News: Eggs in the East
Surprise Sighting in New Jersey
She never saw a monarch, but teacher Linda Flynn discovered nearly 50 eggs between May 3rd and 6th:

"I was stunned! Not a single monarch sighting, and my 85 students are watching too!"

Surprise Sighting in Michigan
Have you seen the dot on the map in Michigan? An expert observer reported a monarch in Grand Rapids on May 1st. It's not uncommon at this time of year to see a single 'flier' like this, miles ahead of the migration. However, there could be another explanation.

East Way Ahead
Migration in the east continues to outpace the mid-continent. This pattern raises interesting questions about the origin of monarchs in the east. Will these eastern sightings lead to a new discovery about migration?

Mid-Continent Migration
Very few sightings were reported during the past week. The combination of a small population and cool temperatures continues to impact this spring's migration. The monarch life cycle is slowed by the cold, and last week's temperatures were 3-5˚F cooler than normal. The next generation may be taking longer to develop, especially in northern Texas and beyond.
