News: Migration Moves into Upper Midwest
"We may be seeing the first wave," predicted Laura Walter of Iowa's Waverly-Shell Rock High School. Indeed, a sudden explosion of sightings occurred this week as the migration spread across Iowa — and into Minnesota, Wisconsin, Illinois, and Ohio.

Prospects for Recovery
Dr. Chip Taylor is assessing the chances for this year's population to rebound.

"The progression of monarchs northward has been slower than normal due to the cold weather. Monarchs need to arrive north of 40°N in good numbers before the end of May for the population to have any chance of rebounding. If the arrivals are few — or mostly delayed — until the first 10 days of June, the chances that the population will increase this year will be greatly diminished. I'll be watching JN very closely for the next 22 days." May 19, 2014
