I found out that Bamboo Islands are bootleg Tarantula Islands

[CowKing]

So I was at my second bamboo island, getting bamboo parts I didn't get on my first trip, when I noticed I got a decent amount of tarantula spawns.
So I thought maybe because the island was pretty flat, tarantulas were more likely to spawn on bamboo islands.
To test my theory out, I axed all the bamboo to see better, got rid of flowers to make sure stink bugs don't spawn, and ran around and sure enough, I got a bunch of tarantula spawns! I also got emperor butterfly spawns too! (They sell for 6k bells, 2k less than tarantulas) and I was able to get a full inventory of tarantulas in about 20-30 minutes!

I think it's a pretty decent tip if you can't get yourself a tarantula island, use a bamboo island instead!

Jeez. I've been to a few bamboo islands. Guess I'll have to give it a go.

Oooh. I'll have to keep this in mind next time I am lucky enough to come across a bamboo island.

Yeah, they spawn everywhere after 7pm, rain or shine!

Aw man, I visited like 2 bamboo islands today. I wish I knew this beforehand, I'm gonna need big bells to move all my buildings

Thanks for sharing this with us though.
