Born to be Wild

Series in which amateur naturalists explain their passions. Britain's green army of wildlife watchers are on the lookout for bugs and the great thing about studying creepy crawlies is that they are found everywhere, from back gardens to country lanes. One bug lover finds delight in 2mm-long snails, one has turned his garden into insect heaven, another risks life and limb by going into a floating bog to find dragonflies and a fourth is striving to bring back the bugs that keep our rivers alive.
