Why do insects get drunk after eating?

Insects can become "drunk" after consuming fermented fruits or nectar that contain alcohol, primarily ethanol. Their small body size means even small amounts of alcohol can have a significant effect on their nervous systems. Additionally, some research suggests that the intoxication may influence their behavior and interactions, possibly impacting mating or foraging activities. This phenomenon highlights the complex relationship between insects and their food sources, particularly in environments where fermentation occurs naturally.
