Where are the monarchs? Texas should be in peak migration but so far the show is slow. We're waiting to see if the monarchs from the east appear there soon! The new IMAX film Flight of the Butterflies is a must-see. Mexican President Calderón endorses the film and explains the importance of monarch conservation.

Where are the monarchs?
Texas is the gateway to Mexico for migrating monarchs. Most years it's the best place to be. However, these sample sightings convey the flavor of this year's passage. Some people are seeing the migration, but others are not:

"This fall season, I have only seen 3 monarchs. My husband and I have spent every day for the past week sitting out in our backyard looking up." 9/16/12: Mary Kennedy, Fair Oaks Rance, TX.

"They're here! I think the rain caused a fallout. I watched this afternoon and the clusters have just kept growing." 9/15/12: Carol Cullar, Eagle Pass, TX.

"Today was the biggest Monarch flight day of the fall here so far, a constant light stream for several hours of passage.  I'd say I saw at least 500 Monarch marching southbound.  I spotted some up a thousand feet, and higher, at the limit of binocular spotting." 9/15/12: Mitch Heidel, Utopia, TX

Watch the Texas coast!
Keep your eye on the migration map. Peak migration should hit the Texas coast soon. Remember all those monarchs coming from the east? Let's see if they appear along the Texas Gulf coast. The timing would be just right according to long-time observer Harlen Aschen's rule-of-thumb:

"Our rule has been that the big flow will start after the first front that passes through on or after October 21st."

Watch for monarchs that are flying in directional flight, resting at overnight roosts, or refueling at flowers in fields, gardens, or roadsides.
