AntWeb: September 2012 Archives

Hi there, having been to France recently on a University field course I noticed that there were many aphid guarding/milking ants on Broom bushes. I have a few pictures, I find this interaction fascinating so I'd really like to know what species it is.
If it helps any I was in the Cevennes region of France. I've got pictures, not terribly clear I'm afraid. Do you know of a good Ant ID key on the internet? Even to get it down to Genus level would be most useful.

Hi Lorna,

Thanks for your interest in these interactions. They really are amazing! We contacted an expert on French ants, Christophe Galkowski, to help answer your question. According to him, "ant-aphid interactions are very common in France, many species are concerned, especially in the genus Lasius." He also identified the ants that you found as belonging to the genus Formica and are most likely Formica (Serviformica) fusca. This key may be useful for identifying other ants you collected while in France.

Thanks for your question,
Christophe Galkowski, Ben Rubin, and the AntAsk Team
