Pheromones are used for communication in insects. Which of the following is NOT a form of communication sent through pheromones?

Pheromones are chemical signals released by insects to communicate specific messages such as alarm, trailing, and sex-related cues. Alarm pheromones alert other members of the species to potential danger, while trailing pheromones guide others to a food source or nest. Sex pheromones help in attracting mates, facilitating reproduction.

Color identification, however, is not communicated through pheromones. Instead, color and visual cues play a significant role in insect communication, particularly during mating rituals or species recognition. Thus, stating that color identification is communicated through pheromones is incorrect. This is why the option referring to color identification stands out as not being a method of communication sent through pheromones.
