List of bugs arriving and leaving in September in Animal Crossing: New Horizons 

Animal Crossing: New Horizons sees an exciting update at the beginning of every month. However, the update for September is always especially exciting, since it bids adieu to summer in the game and brings the community closer to the much anticipated fall update.

Animal Crossing islands go through a complete revamp in the month of September, as the entire island transitions from a summer setup to that of fall. Players can witness small changes that indicate the arrival of fall in the game. For instance, they can see the grass slowly transition into a lighter shade of green before taking on the full orange color during fall.

Apart from that, September witnesses a huge change in the bugs and fishes present in Animal Crossing islands. A number of bugs leave the game in September, which are replaced by a different set of bugs.
