Question: Where do you think the monarchs that are flying in the Central Flyway in Texas came from? Answer: Let's watch the animated migration map and see what it suggests. (We'll have some direct evidence later, when we find out where the tagged butterfly that was dicovered in the Central Flyway in Texas came from!)

More About the Texas Flyways | ||
Dr. Bill Calvert and other monarch scientists think the two flyways in Texas occur because the monarchs come from different places. The timing of the migration is a clue about where the butterflies originated. The monarchs move through Texas in two "pulses."
Did You Notice? Our animated map shows overnight roosts only. These are generally large concentrations of butterflies. The map does not show any monarchs on the Coastal Flyway yet. However, Monarchs are already migrating along the coast, as the map of all sightings shows.
