News: Signs of Change
Shorter days and changing temperatures are about to trigger migration. The first signs that the journey south is underway are expected any day.

Emerging in Diapause
Monarchs change dramatically at this time of year, in physiology and in behavior. Adults are in diapause when they emerge from the chrysalis. They are full grown — but not reproductively mature. Their reproductive development will be on pause until February. These monarchs will not begin to mate until next spring in Mexico.

Becoming Migratory
Watch for signs of migratory monarchs:

  • flying in directional flight
  • roosting in clusters overnight
  • nectaring intensely

  • Are these early migrants coming down from the north and breeding or...
  • Have monarchs been present all summer but not in numbers large enough to detect?

If the monarchs originated in the north, their offspring are likely the 5th generation of the year.
