Who doesn't like butterflies? London Zoo has a giant caterpillar for visitors to enter filled with the brilliantly coloured aphids, some of which are as big as the palm of a hand.
Watch them fly around and nibble on fruit, and if you're wearing bright colours they might even land on you. The Natural History Museum has a similar experience, but is only open from April to Septsember.
