Formica rufa, also known as the southern wood ant or horse ant, is a boreal member of the Formica rufa group of ants, commonly found throughout southern England in both coniferous and broad leaf broken woodland and parkland. They are the largest native ant species of the British isles, workers can measure from 8-10 mm in length. They have large mandibles and like many other higher ant species are able to dispense formic acid from their abdomens as a defence. Formic acid has been collected from a large number of formica rufus ant being crushed up and distilled by John Ray, an English naturalist, in 1671.
A common diet for a wood ant colony is invertebrates found around the nest, particularly aphids harvested from the surrounding trees, although they are voracious scavengers. Nests of these ants are large, conspicuous, dome-shaped edifices, usually situated in woodland clearings, where the sun's rays can reach them. F. rufa is commonly used in forestry and is often introduced into an area as a form of pest management.
F. rufa is highly polygynous and often re-adopts post-nuptial queens from its own mother colony, leading to old, multi gallery nests which may contain well over a hundred egg-producing females. These colonies can often measure several metres in height and diameter. Formica rufa is aggressively territorial, and will often attack and remove other ant species from the area. Nuptial flights take place during the springtime and are often marked by savage battles between neighbouring colonies as territorial boundaries are re-established.
The species can also establish nests using the mechanism of temporary social parasitism, the hosts being species of the Formica fusca group, notably F. fusca and F. lemani, although incipient F. rufa colonies have also been recorded from nests of F. glebaria, F. cunnicularia and similar species including the Lasius genus.

Hello Robi,
achieving good pictures of ants is a difficult task. So, I admire your result.
Even the faint bristles on the ant's head are clearly visible.
Best wishes, Peter

Well done, Robi.
I like the colours (almost monchromatic, bvery good tones), the DOF, the composition,...

Spettacolare macro, impressionante DOF in relazione al rapporto d'ingrandimento, eccellente nitidezza e definizione dei dettagli, molto belli i colori e la luce del flash crea una bella luminosità. Grazie e complòimenti. Ciao Maurizio

Hi Robi,
Excellent ant macro, ultra fine details for one so small.
Very good DOF, color, and exposure.

Bonjour Robi,
Félicitations pour cette image réussie d'une "adorable" petite fourmi. Pas facile de bien les photographier. J'aime beaucoup la petite lueur dans les yeux de l'insecte. Ta notice explicative est aussi excellente. J'ai une fourmilllière près de mon chalet et je crois bien que c'est la même espèce.
Bonne journée et merci aussi de tes gentilles critiques.
A bientôt

Bonjour Robi !
Wow, quel gros-plan impressionnant sur cette fourmi rousse ! On en voit souvent dans les bois, mais elles sont si petites, alors que là on en voit tous les détails, même les petits poils ! :-) J'adore sa pose, debout si fièrement sur sa branche de bois. La composition et le POV sont super, c'est vraiment très réussi. Bravo !!!

Hi Robi

What a wonderful close up view of this ant. I love the POV here, the wonderful colours and the perfect DOF. It is great



Hello Robi!
Very nice capture of so small object! :) I like this close-up a lot.
Anyway, did you know that the term "Formica rufa" includes (in broader sense of course) not 1 but 4 different species? They are really difficult to recognize :)
All the best from Poland,
