Butterfly migration, flights
Butterfly activity seemed higher than normal yesterday on Figueroa Mountain. There were many dark orange California tortoiseshell (Nymphalis californica) butterflies flitting around, always moving out of the way of the car when they were close to the road. There were also lighter-colored orange butterflies that, when flying in the road, occasionally flew under/into the car.
While walking in the “meadow”, I noticed bright yellow butterflies with a somewhat haphazard flight pattern, and light-orange butterflies flying fast and always in the same direction. I wondered what was at the end of that direction. The significance of this only started dawning on my otherwise occupied mind (flying butterflies are swept to the back because they are not photograph-able), when I was on a trail some miles away from the meadow. The flight in the same direction by the light-colored orange butterflies was possibly part of a migration.
On returning home, I googled for more information and came across Art Shapiro’s butterfly site, and saw that there was a painted lady (Vanessa cardui) migration further north. Since I thought my observations were of importance, I sent in the information that the migration had been observed on Figueroa Mountain. In an e-mail reply to a number of people, he stated that other reports had been received on this 5th day of the migration.
