HOVERFLIES: Some common Lancashire hoverflies

August 25-27, 2010:
A few photographs of some local hoverflies are below. Identification to species level (and even to genus) can often be difficult. Some of those shown are only named tentatively and therefore open to correction.

  1. Hi Michael

    I'm no expert but wondering if the last shot - labelled as unidentified, is Eupeodes luniger?

    Plus I have shots I've currently labelled as Syrphus ribesii that are similar to your S. vitripennis - but crikey, how to tell 'em apart is beyond me.

    Nice shots & blog BTW.

  2. Cliff thanks, I'll check those two out again. The Eupeodes looks especially promising. As you say though, many hoverflies are difficult to identiify.

  3. Your penultimate species is Platycheirus manicatus. The Eupeodes is as far as I can see E. luniger. You cannot put a name to the Syrphus species from photos I'm afraid - the important characters are microscropic hairs on the wings, legs and eyes.

    If you want help with ID contact me.
