Monarchs Migrating Through North TX!

 

This female Monarch spent at least 90 minutes nectaring on my Frostweed and resting on my Oak Tree this morning!

Fall Migration is Underway for Monarchs


I haven’t seen any Monarchs yet in Allen, TX, but my Frostweed is just beginning to bloom. I’m hoping that will attract a few that will be migrating through to Mexico! It’s supposed to be one of their favorite nectaring plants.

Fall Migration is Underway!

Sightings of southbound monarchs, intense nectaring, and the first overnight roosts are being reported.

At this time of year, monarchs change dramatically in physiology and in behavior.Responding to Daylength
Declining day length is the central cue that triggers the monarch’s migratory state. In the northern breeding range photoperiod is falling by 20 minutes this week. This sends the signal that it’s time to go to Mexico.Becoming Migratory
Watch for signs of migratory monarchs:

  • flying in directional flight
  • clustering in overnight roosts
  • nectaring intensely

Emerging in Diapause
Beginning in mid-August in the north, adults are in diapause when they emerge from the chrysalis. They are full grown — but not reproductively mature. Their reproductive development is on pause. These monarchs will not complete development and begin to mate until next spring in Mexico.

Beginning a Long Life
The same hormone deficiency that leads to diapause also leads to increased longevity. Summer monarchs live only 2-6 weeks; migratory monarchs live up to 8 months.

Accumulating Fat
Monarchs are shifting focus now from breeding to intense feeding. They must build body fat to fuel migration and to survive the winter in Mexico.

Welcome!
Fall migration 2016 is underway. Please share your sightings and help tell the story of the monarch’s long journey to Mexico.
