In flight there is a passing similarity to the Comma butterfly. However, the Fritillary glides and soars. It will also fly along pathways at low level in a mating dance.
Both are shown here.
The Comma is so named because of the white mark on its wing which resembles the punctuation mark. It has an interesting lifecycle in that when its wings are closed closed it looks just like a dead leaf. In that state it will attach itself to a twig and pass the winter in hibernation.
