The ultimate in camouflage
Radio 4 on epigenetics and healthOver at Myrmecos, Alex Wild has published this picture by William Piel and Antonia Monteiro of this amazing moth, Macrocilix maia, which Canada Goose Coats On Sale lives in Malaysia and Borneo. This is a kind of Rorschach test. What do you see?

On his Flickr stream, Allan Lee published another photo and writes: pattern looks like 2 flies approaching some bird dung. As my friend have highlighted, we notice that there a bad smell emitted by this moth. This is really an interesting moth trying to fool it predators by both sight Canada Goose sale and smell. can find other Flickr pictures of M. maia
canada goose outlet washington dc However, there is a much bigger issue here. What is the adaptive value of looking like something else that could be eaten, like a fly? Or even worse, a pair of flies? canada goose coats OK, if the were attacked, then the moth might only get its wings damaged, rather than its body. But that would still be a substantial cost. And surely the added smell would attract either real flies, or predators canada goose clearance on flies It an odd story. As Alex says, this is a PhD Canada Goose Outlet project just crying out for funding, a bold supervisor and uk canada goose an intrepid student. canada goose outlet washington dc

[EDIT 2: Antonia Monteiro mailed me, giving me permission to reproduce the photo and saying: this moth cheap canada goose uk is quite extraordinary. This one is particularily thinking there is some interaction with the canada goose outlet environment going on and I don mean the natural selection/mutation type of interaction I talking some type of gene exchange or something between plants and insects and other insects.
Leaf and stick insects are extremely Canada Goose Parka good at mimicry. Too good, imho.
canada goose jacket outlet sale Anyone ever looked into retroviruses and horizontal gene transfer between plants and insects?Knowing what kind of predators are around would probably help tremendously. It seems odd for a tasty insect to mimic a tasty insect, but we thinking in terms of a resemblance to houseflies. As James C, Trager said, these could resemble parasitic flies, or as Lou Jost said, beetles with nasty defenses. canada goose jacket outlet sale
The main predator of such moths might not be birds, but perhaps mantids or reptiles. My understanding is that mantids hunt by movement, so these don seem likely, not to mention that the smell wouldn have much effect. uk canada goose outlet Would the geckos or anoles in the area avoid bird shit and/or the flies that eat it?
canada goose outlet phone number Also, what are the chances that buy canada goose jacket cheap this species seeks bird shit itself, and this is a sexual display? Try not to Canada Goose online think of this tonight when getting frisky with the significant other detail is fantastic, though I love the which are almost perfectly situated, but the legs are still being refined. canada goose outlet phone number
canada goose outlet boston I think this canada goose factory sale is a total coincidence and another example of our own pattern seeking tendencies. canada goose outlet boston
canada https://www.gooseyou.com goose factory outlet toronto location Let remember that what may look like flies to us can represent a completely different cheap Canada Goose pattern to the potential predators of this moth. The sensitivity to the electromagnetic spectrum and the structure of the eye is so different between us and most other species that we can only make a poor guess as to what canada goose clearance sale they actually see. Some of them can UV and polarized light, or miss huge portions of our visible spectrum. Not to mention subtleties like depth perception and binocular vision. canada goose factory outlet toronto location
So there probably no purpose, no reason, no rationale. Just another eye catching accident of nature.
canada goose parka uk It is not essential that there be some evolutionary advantage to that pattern. canada goose parka uk
canada goose outlet trillium parka black The pattern gets exposed to the agents of natural selection in every single generation, and we can surmise that its presence is either advantageous (relative to recently mutated alternatives) or near neutral canadian goose jacket with regard to fitness and therefore canada goose uk outlet to selection. In the latter case there would be nothing maintaining the pattern, and mutation ought to be able to disrupt it without check. canada goose outlet trillium parka black
canada goose outlet seattle I think we can conclude that there almost cetrtainbly is an evolutionary advantage to the pattern. canada goose outlet seattle
Reading all of these supposedly scientists comments, I am totally at lost. (Indeed it must be a PhD material).
I wonder what the odor was like? Did it smell like ordure? If it did that would clinch it for me: attract flies, let the predators eat the real flies.
