What's the difference between a moth and a butterfly?
The moth is closely related to the butterfly and hence they share many attributes but the most consistent difference is that nearly all moths have a hook-like structure joining the hindwing to the forewing.
Most of the myths associated with moths, such as they only fly at night etc, are not reliable indicators as to whether it is a butterfly or moth.
See the Butterfly Conservation website for more information.
How many species of moth are there in Britain?
There are about 2,500 species of moth in Britain, compared with only 70 species of butterfly. They are split into two groups depending roughly on size.
The larger moths are in the macro-moth group and the smaller ones are in the micro-moth group.
This is a very rough division as some of the micro-moths are actually larger than some macro-moths!
