Large Blue Butterfly : The Wolf in Ant’s Clothing

The large blue butterfly (Maculinea arion – or Phengaris arion, depending on who you ask) is both beauty and the beast. Beauty because … well, it’s a pretty little butterfly, so what more could you ask for? The beast because it’s also such a master of deception, infiltration and carnivory it could be the antagonist in a sci fi horror movie. A fairly brutal sci fi horror movie at that.

So welcome to the world of a butterfly that is both parasite and predator, combining the tendencies of the cuckoo and the wolf. Oh, and it spends a chunk of its life pretending to be an ant.

Sometimes Nature’s just plain weird … And wonderful, of course.

Here it is, emphasizing the ‘beauty’ part of its nature:

And the underside of its wings are even prettier, if anything:

You’d never guess such a fine-looking creature was the result of such a ferocious backstory …

But before we get to that backstory, a little detour that I nearly mentioned in the podcast but didn’t: you can find the large blue butterfly referred to by two different scientific names around the internet: Maculinea arion and (less often, I think) Phengaris arion. The reason for the lack of consistency is to do with how species get named, how those names get revised and the rules scientists follow in coming to a consensus about what name to use – the kind of stuff that interests me, but maybe not everyone else. What I think is a fun little detail, though, which people might not be aware of, is that there is an actual international organisation that exists to resolve these sorts of disagreements, inconsistencies, and so on. The place you go to get a decision, when you need such a thing, on what the right scientific name for an animal is: The International Commission on Zoological Nomenclature. I love that such a thing exists. And I love that they have an open, unresolved case regarding what exactly the Large Blue Butterfly should be called: Case 3508!
