Amazing Larvae

Post by Mark Tutton »

Came across this amazing moth larvae on Twitter that mimics a tree snake as a defensive strategy.
The south American Hemeroplanes is a member of Sphingidae and is capable of expanding its anterior body segments to give it the appearance of a snake, complete with eye patches. This snake mimicry extends even to the point where it will harmlessly strike at potential predators!

The wonder of the world, the beauty and the power, the shapes of things, their colours lights and shades, these I saw. Look ye also while life lasts.

Utterly amazing. But the adult moth isn't all that unusual:

Truly remarkable. How many trillions upon trillions of prototypes must have been gobbled up by predators to fine tune this to such an amazing degree!

utterly amazing. there must some further layer of action to produce these amazing mimicries, not just random mutations being selected by reproductive success.

Our own elephant hawk moth shows the same basic pattern: http://www.ukmoths.org.uk/show.php?id=4183. It has the eyes, the swollen 'head' and the reptilian skin.

Presumably, the prevalence of deadly, venomous snakes in the jungles of Peru makes resembling one a paricularly powerful deterrent, increasing selection pressure towards this design.

I remember you posting a video of a Glanville Fritillary larva apparently lashing out like a tiny snake, the effect emphasised by the red eyes on the caterpillar resembling those of an adder (if only very vaguely).

Thanks Alistair - it's an amazing video.

Mimicry in nature, mimicry (accidental) on the forums - quite coincidentally, Mark Tutton posted the same thing a couple of weeks back :D :
