"In his blue gardens, men and girls came and went like moths among the whisperings and the champagne and the stars"
In this passage, Nick observes the social interaction between the guests at Gatsby's party. By dissecting each symbolism, I reached a conclusion on the underlying meaning of the passage. The "blue gardens" probably indicates that it was at night when this took place, and the nighttime in the gardens could symbolize mystery and some fantasy at the party. When Nick says, "men and girls", it could also be a reference to how Nick might be sexist in saying that the women at the party are not as sophisticated as the men, so they are considered "girls." Also, the moths can be a reference to how the guests were not substantial creatures. They basically served to just feed on their "food", which in this case was "the whisperings and the champagne and the stars." Nick indirectly is showing how the guests were not "real" people and they just fluttered around to "survive" in the party. The meaning behind this image is actually not pretty or whimsical at all.
