Ichneumon wasp
After spotting two large green caterpillars half way up the stalks on some of my snapdragons,I thought to myself they look happy enough and didn't seem to be doing any damage to the plants.But then yesterday I saw them again and they seemed to be in the same place,as though they hadn't moved.Looking a bit closer,one appeared dead and one half of it looked deflated.It fell off when I nudged it with a twig and the other one has been in the same position for two days now.I think this is something to do with an Ichneumon wasp I saw last week,and reading up on them I'm certain the two caterpillars were parasitised,just like in 'Alien'. Its nature of course but sometimes the natural world can be a bit creepy...

I love ichneumon wasps. They come in all sorts of shapes and sizes. And so useful too. They save on all that insecticide. In fact, I suppose they are insecticides if you think about the meaning of the word.
Isn't Nature brilliant!!!
Did you post about this wasp at the time? I seem to remember reading about them recently...
So the deflated part has been eaten by the wasp grub/larvae do you think?
Creepy like you say
Did you see them on Springwatch?
Taking caterpillars into underground tunnels and laying an egg in them for their offspring to feed off. Nature's amazing! Who needs sprays to kill bugs?
There's something out there to get all of them if we look after Nature.
The exception that proves the rule is of course the Lily Beetle, but it's our fault it has no predators here - we introduced it, even if unintentionally
Besides, I'm a predator of Lily Beetles

I haven't been watching it no- I don't watch much tv tbh... I was reading about them, but poss I was just flicking through my insect book. I had been trying to identify some bees.
I found this dude hanging out with my caterpillars the other day and thought I was going to witness some predation
In the end it just made a jump at a passing fly and missed. Doesn't seem like a very ergonomical way of catching food...
Ive never seen a lily beetle you know. I watered my neighbours recently and kept an eye out but didn't see one...
How strange - caterpillars don't eat flies
odd behaviour!
I think those are Small Tortoiseshell caterpillars
No, the spider just above them... its not a good photo...
Doh!
If I was I spider I'd be jolly pleased with that photo - quite flattering really!
You mean hunting spiders grabbing flies like this
On the back door frame.
I do believe that's a Zebra Spider you have there fidget
Yes Victoria I think I did post about Ichneumon wasps.There is still one caterpillar there that has been in exactly the same position since at least Tuesday.I'm sure its dead but doesn't appear to have been eaten at all,not like the other one.
Reading about Ichneumon wasps on wiki,there's info about how they parasitise a fellow parasite,the butterfly phengaris rebeli. Its here...

Its really quite incredible
