From the Inland Empire to the beach to the valley: If you've been outside, chances are you've seen swarms of butterflies all over the Southern California region.
Some residents who've spotted them said they've lived in LA their whole lives and have never seen anything like it.
Bug experts say with all the rain, it's giving butterflies more plants to eat and more places to lay their eggs.
"It's beautiful. It's something you don't see every day," Angie Evans, Studio City resident, said as she watched swarms float by in South Weddington Park. "Wow. It's unbelievable."
Social media in the LA area has been peppered with people posting videos of the butterflies, asking where they're all coming from.
Brent Carnar, who used to work for the Natural History Museum, said they're called Painted Ladies, and they fly north from Mexico.
Because of the very wet winter LA saw, there's a lot of vegetation for them to feed on, and females can lay hundreds of eggs on one plant.

"It's kind of new. I haven't seen this many butterflies in the spring before," said resident Adam Harrison.
Carnar says these butterflies have a very short life span -- about 4 weeks.
These swarms will likely continue around the LA area for another two weeks as the butterflies continue heading north, he said.
