Not a Monarch

News: Waiting for the Surge
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 to ride the tailwind into the summer breeding grounds.

Population Building
One sign that the new generation is emerging in the south is an increase in the number of butterflies. This Oklahoma report suggests the population is building.

"Finally my first sighting of 2015 today — and it was of four monarchs in the vicinity of Green Antelope Horn milkweed."

Compare Years
The timing of arrival in the northern breeding grounds is important and it can vary from year to year, as the migration maps show. The size of future generations is largely determined by arrival time according to Dr. Chip Taylor. He believes the ideal window is the 10-day period from May 11 - 20. Let's see what happens in the week ahead!

Watch Out for Look-Alikes
Thousands of observers track the monarch's migration every spring. These people expand the eyes and ears of scientists, but proper identification is critical.

Look carefully for the monarch's tell-tale field marks — and try to snap a picture. We review all sightings reported to the migration map and will contact you if we need more information for verification.
