Tonight, I focused on how nocturnal insects use chemical signals to navigate and communicate in the dark. Since visual cues are limited, these insects rely heavily on pheromones and other chemical messengers.
Moths, for example, release potent sex pheromones that can travel long distances in the night air to attract mates. Fireflies also use chemical signals combined with light for mating rituals.
This reliance on chemistry allows nocturnal insects to thrive in environments where sight is less effective.
In my notes:
“In the dark, chemistry lights the way.”
