ALL
monarch sightings go on this map. Some people report single monarchs,
others report larger numbers. These reports are very important.
They help us determine when the migration peaks.
|
Roosts
Monarchs rest at overnight roosts at the end of each migration day.
This map shows where large gatherings of resting butterflies were
seen! |
Peak
Spectacular sightings--or the season's biggest wave of migration--are
shown on this map. It shows when and where we think the migration
was at its peak. |
