I've been dragging my feet (and my heart) trying to write an update on the 2014 Monarch Migration--the news is so grim.  You can find all you need to know online.  It is especially important this year that you report any sightings of monarch butterflies (and caterpillars for that matter!). Learner.org is keeping track, so please use this link to make your report:

I read this remarkable sighting from Montebello, Quebec:  "Three months into the migration, our first Monarch has now reached Quebec, a distance of over 2,500 miles from the overwintering region in Mexico.  I saw a big, beautiful female in the milkweed patch in front of the house. I'd been seeing what I hoped were monarchs over the last couple of days but couldn't get close enough to confirm until just now."  6/10/14 Montebollo, Quebec.

From Monarch Watch, posted May 19, Dr. Chip Taylor assessed the chances for this year's [2014] 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  [Journey North] very closely for the next 22 days." May 19, 2014

Here is a link to a recovery plan from Monarch Watch dated May 27, 2014  http://monarchwatch.org/blog/

And here you will read a not very optimistic projection that the Monarch migration well may disappear altogether. Adding to the milkweed problem, more evidence of small-scale logging has been found at the wintering sites:  http://phys.org/news/2014-01-monarch-butterflies-migration.html
