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 ...
Hymenoptera is a large order of insects, comprising the sawflies, wasps, bees, and ants. Over 150,000 living species of Hymenoptera have been described, [2] [3] in addition to over 2,000 extinct ones. [4] Many of the species are parasitic. Females typically have a special ovipositor for
The bodies of mature fire ants, like the bodies of all typical mature insects, are divided into three sections: the head, the thorax, and the abdomen, with three pairs of legs and a pair of antennae. Fire ants of those species invasive in the United States can be distinguished from other ants locally present by their copper brown head and ...
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 stingers of the Aculeata (wasps, hornets, bees, and ants) are ovipositors, highly modified and with associated venom glands. They are used to paralyze prey, or as defensive weapons. The penetrating sting plus venom allows the wasp to lay eggs with less risk of injury from the host.
A stinger (or sting) is a sharp organ found in various animals (typically insects and other arthropods) capable of injecting venom, usually by piercing the epidermis of another animal. An insect sting is complicated by its introduction of venom , although not all stings are venomous.
This sounds like a riddle, and in a way, it is. Scientists whose interests in insects and fluid mechanics intersect have been wondering how fire ants stick together in water. When their nests get ...
The little fire ant (Wasmannia auropunctata), also known as the electric ant, is a small (approx 1.5 mm (1 ⁄ 16 in) long), light to golden brown (ginger) social ant native to Central and South America, now spread to parts of Africa (including Gabon and Cameroon), Taiwan, [2] North America, Puerto Rico, [3] Israel, [4] [5] Cuba, St. Croix and six Pacific Island groups (including the ...
