What is the name of the chemical released by one animal that affects the behavior of another animal of the same species?

The chemical released by one animal that influences the behavior of another animal of the same species is called a pheromone. Pheromones play a crucial role in communication among members of the same species, particularly in relation to reproductive signals, territorial markings, and social interactions. For example, when a female insect releases pheromones to attract males, it allows for successful mating without the need for visual contact. These chemicals are often detected through specialized receptors and can elicit a wide range of responses, from attracting mates to signaling danger.

In contrast, hormones are internal signals that regulate various physiological processes within the same organism rather than between individuals of the same species. Neurotransmitters are chemicals used for communication between nerve cells within an organism's nervous system. The term "feromone" appears to be a misspelling of pheromone and does not refer to any recognized biological concept.
