Monarch sightings dropped this week, a harbinger of the spring season. Monarchs that eclosed last summer and fall have mostly left the overwintering sites in California and Mexico and are reaching the end of their lives. But Dr. John Dayton reports just a few male monarchs at the overwintering sites still in Santa Cruz, California.
Migration can be stop and go with the variability of spring weather. Watch the weather patterns across North American. Keep reporting your sightings to Journey North.
Warmer temperatures have returned but new sightings of monarchs and their eggs, larvae and pupae are still occurring in California and Arizona in the same regions as last week. This is the time in the spring migration when tracking monarchs becomes more of a challenge.
Something to celebrate. More monarch arrivals!
