In the study, alcohol, and particularly methanol, increased the males' production and release of chemical sex signals, called pheromones, which made them more attractive to females.

Foraging for resources is an essential process for the daily life of an ant colony, and ants will self-organize using chemical pheromones.

The researchers also place moths in a wind tunnel and release sex pheromones to see if the excited bugs are able to locate the smell.

When elephants release sex pheromones, start randomly tooting or begin rubbing against each other, this is not chaotic or random behavior.

So in the new study, Ryo Taniguchi, a paleontologist at Hokkaido University, and colleagues took a different approach: looking for the organs that detect these pheromones.
