Fire ants use track pheromones to mark the path from the colony to feeding sites. Trace pheromones are mainly known in insects living in colonies, which mark their paths with low-volatile substances such as higher molecular weight hydrocarbons. Ants in particular often mark the path from a food source to the nest in this way. [77]
Trail pheromones are semiochemicals secreted from the body of an individual to affect the behavior of another individual receiving it. Trail pheromones often serve as a multi purpose chemical secretion that leads members of its own species towards a food source, while representing a territorial mark in the form of an allomone to organisms ...
Wild wedge-capped capuchin monkeys (Cebus olivaceus) self-anoint with millipedes (Orthoporus dorsovittatus).Chemical analysis revealed these millipedes secrete two benzoquinones, compounds known to be potently repellent to insects [6] and the secretions are thought to provide protection against insects, particularly mosquitoes (and the bot flies they transmit) during the rainy season.
A black drongo in a typical anting posture. Anting is a maintenance behavior during which birds rub insects, usually ants, on their feathers and skin.The bird may pick up the insects in its bill and rub them on the body (active anting), or the bird may lie in an area of high density of the insects and perform dust bathing-like movements (passive anting).
Colonies of real army ants always have only one queen, while some other ant species can have several queens. The queen is dichthadiigyne (a blind ant with large gaster) but may sometimes possess vestigial eyes. [5] The queens of army ants are unique in that they do not have wings, have an enlarged gaster size and an extended cylindrical abdomen ...
A cat eating grass – an example of zoopharmacognosy. Zoopharmacognosy is a behaviour in which non-human animals self-medicate by selecting and ingesting or topically applying plants, soils and insects with medicinal properties, to prevent or reduce the harmful effects of pathogens, toxins, and even other animals.
Aphid honeydew can provide an abundant food source for ants (aphids in the genus Tuberolachnus can secrete more honeydew droplets per hour than their body weight) and for some ants, aphids may be their only source of food. In these circumstances, ants may supplement their honeydew intake by preying on the aphids once the aphid populations have ...
These ants are commonly called "crazy ants" because instead of following straight lines, they dash around erratically. They have a broad distribution, including much of the tropics and subtropics , and are also found in buildings in more temperate regions, making them one of the most widespread ant species in the world.
