Butterflies released in Finland contained parasitic wasps – with more wasps inside

Introduction of Glanville fritillary leads to emergence of three new species on to Baltic Sea island

When caterpillars of a beautiful butterfly were introduced on to the tiny island of Sottunga in the Åland archipelago, scientists hoped to study how the emerging butterflies would disperse across the landscape.

But researchers did not realise that their introduction of the Glanville fritillary (Melitaea cinxia) led to the emergence of three other species on to the Baltic Sea island, which sprang out of the butterfly like Russian dolls.

Some of the caterpillars contained a parasitic wasp, Hyposoter horticola, which bursts from the caterpillar before it can pupate and become a butterfly.

Living inside some of these small wasps was another even tinier, rarer parasite, a “hyperparasitoid” wasp known as Mesochorus cf. stigmaticus. It kills the parasitic wasp around the same time as the wasp kills the caterpillar, and emerges 10 days later from the caterpillar’s carcass.

...Perhaps most surprisingly, given that small island populations are notoriously vulnerable to extinction, all four species are still surviving on the 27 sq km island 30 years after the original introduction.

A parasite within a parasite within a host?

Sounds like how commies used progressives to take over stuff.

And unintentionally devised by parasite scientists.

What a great metaphor for the current political situation

Stories like this could give scientists a bad name. How long will it be before Fakebook and Tweeter ban it?

I think that may be an old number?

There is at least a BAZILLION in my neighborhood!

That’s what you get for not obeying the prime directive.

“Introduction of Glanville fritillary leads to emergence of three new species on to Baltic Sea island.”

I count only three species: the butterfly (Melitaea cinxia), the first parasitic wasp (Hyposoter horticola), and the smaller wasp within the wasp (Mesochorus cf. stigmaticus). That’s three.

Unless they are counting the emergence of a new human subspecies: scientists who can’t count (Mathematica errona).
