The red wood ant is a large forest ant that builds big, dome-shaped nests of twigs, grass and pine needles. It lives across much of Europe and northern Asia, from Scandinavia and Great Britain to Lake Baikal. It is special because its colonies can be huge and have several queens, and it can spray formic acid from its abdomen to defend itself.1

Kako jo prepoznaš

  • Head and thorax (front body) are red, while the abdomen (rear) is brownish-black.1
  • Usually has dark patches on the head and the upper part of the thorax, though some individuals are more uniformly reddish.1
  • Workers measure 4.5 to 9 mm long and have large mandibles (jaws).1
  • Builds large, conspicuous dome-shaped mounds in woodland clearings.1

Pogosto zamenjujejo z: Closely related wood ants are hard to separate by eye. Under magnification, the amount of hair is a key clue: this species is hairier than Formica polyctena but less hairy than Formica lugubris.1

Kako nevarna je za ljudi?

Nevarnost za ljudi: BlagaKot čebelji pik ali manj. Za ljudi praktično neškodljiva.

Kaj naredi, ko se prestraši?

When threatened, workers spray formic acid from their abdomens and defend the nest by guarding entrances and patrolling nearby areas.1

Če te poškropi

  • Pike umij in ohladi.
  • Če ima poškodovanec težave z dihanjem, otekel obraz ali grlo ali se mu vrti, kot da bo omedlel, gre za nujno stanje zaradi alergije: pokliči številko za klic v sili.

Vedno najprej pokliči številko za klic v sili (112, 000, 911). To so splošna navodila za prvo pomoč, ne zdravniški nasvet. Osnove prve pomoči

Ostani varen

  • Nikoli se ne dotikaj divje živali, je ne lovi in je ne draži, tudi če je majhna in tudi če je videti, kot da spi ali je mrtva.
  • Pusti ji prostor. Če jo srečaš, ostani miren, počasi stopi nazaj in jo pusti, da gre svojo pot.
  • Če te poškropi: ostani miren, ne premikaj se, pokliči številko za klic v sili (112, 000, 911) ali hitro pojdi v bolnišnico. Zapomni si, kako je izgledala, fotografija pomaga.

Ne preži nate. Strup uporablja, da ulovi hrano ali se zaščiti, in se veliko raje skrije. Več o varnosti

Dejstva

1

Formic acid was first extracted in 1671 by the English naturalist John Ray, who distilled a large number of crushed ants of this species.1

2

Wood ants raid the nests of other ants and insects, and some species take captured young back to their own colony as workers.1

3

Some colonies are huge networks of connected nests, and some of these nests can be several metres high and wide.1

4

Wood ants collect resin from conifer trees and use it in their nests for structure, protection and antimicrobial defence.1

5

A large colony may have 100,000 to 400,000 workers and 100 queens.1

6

Forestry uses this species, which is introduced into an area as a form of pest management.1
