first inkling of this was a few days ago, as I pulled out of the parking lot at
Trader Joe's. I spotted a quickly moving smear of color – orange, black
and white – flying in a choppy arc towards the Santa Clara River.
Ah…the Painted Ladies are back!
Painted Lady
butterflies often migrate north around March or April – heading to Oregon and British
Columbia. But their numbers are usually
smaller. The last time we had a superhighway-sized migration was March of
2005.
Painted Ladies begin their migration in our southwestern deserts and northern Mexico.
When the desert has received sufficient winter rains, plants begin to grow,
providing ample food for the butterfly larvae.
Click here
for an amazing time-lapse video showing how the Painted Lady caterpillar
transforms from a larvae into a butterfly. First, it sheds its skin to
form a pupa and 12-14 days later, emerges from its chrysalis as a butterfly.
Painted Lady
larvae feed on a wide variety of plants, such as lupine and thistles.
When enough Painted Lady butterflies have emerged, they head north.
No one really knows for sure what triggers their migration. Population
pressure, more daylight, warmer temperatures? I like to think it has
something to do with the lure of the open road:
"Green, green, it's green ,
they say
On the far side of the hill
Green, green, I'm going away
To where the grass is greener
still."
