Monarch butterfly tags

Filed under: Insects — bob @ 2:36 pm

Monarch butterflies are on the move heading south on their annual migration. Look closely next time you spot a Monarch and you might see a flash of white against the orange and black pattern of their wings, it very well could be a marked butterfly.

We spotted one last week near Ann Arbor. It was flying and feeding on flowers in the Matthaei Botanical Gardens.

I mentioned in a previous blog how the Monarch population has dwindled. Several groups, professional and amateur alike, are studying Monarchs trying to learn more about their behavior during migration. The butterfly we found was tagged by someone working with a group called Monarch Watch, a conservation education and research organization.

Each ultra-light weight polypropylene wing tag has an identification number and an email address printed on it to report your find.

I’m hoping that we found “our” butterfly after it flew and long and arduous journey from somewhere far away. But it could just as well have been tagged and released that day by someone nearby.

Tags are placed in a specific spot on the butterfly wing to minimize flight interference.

All tagging information is placed in a data base. Monarch Watch contacts both the tagger and the person finding the butterfly with the location of where it was tagged and found and, how far it traveled.

Most of the tagged butterflies in the United States and Canada are found dead. Ours however looked to be a strong flyer.

Reporting tagged butterflies helps researchers learn how Monarchs move across north america to their wintering places in Mexico.

Plant for winter harvest

Filed under: Vegetables — bob @ 8:27 pm

One major task in my garden this week was planting seeds for a winter crop of produce.

I have a small, unheated greenhouse — sometimes called a high tunnel — that I built last year out of salvaged parts. That’s where I sowed my seeds. In our climate, most winters are too harsh for winter crops to survive without some kind of protection.

In years past I’ve harvested winter produce from simple homemade cold frames made from window sash, low plastic covered tunnels and other kinds of structures. The secrete is to make sure the structure gets adequate sunlight and that it is air tight to keep frigid winter drafts from freezing the plants.

I was able to plant the entire floor area of my greenhouse with spinach, winter onions, radishes, beets and a couple of different types of lettuce — all cool weather vegetables. The seeds were left over from my spring crop.

I’ve tried setting out transplants late in the season, they just don’t seem to be as hardy as plants grown from seed in place.

When the really cold weather hits, those plants will hardly grow at all, even when protected inside a structure. By sowing seeds now, the plants will have plenty of time to get to a usable size before they go into hibernation. Once they are established they will become accustomed to the falling temperatures and will be more likely to survive.

Time is running short for those who want to try growing produce for winter harvest.
