These ants have a two-segmented petiole (a petiole and postpetiole) connecting their abdomen to the thorax. They have 10 segments in their antennae, which end in large segmented clubs. Thief ants possess small stingers on their oblong abdomens. Worker ants have large jaws for carrying food, usually other ants' brood, back to the colony.
In the case of fire ants, the venom consists mainly of alkaloid (>95%) and protein (<1%) components. [2] Stinging ants cause a cutaneous condition that is different from that caused by biting venomous ants. Particularly painful are stings from fire ants, although the bullet ant's sting is considered by some to be the most painful insect sting.
The pavement ant is dark brown to blackish, and 2.5–4 millimeters (0.10–0.16 in) long. A colony is composed of workers, alates, and a queen. Workers do have a small stinger, which can cause mild discomfort in humans but is essentially harmless. Alates, or new queen ants and drones, have wings, and are at least twice as large as the workers ...
Like all ants, they can also make use of visual landmarks when available [134] as well as olfactory and tactile cues to navigate. [135] [136] Some species of ant are able to use the Earth's magnetic field for navigation. [137] The compound eyes of ants have specialised cells that detect polarised light from the Sun, which is used to determine ...
Meat ants are able to kill poisonous cane toads, an introduced pest, as the toxins exuded by the toad, usually lethal against its predators, do not affect the meat ants. [138] Due to this, scientists in Australia have considered using meat ants as a form of pest control to reduce the cane toad population. [ 139 ]
“Ants have palates, and if they don’t take the bait immediately, you’ll need to try a different formula,” says Suiter. “It’s not like they’re going to change their minds.”
Fire ants sting and bite, particularly little kids since they can come into contact with dirt mounds playing outside. During those rare summer showers, fire ants will immediately turn up.
[227] [228] Unlike in honeybees, the sting lacks barbs, and so the stinger is not left in the area the ant has stung, allowing the ants to sting repeatedly without any harm to themselves. [229] The retractable sting is located in their abdomen, attached to a single venom gland connected by the venom sac, which is where the venom is accumulated.
