This is a fact. Originally, I like to eat fermented food, and many foods will be scented after fermentation. It is not unusual to be attracted by wine.
In fact, not only butterflies, moths, flower golden tortoises, rhinoceros beetles, armor, bees, ants and other insects like wine-flavored food. Beside the rotten fruit and the sap flowing out, they are often seen greedy.
A popular formula for insect lover to attract insects is the wine.
