To kill them all?

[Yellowcakestand]

Collected butterfly eggs and caterpillars hatched. 3 have turned into chrysalis. Out of the other 55, today 7 of them have had parasitic wasp larvae eat their way out of them!!!
Reading up on it, around 70% caterpillars are infected.
Do I get rid of the lot and put them out of their misery of bring eaten from the inside out, or keep and hope that not all of them have it?
I must admit, it was very interesting, also slightly sickening, to watch and read up on!

Boak - but I think I would be inclined to let nature take its course. I hate wasps, but it isn't really for me to say in a wider sense that they have less right to exist than butterflies. Especially as I'm definitely one of life's wasps, not one of life's butterflies.

Just watched that video, so grim! I never heard of this before. Is this a British caterpillar or are you somewhere more exotic? I think I would let nature take its course on this one, as horrible as nature can be sometimes.

I'm in the kill them quickly with fire group.

FFS don't kill them. Let your imagination run free: in how many ways could you use them to get revenge on people who have pissed you off?
I can think of several.

I've got up this morning and there were 2 more zombies. I've taken them outside with the others. 1 more cocoon though. Wonder what will come out of it? Wasps or butterfly?
Yes in Britain. Just Cabbage Whites
