Trap-jaw ant
Trap-jaw ants are small ants with jaws that snap shut faster than almost anything else in the animal kingdom. They live in tropical places from southern Costa Rica to South America and the Galapagos Islands, and they are one of the most common ants around homes and gardens in southern Brazil.1

Ako ho spoznať
- Its main feature is its dark brown colour.1
- The head is 2.09–3.12 mm long.1
- It has hairs on the first gastral tergum (a plate on the upper back of the abdomen), which stand up partly and are fairly even in length.1
- Seen from the side, the petiolar node (a small segment between the body parts) is dome-shaped.1
- Its mandibles (jaws) can open to about 180°.1
Sila jedu
Jed vychádza cez žihadlo.
Čo robí jeho jed?
Its venom is thought to be mainly protein-based. The sting also releases a mixture of formic acid and protein, which may be highly toxic. In people, a sting usually causes burning at the site that fades within about an hour. Some people have a strong allergic reaction, with red, itchy, swollen patches on the skin and swollen eyelids.1
Aké nebezpečné je pre ľudí?
Nebezpečenstvo pre ľudí: BolestivéMôže to poriadne bolieť, ale skoro nikdy to nie je vážne.Its bites are not severe for humans, but they can cause an allergic reaction. One case described a young girl with a strong reaction that lasted about a week. Such reactions were noted in about 16% of ant bites.1
Čo robí, keď sa bojí?
When its nest is disturbed, many workers make escape jumps, and if one lands on the intruder, workers start stinging it.1
Ak bodne
- Umy a schlaď miesta bodnutia.
- Ak má postihnutý problémy s dýchaním, opuchnutú tvár alebo hrdlo, alebo sa cíti na odpadnutie, ide o alergickú núdzovú situáciu: zavolaj na tiesňovú linku.
Vždy najprv zavolaj na tiesňovú linku (112, 000, 911). Toto sú všeobecné rady prvej pomoci, nie lekárska rada. Základy prvej pomoci
Buď v bezpečí
- Nikdy sa nedotýkaj divého zvieraťa, nechytaj ho ani ho nedráždi, aj keď je malé a aj keď vyzerá, že spí alebo je mŕtve.
- Nechaj mu priestor. Ak nejaké stretneš, zostaň pokojný, pomaly cúvni a nechaj ho ísť svojou cestou.
- Ak ťa bodne: zostaň pokojný, nehýb sa, zavolaj na tiesňovú linku (112, 000, 911) alebo sa rýchlo dostaň do nemocnice. Zapamätaj si, ako vyzeralo, fotka pomôže.
Nejde po tebe. Jed používa na chytanie potravy alebo na obranu a oveľa radšej sa schová. Viac o tom, ako zostať v bezpečí

Fakty
Its jaws can close within about 130 microseconds on average, roughly 2300 times faster than the blink of an eye.1
It can jump more than 20 times its body length in a single jaw-propelled leap.1
Its jaws can exert a peak force of about 300 times its own body weight.1
During an escape jump, it can launch itself about 7 cm off the ground and grab onto nearby plants.1
Its jaws have the second-fastest predatory movement in the animal kingdom, after the dracula ant.1
Its nests are usually small, with fewer than about 200 ants, and neighbouring nests do not fight when they are close together but are aggressive toward each other when more than 10 m apart.1
Lovec mýtov
Mýtus: Trap-jaw ants sting in the same way as bees.
Pravda: They do not have stingers like bees. Their stings are retractable and not barbed, so they can be used again.1
