Migration enters Texas! The monarch parade began on Sunday and continued all week. What will this latest-ever arrival mean for spring production?
Quote:
It was clear on Sunday that the first migrants had finally reached Texas. People suddenly saw monarchs with torn and faded wings, flying northward, laying eggs, or stopping to drink or rest. The wave of arrival continued all week. Simultaneous sightings of multiple monarchs mean the butterflies were moving en masse.

Late Arrival
This spring's return is the latest we've recorded. The first monarchs typically cross the Rio Grande by March 15. This year's arrival at the end of March makes the migration at least 2 weeks late.

Outlook for Recovery
Although the breeding season is off to a late start, Dr. Chip Taylor remains guardedly optimistic.

Finding Milkweed

Spotlight: Monarch Habitat Projects
High quality habitat is critical for monarchs now. The old generation is dying, and a new generation must grow and survive. On Earth Day, celebrate nature's power of renewal and explore how you can help monarch habitat. The Monarch Joint Venture map shows how people are managing habitat in gardens, agricultural areas, natural areas, and corridors.

No longer their brilliant orange, the monarchs from Mexico are nearing the end of their travels. A new generation will continue the journey north.

The migration's leading edge is approaching latitude 38N. This generation rarely goes any farther. The monarchs that overwintered in Mexico have lived up to 8 months. Their lives are now coming to an end.

As the monarchs from Mexico fade away we're waiting for signs of the next generation. A surge in sightings will occur when the new adult butterflies emerge and migrate northward.

How Many Eggs?
After a single mating, a female can lay eggs throughout her lifetime. Each butterfly lays hundreds of eggs as many as 700 have been counted. Because she dedicates her energies to egg-laying, the female only lives a few weeks during this stage of her life.

Dr. Jim Edson of the University of Arkansas conducted an experiment. He found ...

This has been the quietest week of the season, with very few monarchs being reported. The migration map illustrates the annual 'stall' between generations. Watch the animation to see how little the monarchs have advanced over the last 3 weeks.

Monarchs often arrive in the spring just as milkweed is emerging. People want to know: Will there be enough to feed the hungry caterpillars? A Pennsylvania woman compared milkweed growth to monarch development and made a surprising discovery.

Late-season cold and accompanying north winds appear to be holding the monarchs back. However, the wind will shift to a southerly flow by Thursday, May 14th and blow for at least 4 days. Watch for northbound butterflies riding the tailwind into the summer breeding grounds.

The monarchs are finally here! We saw 2 or 3 (not sure if one was a repeat) late last week. The milkweed is up and big enough to support monarch caterpillars. Now I've just got to pay more attention to what's happening on the milkweed.
