Bill Oddie visits a bog in Dorset. At first glance it doesn't look very exciting, but if you get down low you begin to see a completely different world that contains all sorts of interesting life forms. All the insects that come here are looking for food. Ironically many of them will end up as food themselves. Bill finds a carpet of pink plants - these are carnivorous plants called sundews and they eat insects. On the end of each spike is a tiny drop of liquid that looks like dew, but is a honey-nectar type stuff and irresistible to insects. They fly in and then discover too late that it is as sticky as glue. The plant take several days to absorb and digest the insect. All around Bill are the victims, including a damselfly and a dragonfly he was hoping to get a close view of - the four-spotted chaser. Should he let them go? It is sort of against natural history film-making ethics to interfere with nature. On the other hand there is a little damselfly still alive right in front of him. He frees it and it flies away.
