Some are afraid of a swarm of millions of insects, except that they are beautiful butterflies called painted ladies.

They are conquering the skies of Southern California as they head north for migration.

The butterflies live in warmer areas, but migrate in spring and sometimes in autumn.

"The painted female migration is not rare, but has been going on for centuries, and in a few years the numbers are not as pronounced as this year," said lepidopterist Rick Mikula, president of Butterfly Rescue International. 19659017] These painted ladies travel known annually from the deserts of Southern California in the Pacific Northwest.

In California, they usually fly from north to northwest.

"The huge increase this year is due to the rains in California, which help to extend plant life in an otherwise sparse, overwintering environment," Mikula said.

Rain in the deserts where the North American ladies lay their eggs is the reason for the large amount this year.

The heavy rains made the plants thrive and gave plenty of food to the lady's painted caterpillars.

"More host plants mean more caterpillars that will later become more butterflies I was lucky "To be able to experience such massive migrations up close in the last decades," said Mikula.

Painted butterflies can be found on all continents except Antarctica and South America.

"I also experienced massive migrations of snout butterflies in Texas where it was impossible to drive without the wipers on the highways," Mikula said.

Unlike other butterflies, the painted butterflies lack red receptors meaning they are probably red-green-blind.

"The Painted is also known for its annual migration from Britain to Africa, where millions of people are actually being radar-tracked, and the reverse route has been shown to fly from Africa to the north of the Arctic Circle," Mikula said.

To help butterflies like Monarchs, whose populations have declined, experts suggest planting milkweed.
