News: First Wave Arrives

Crossing the Border
When twenty-seven sightings were suddenly reported in Texas on March 21st and 22nd, it was clear that the migration's leading edge had arrived.

In her backyard in Eagle Pass, Carol Cullar saw her first monarch as it settled down for the night.

"First remigrant of the spring just showed up at 7:03 this evening. I'm about 200 yards from the International Border across from Piedras Negras, Mexico, on a bluff above the Rio Grande."
March 21, 2014 Carol Cullar Eagle Pass, TX

"At 1pm today I saw a monarch flying past our barn. Around 6pm I saw another flying low back and forth over our field and stopping twice to nectar on small false garlic flowers (Nothoscordum bivalve). Monarchs love to get nectar from false garlic flowers and thankfully they are particularly abundant this year. Unfortunately, due to a cool March, our native milkweed (Asclepias viridis) isn't up yet."

Wind and Migration
Wind is a critical factor during monarch migration. Check out the March 21st map to see wind conditions prior to the monarchs' arrival in Texas. Explore the live map to watch how wind conditions affect monarch migration this spring.
