How many different species of British caterpillar are there?
There are over 2,600 species of moths and butterflies in the British Isles. The caterpillars of this large family of insects known as Lepidoptera can vary greatly in size, colour, shape, pattern and behaviour. Even the number, position and type of legs can vary between species and features such as this can help with identification.

Certain species of caterpillars can at times become so prolific that they can cause significant damage to vegetable crops, garden shrubs and trees.
Although in general British caterpillars are not a danger to our health there are some species of hairy caterpillars that can cause unpleasant skin irritation unless care is taken.
