Date and Time:
Tuesday, March 5, 2019 - 10:00
This was an all-day, multi-day event starting March 3, 2019 and ending March 6,2019. During the course of a single day, the numbers were much larger than the 500/hr reported here -- thousands. The flight coincided with the 'super bloom' in the Anza Borrego Desert State Park. The butterflies flew close to the ground (10' to 20') in waves and used the rolling terrain of the desert to float over hills. Did not see them in canyons. Did see them stopped on flowers, but more often in regular streams of flight. Based on our single windshield, mortality must have been great, considering the number of cars/people who had come to see the superbloom.
