What distinctive smell do Odorous ants emit when squished?

The distinctive smell emitted by Odorous ants when they are squished is often described as resembling rotten coconut. This is due to the presence of various chemicals, including 2-alkanones, which are released when these ants are crushed. The odor serves as a defense mechanism, potentially deterring predators and alerting other ants to danger.

In contrast, the other choices represent scents that are not associated with Odorous ants. Fresh lemon, foul fish, and sweet pea do not accurately reflect the unique chemical composition found in the secretions of Odorous ants. This specific characteristic helps in identifying these ants in the environment, making it a key point of knowledge for anyone studying entomology or pest management.
