Suicidal defenses by workers are also noted in the Brazilian ant Forelius pusillus, where a small group of ants leaves the security of the nest after sealing the entrance from the outside each evening.
Hos den brasilianske myreart Forelius pusillus har man observeret selvmordsadfærd blandt arbejdermyrer, når en lille gruppe myrer forlader boets sikkerhed, efter at de har forseglet indgangen udefra hver aften.
