I think every single species is active, at least on Oahu.
There’s “B52s” that live outside in dumpster/trash. They’re big enough that if you see one on the ground you immediately think it’s fake. And when they’re flying at night you can’t see them in the air, but you can fucking hear them which is even more terrifying. They’re technically just American cockroaches, but because the island life (especially Waikiki) is pretty much perfect for them, they just keep getting bigger and bigger on the island.
Plus with all the people around, they’re not really scared of humans. These aren’t the roaches in movies that scatter when a light comes on or they see a person. They’re used to us by now.
And with so many people riding scooters…
Getting hit with a giant flying cockroach in the face at 40mph isn’t exactly fun, but it’s definitely memorable.
All the hotels, restaurants, and buildings are infested with the smaller breeds. There’s just nothing to do when conditions are fine for them to live outside all year. Even if you somehow killed every one in your building, more are just going to come in from outside to fill the void.
