The Bug-Off is a bug catching competition that is held during the Summer in Animal Crossing: City Folk and Animal Crossing: New Leaf. The event takes place in the months of June, July, August and September, because these are the months in which a majority of the large insects appear - such as the Oak Silk Moth and the Birdwing Butterfly. The event runs from 9am until 6pm.
Each entry is rated in points according to size, color, rarity and luster - which makes it easy to determine what insects would be rated high e.g. a Snail would be rated low because it rates low in terms of color, size, rarity and luster, while an Agrias Butterfly would be rated higher because it is colorful, rare, medium sized and beautiful.
During the day of the competition, each time a player gives a bug that achieves a new high score, they receive a gift from Nat. In Animal Crossing: New Leaf, Nat gives the player an item from the Insect Series every time a new high score is met. At the end of the competition, the winner of the Bug-Off receives a mention on the Bulletin Board as well as a trophy through the mail. Animal Crossing: New Leaf winners stand on a podium at the end of the competition.
The Bug-Off is the counterpart to the Fishing Tourney, which runs during the other eight months of the year. Unfortunately, the largest fish come out during the summer, so a keen fisher must keep their fish in their home until October to gain an advantage for the Autumn competition. However, the Bug-Off is different from the Fishing Tourney, due to there being only one type of competition - bugs are caught according the color, rarity, luster and size - nothing else, unlike the Tourney, which has two competitions - size and type.
- There are no trophies for second place in all games except for Animal Crossing: New Leaf which has one for first, second, and third place.
- Handing over the same insect twice does not produce the same results, meaning the same insect may be able to overwrite an already existing entry.
- During the Bug-Off, Tom Nook will announce on the tannoy 'Your attention please, today is the bug off, try to get lots of good ones, thank you'.
- In Animal Crossing: New Leaf, if the player is not present when the Bug-Off ends, the award ceremony will be cancelled, and an envelope with the bug trophy in it will come in on the next day if you scored in 3rd, 2nd, or 1st place.
