If you looked closely on the vegetation throughout the display you could see caterpillars happily munching on the leaves.
Cocoons were then collected up and placed in a hatchery were you could see row up row of cocoons waiting to hatch
These ones looked truly alien but I swear there are butterflies in there
and you could also watch some emerging into the light
When they first emerge their wings are scrunched up and it takes a few hours for their wings to fill out
It's an incredible process watching them inflate
and wait to dry out
though some did seem to struggle with the process. This poor thing looked as if it was struggling with it's new found wings. It must be a shock to the system to go to sleep as one thing then wake up with a completely different body!
Apologies for the sudden image switch but some how they work better as portrait.
So there we have it. If you're in London it's well worth the £6 entry fee and is guaranteed to awake the inner wonder in anyone. It's open until 11th September so there is plenty of time to catch it. My recommendation is to go during the week and arrive at 10am before the hoards arrive.
