Monarchs – Premigration Migration

monarch-dsc04501In  a recent newsletter written by Chip Taylor, he mentioned a phenomenon that is new to me. He called it the “Premigration Migration.”

In Missouri, the Monarchs have been quite scarce during the early part of the year, but in the last month or so they seem to be everywhere. Chip reports that Missouri seems to be one of the states where reproductive Monarchs seems to have flown south and have been laying lots of eggs. As a result, I have seen numerous Monarchs flying around and laying eggs in my yard. I reported seeing seven Monarchs a couple of weeks ago and an acquaintance mentioned that she had seen twenty-five. I also noticed twenty Monarch caterpillars in a brand new butterfly garden at one of our city parks. I’ve never seen so many caterpillars at one time.

Two days ago, I counted twenty Monarchs in my yard and assumed the migration was going through Missouri, but now after reading Chip’s newsletter, I think it’s more likely the “Premigration Migration.”

It looks like Missouri is definitely helping the Monarch population during this last month before the real migration.

    This is great news!!! We have been sad here in SW Florida as we hardly seeing any monarchs when we normally are full of new cats and pretty wings.

    MODOT mowers are destroying milkweed and wildflowers in bloom along 370 and I-70 right now. The organizations says it is getting rid of noxious weeds. But since they are mowing with Johnson grass seedheads well formed, the organization appears to be promoting Johnson grass.

    For several years we have looked forward to this pre-migration phenomenon. After planting a Monarch Waystation in a public park in 2014 I was shocked to see so many monarchs laying eggs on the milkweed in late Aug/early Sept. I made inquiry about this and was advised research and citizen science had led to the conclusion that some monarchs head partway south and then lay eggs in Missouri to produce the actual migrating generation!
