There are over 350,000 known species of beetle and many more that are yet to be identified; over 4,000 species can be found in Britain. In fact, beetles are so diverse that they make up 25% of all the world’s animals species.
Beetle larvae look completely different to the adults. Depending on the species the larvae may feed on leaves, rotten wood, other insects or even dung. The larval stage can last for a long time, for example, in the stag beetle this may be four years.
Eventually the larvae will pupate, emerging in its adult form.
The smallest beetles measure less than 1mm but the goliath beetle from Africa can weigh 100g.
