Moving On
For the past few of weeks, I've been spending most of my free time working on a backyard project that's been going on and off for some time now. It's getting pretty cold lately, so I'm here blogging instead. I usually work on it after a major exam, or when I'm fighting with Tu Anh.... you would think I'd be done by now hehe.... Digging in the dirt gives me an opportunity to relax my mind from the myriad of drugs, treatments, physiological and pathophysiological mechanisms, biochemical reactions, physical examination techniques, arrgghhhh etc...that I need to know. I have been able to contemplate less pressing issues lately, and it feels great. The effect of such contemplation is that I have something to blog about.....

While working outside, I saw many Canada geese fly overhead in their characteristic migrating V pattern. I haven't seen any of them lately, so I suppose winter is very near when the geese have already moved on. But seeing them made me think of another winged creature that migrates south for the winter..... The monarch butterfly, Danaus plexippus. These little things are amazing. Like the geese, they've already moved on to warmer climes, but I recalled flocks of them over the summer. I used to see some gliding by the window from as high up as the 4th floor.
On a recent study break with my study group, we decided to go for a walk in a nearby park. It reminded me of ecological surveys during my undergraduate days, and re-kindled my love of biodiversity, so lets take a brief look at this interesting species..... About one month ago the first monarchs were sited in their wintering grounds in Mexico. There, millions of monarchs will stay, surviving on the energy reserves they built up over the summer until around March. Then they will make the journey north in search of Asclepias plants (wilkweed or butterfly weed). A single female will begin her journey with about 400 eggs. She would have been born in Southern Ontario last August and will only have several weeks to lay her eggs before she dies. Her offspring will be born in Texas or another southern state, and they will continue their mother's journey north. The first monarchs are sighted in Southern Ontario by May. They will search for wilkweed and lay their eggs. The grandchildren of our matriarch will probably complete their grandmother's journey back to Mexico in the fall; 3000 miles away, to a place they have never seen before, guided by instinct alone.
The sex-life of the monarch is no less interesting. When a male spots a female he will dive at her to direct her flight downward to the vegetation. He may even hold on to her body and glide down with her. When she has landed, he will join his abdomen to hers and they will proceed to do the nasty. Still connected in a frenzy of copulatory lust the two may fly up together to as high up as 75 feet. With the female suspended beneath the male, he may fly them up a tree where they will remain joined for as long as an hour. Whew.... kinky....
Pondering the lepidoptera made me think of a charming Native North American legend that I learned of in, of all places, the Philippines. It goes something like this: when the Great Spirit created the butterfly He gave them all the colours of the rainbow but no voice. If you catch a butterfly, tell it your wish and release it. It will keep your wish secret and take it to the Great Spirit, who alone will hear it. I learned of this because, as I've mentioned before, I almost got married in what seems like an eternity ago. Butterfly release during weddings was quite popular then. When I realized that I needed to move on from that relationship, I sent her a box of live butterflies to release on her own. A symbolic "I release you" but "I wish you well". Remembering this reminded me of how lucky I was in not getting married, like the geese and monarchs, I too have moved on and know that I am exactly where I need to be. I was reminded however, of my friends who were there for me during that painful episode, and having been blogging about nostalgia, it made me miss them. So here's to....
Kim (who's catching butterflies with me here)...
Chuck.....
Joy and Steve (and Bambi)....
and Neil....
Cheers guys!
I think I've finally decided to move on from my Friendster blog, so if there are no objections..... I didn't think so...... this will be the last time I post there.
