As I reported, Andreas Kay, a superb photographer of Ecuadorian biodiversity, died last October at the young age of 56. It was a tragic loss, but he left behind a big legacy: nearly 30,000 unpublished photos of insects and plants from Andean Ecuador. These were inherited by reader Lou Jost, a biologist who inhabits a field station in the Ecuadorian rainforest. Lou has promised to send samples of Andreas’s photos from time to time, so we’ll be able to enjoy them and remember the man.
What I didn’t know until Lou wrote last is that Andreas took videos as well, and very good ones (you can see his YouTube site here). Two days ago Lou sent me one of Andreas’s photos and a link to a video of the insect in the picture. First, the photo with Andreas’s caption:
These moss mimic Stick Insects (Trychopeplus thaumasius?) were filmed at Finca Palmonte near Baños in the cloud forest of Ecuador. During daytime they hang nearly imperceptible between moss covered twigs and only become active at night to feed on leaves. They not only look like moss but even move like waving in the wind.
Can you spot it?
Now look at the video and see how the thing moves erratically. It shows that natural selection for mimicry can operate not just on appearance, but also on behavior. (Sound up).
Also from Andreas:
I can’t help but add Andreas’s post from Facebook (forwarded by Lou) when he knew he was dying of a brain tumor. It always makes me tear up. A naturalist to the end. . .
