[Syrphidae] Re: Xanthandrus comtus

[Francis Gilbert]

Marvellous photo! and very interesting indeed!

According to the pre-2005 literature that I have found, syrphids have been recorded feeding on a number of things other than from flowers or honeydew: water (Speight 2000), sweat (Bänziger 1996), and from stems and leaves (Katsura K 1996 [Interesting behaviour of Leucozona lucorum]. Hana Abu 2: 12). The last is probably the closest to your observation - Katsura described and photographed Leucozona lucorum feeding from the stems and undersides of leaves of Lugularia fischeri.

Best wishes

Francis

Hi,

I received this photo showing a Xanthandrus comtus consume micro fungi on teasel (Dipsacus fullonum), I presume.

Observation between 5:45 p.m. to 6:35 p.m.

Have you ever seen this way of eating ?

Bibliographical references ?

Other explanations ?

Thank you for your answers.

Best regards.
