your blog.I think I have erased some of your posts. For some reason I chose to check this one out thinking, “hum, I don’t remember subscribing to that blog but I had better look to see what it’s all about.”

    Anyway, great photo. I could not tell that this was not a macro. Excellent shot of the hoverfly.
