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 outside of their species.

Ants communicating through touch. Ant communication in most species involves pheromones, which is a method using chemical trails for other ants or insects to find and follow. [1] However, ants of some species can communicate without using pheromones or chemical trails in general.
A pheromone (from Ancient Greek φέρω (phérō) ' to bear ' and hormone) is a secreted or excreted chemical factor that triggers a social response in members of the same species. Pheromones are chemicals capable of acting like hormones outside the body of the secreting individual, to affect the behavior of the receiving individuals. [1]
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]
Pheromones are released by many social insects to lead the other members of the society to the food source. For example, ants leave a pheromone trail on the ground that can be followed by other ants to lead them to the food source. Alarm calls Alarm calls communicate the threat of a predator.
Pheromones can be used instead of insecticides in orchards. Pest insects are attracted by sex pheromones, allowing farmers to evaluate pest levels, and if need be to provide sufficient pheromone to disrupt mating. Chemical communication in insects is social signalling between insects of the same or different species, using chemicals.
Tail wagging to the right side of the body – the dog feels comfortable and safe. [4] A dog rolls on its back and rubs its shoulders on the ground to display contentment [1]: 199 Dogs are said to exhibit a left-right asymmetry of the tail when interacting with strangers, and will show the opposite right-left motion with people and dogs they know.
The hair on his stomach in front of the penis becomes soaked with urine and gains a dark brown tint. Urine spraying is a variable behaviour. It may consist of simply dribbling a few drops of urine, or, large rhythmic discharges from an erect penis. A stream may be aimed at the mane on the neck, or, a fine mist might be sprayed against the stomach.
