Monarch Butterfiles were streaming north over Torrey Pines, just south of Del Mar and North of San Diego all morning yesterday, Tuesday, March 15th. What a wonderful sight! Only a few stragglers are around this morning!

In response to a request for more information:

They were often smaller than I would have expected Monarchs to be and reading your information this would suggest painted ladies. I did read that population explosions in Mexico can trigger large northward migrations, and this would fit.
