The Vermin only teaze and pinch
Their Foes superior by an Inch.
So, Nat'ralists observe, a Flea
Hath smaller Fleas that on him prey,
And these have smaller yet to bite 'em,
And so proceed ad infinitum:
Thus ev'ry Poet, in his Kind
Is bit by him that comes behind.

Wasps are moving in? There goes the neighborhood...

Sounds like the beginning of a Lars Von Trier movie.

Hows about we stop intentionally introducing species into places they don't belong. That seems like a good idea.

This wasn't really a case like that. The butterfly occurs on many surrounding islands. Their population dynamics has been tracked for decades. The islets are small (typically a square mile or so) and can support only small populations, making them sensitive to random extinctions. The species comes and goes quite naturally in the archipelago: new islets get colonised, some populations die out.

So the species is not 'where they don't belong'. These particular islets just happened to be vacant at the time.

/ not involved at the research, but spent some days at one of their cabins.

<p>I very much doubt the claim that the researchers did not know they were also transporting parasitoids. FFS, thge Hanski project was a long-established butterfly ecology research group by that time, with a major research insect in host-parasitoid dynamics.

Claiming they didn't know is a bit like saying Jeremy Clarkson may not know his cars have wheels. Maybe it *is* his particular blind spot, but it doesn't seem particularly likely. :P
