Aye usually the further away I am from a large moth the happier I am but this one was fascinating. So odd to see one animal behaving exactly like another, like seeing a cat with an 8 foot neck grazing on a tree.
Totally different species with absolutely no connection whatsoever, just evolved to make use of the same food sources. A great example of convergent evolution.
Saw a bunch of those in Spain a few years ago. I was fascinated by them, trying to work out what the hell they were. Looked so much like hummingbirds. It's only a lot more recently that I googled and worked out they were a type of moth.
