Moon Moth, a while back on Netflix I couldn't help but watch
Anacondas: The Hunt for the Blood Orchid. I had a *few* technical issues with the movie.
I also watched Cosmos on Netflix. Neil DeGrasse Tyson showed a picture of Angraecum sesquipedale and said that its
pollen is located at the end of its very long spur.
The moth uses its long proboscis to reach the pollen? So where's the nectar?
Bees direct each other to flower patches by dancing. The better the flower patch, the longer/harder the bee dances.
Humans dance too, but not necessarily to direct each other to flower patches.
I don't think that moths dance to direct each other to flower patches.
What about slugs? Do they dance? They certainly leave mucus trails. Bob happens to find Sarah's mucus trail. Her trail informs him that, if he follows it, then he might be able to find some nice new orchid roots to eat. Is this fact or fiction?
I have an orchid growing on a potted Ficus tree. It's Ficus macrophylla and the orchid is Dendrobium delicatum. Both of them are from Australia. My favorite part is how the orchid's roots are intertwined with the Ficus's aerial roots. They've been together for over a decade now. That's a lot of intertwining!
I don't think that this orchid naturally grows on this Ficus. So the combination is fictional?
There are around 20,000 different species of epiphytic orchids... and a lot more different hybrids. How many different potential hosts are there? I wonder which combination of orchid and host would make me the happiest. If I was a bee, which combination would make me dance the longest/hardest?
If you're interested, here's
a list I made of some hosts that orchids naturally grow on. Orchids grow on a really wide range of hosts.
I think orchids are so diverse because they produce so many seeds. A single seed pod can contain around a million seeds. Each tiny seed is a different combination of traits. The seeds are so small because they don't contain nutrients like regular seeds do. Not being weighed down by nutrients allows the wind to carry the orchid seeds really far. But it means that, in order to germinate, the seeds need to be nourished by the right kind of microscopic fungus.
The fungus takes up residence inside the roots of the orchid. The orchid and its fungus trade different types of nutrients with each other. Plus, the roots provide a pretty cozy place for the fungus if there happens to be a long drought. Clearly it's advantageous for the orchid to help the fungus.
We say, "Don't bite the hand that feeds you". Well yeah. But doesn't that seem like a pretty low standard? We should say something like, "Help the hand that feeds you". Or something better.
Orchids understand that all progress depends on difference. More difference means more progress. Unfortunately, we humans still haven't figured this out. People like to promote diversity but I know for a fact that they don't understand what diversity is good for.
Thanks for sharing your story. I hope your mind will continue to be a good host for orchids!
