Butterfly or moth?

One of the first things we learnt on this Earthwatch project was how to tell the difference between a butterfly and a moth as both would by flying along the transects. This proved surprisingly more diffcult than I had thought!

1. Butterflies tend to have clubbed antennae while moths antennae taper to a point
2. Butterflies are able to fold their wings up vertically over their back, where moths often hold their wings horizontally.
3. Butterflies tens to have large, more colourful wings than moths, although many moths are large and colourful also.
4. Butterflies fly during the day, while moths are nocturnal.
