Animal Crossing: New Horizons is going to see another change to its wildlife when October ends. There are a lot of critters leaving the Northern Hemisphere. I will tell you what you need to catch for your Museum and Critterpedia before they are gone. And if you are in the Southern Hemisphere, then go check out my guide for that instead.
First I will cover the bugs, then fish, and finally underwater creatures. The bugs that can be found flying around are the Yellow Butterfly, Red Dragonfly, Darner Dragonfly, and Banded Dragonfly. All of these are fairly common and will be easy to catch, as they just fly around randomly.
The Yellow Butterfly will be more common around flowers and spawns from 4am to 7pm. The Red Dragonfly spawns from 8am to 7pm and can be found flying anywhere. The Darner Dragonfly can be found zipping around from 8am to 5pm. All these dragonflies can be caught rather easily as you can catch up with them.
There is one tricky Dragonfly though, and that is the Banded Dragonfly. It’s the fastest dragonfly and the hardest to catch. Banded Dragonflies are easy to identify since they are larger than the others, and noticeably faster. Banded Dragonfly will spawn between 8am and 5pm. There is a trick to catch these fast critters, though. Banded Dragonflies will do three quick bursts of speed in random directions. Try to keep up with the dragonfly and predict where it will go.
After the third burst, the Banded Dragonfly will stop to recover its stamina. This is your time to strike and catch it with ease. Just make sure to move quickly because the Banded Dragonfly only stays still for a few seconds.
Next up are the flower dwelling bugs leaving at the end of October, which are the Stinkbug, Man Faced Stink Bug, and Ladybug. These can all be found on any kind of flower, so start planting if you do not have any.
Stinkbugs are all green and can be found at any time. Man Faced Stink Bugs are orange and black and can only be found between 7pm and 8am. The Ladybug looks like a red dot and can be found from 8am to 5pm.
Last we have the ground dwelling bugs that are leaving, which are the Tiger Beetle, Bell Cricket and Scorpion. The Tiger Beetle will be the easier one to catch since it can be found at any time. As for Bell Crickets, they can be found from 5pm till 8am and are quite common. Bell Crickets also chirp constantly, so you can find one by following the sound it makes.
Scorpions are rare and can only be found between 7pm and 4am. Not only that, but Scorpions are one of the few critters that can knock you out, meaning that if you mess up on catching a Scorpion, you have to hunt for another one.
The best way to hunt for a Scorpion is by going to a Mystery Island after 7pm. Ideally you want a flat island with no rivers, but do not worry if you are having trouble finding one. Once you are on a good island, cut down all the trees, dig up the stumps, and pick all the weeds and flowers. You can dig some holes if you want, because these can be used to trap a Scorpion for an easy catch.
When the island is bare just walk around slowly to look for Scorpions. Eventually one will spawn and you can catch it. To catch it safely ready your net and look at the Scorpion’s stance. If the Scorpion has its pincers in the air, do not move towards it. Once the pincers are down it is safe to approach the Scorpion. Make sure to halt immediately when the Scorpion brings its pincers back up.
Catching Scorpions this way guarantees you will get them every time. Scorpions sell for 8,000 bells, so this is a great bell farming strategy, too!
Now it is time to look at all the fish leaving when October ends, starting with the river fish: the Snapping Turtle, Tilapia, Rainbowfish, Betta, and Angelfish. The Snapping Turtle is slightly rare, with a size 4 shadow. and can only be found between 9pm and 4am.
As for the Tilapia, Betta, and Rainbow Fish, these are more common. The Tilapia has a size 3 shadow, the Betta a size 2 shadow, and the Rainbowfish has a size 1 shadow. All these fish can be found between 9am and 4pm except for the Tilapia which can be found at any time.
Of course I saved the rarest fish for last: the Angelfish. This one has a size 2 shadow and can only be found from 4pm to 9am. It is extremely rare and therefore hard to catch.
The best way to get a hold of this sneaky fish is through Mystery Islands. Bringing fish bait with you can be a big help if you have some laying around. Try to find an island with a river, and just scare away any fish that are not a size 2. This is how I managed to finally catch the elusive Angelfish.
Onto the pond fish! Only one is leaving this month, and it’s the Catfish. This size 4 fish can be found in ponds from 4pm to 9am. The Catfish is very common, so catching one will be a breeze.
Moving onto the ocean fish, the Moray Eel and Ribbon Eel are leaving. Both these eels are easy to distinguish from other fish due to their slender shadows. They also both can spawn at any time, making them easy to catch. The Moray Eel is slightly rarer than the Ribbon Eel, but not so rare that it is impossible to find. Just look for the slender shadows and you will have both in no time!
The last two fish leaving are Giant Trevally and Mahi-Mahi. Both these fish only spawn off piers, have a size 5 shadow, and can be found at any time. Since they are pier fish, they are naturally more difficult to find. I suggest gathering some fish food and going to a Mystery Island. Then throw fish food off the pier where the airplane docks.
Mystery Islands just have better fish spawning overall, and make catching the fish slightly easier.
Finally, we have the deep sea creatures. Only two are leaving in October: the Spotted Garden Eel and Giant Isopod. The Spotted Garden Eel spawns from 4am to 9pm and has a small shadow. It is a common spawn, so it will be easy to get. You can kind of tell when you found one, because it has slow but consistent movement as it runs away from you.
As for the Giant Isopod, this will be more of a challenge. The Giant Isopod has a medium shadow and spawns from 9am-4pm and 9pm-4am. Not only is the Giant Isopod rare, but it is also incredibly fast. So fast that you will never catch it by swimming after it. This makes the Giant Isopod easy to identify, though. Once you have found a shadow you cannot catch, it is probably this critter.
What you will want to do is slowly swim towards the shadow. The shadow will swim away from you, but just follow it and be patient. Eventually you will be able to position yourself directly above the shadow. Then you dive and will catch the Giant Isopod with no problem. Again, if you are having trouble finding this critter then try your luck on Mystery Islands!
There you have it – everything that is leaving the Northern Hemisphere at the end of October in Animal Crossing: New Horizons. I hope this guide has helped you out, and good luck filling out your Critterpedia and Museum. Remember to stay tuned for more Animal Crossing: New Horizons guides!
