Class: Insecta; Order: Hymenoptera; Family: Formicidae; Genus: Formica; Species: Formica rufa

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 much of Europe[ in both coniferous and broad-leaf broken woodland and parkland. Workers can measure 8–10 mm in length. They have large mandibles and like many other ant species they are able to dispense formic acid from their abdomens as a defence. Formic acid was first extracted in 1671 by the English naturalist John Ray by distilling a large number of crushed ants of this species. 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. rufais 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.

Klasse: Insekten; Ordnung: Hautflügler; Familie: Ameisen; Gattung: Waldameisen; Art: Rote Waldameise

Die Rote Waldameise (Formica rufa) gehört zur Gattung der Waldameisen (Formica), in der Unterfamilie der Schuppenameisen (Formicinae).
Merkmale:
Kopf, Mesosoma und Stielchenglied sind überwiegend rot gefärbt. Die Gaster und die Oberseite des Kopfes sind schwarz. Wangen und Kopfschild sind schwarzbraun, wie auch die Beine, die nur an den Gelenken eine rötliche Färbung aufweisen. Die zwei deutlichen schwarzen Flecken auf Pronotum und Mesonotum sind unscharf umgrenzt. Die Rote Waldameise ist an der Unterseite des Kopfes und am Pronotum viel deutlicher behaart als die Kahlrückige Waldameise (Formica polyctena), mit der sie sehr leicht zu verwechseln ist. So trägt sie am Pronotum mindestens 30 Borsten und an der Kopfunterseite mindestens zehn lange Haare. Das Stielchenglied ist seitlich behaart. Die Körperlängen betragen bei der Königin neun bis elf Millimeter, den Arbeiterinnen 4,5 bis neun Millimeter und den Männchen neun bis elf Millimeter. Die Geschlechtstiere dieser Art schwärmen zwischen Mai und Juni, also etwas später als die von Formica polyctena. Die Rote Waldameise zeichnet sich durch ihre kräftigen Mundwerkzeuge aus. Im Angriffsverhalten beißen die Waldameisen ihren Feind und spritzen Säure in die Wunde. Sie können selbst größere Tiere – wie beispielsweise eine tote Maus – gemeinsam zu ihrem Nest schleppen.

Hello Helmut,
This sad sight of a dead nestling is put to life by the activity of these Wood Ants looking for pickings to take to their nest.
The clarity and natural colours are great where in focus, which makes this also not only a nice capture of these ants as a species but a fine record of the process of nature.
Thanks and enjoy your weekend,
Ivan

Hi,
Nothing goes to waste in nature, its cycle of life and you have captured it well. Though I am sad about the fate of the chick then the ants are benefited. tfs.
