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 ...
For humans, this is a painful sting, a sensation similar to what one feels when burned by fire (hence the name), and the after-effects of the sting can be deadly to sensitive people. [7] Fire ants are more aggressive than most native species, so have pushed many species away from their local habitat.
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
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.
[26] [27] Fruit trees harboring weaver ants produce higher quality fruits, show less leaf damage by herbivores, and require fewer applications of synthetic pesticides. [27] [28] They do on the other hand protect the scale insects which they 'milk' for honeydew. In several cases the use of weaver ants has nonetheless been shown to be more ...
The latest curiosity is a video that surfaced on YouTube showing a phone placed on the ground where a group of ants is moving randomly. When the phone receives an incoming call, the ants start ...
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 ...
Formicine ants have a single node-like or scale-like petiole (postpetiole entirely lacking) and the apex of the abdomen has a circular or U-shaped opening (the acidopore), usually fringed with hairs. A functional sting is absent, and defense is provided by the ejection of formic acid through the acidopore.
