Another of the butterflies which overwinters as an adult, though you are less likely to find it in your shed or house than the Peacock or Small Tortoiseshell as it tends to hibernate in woods. You will find it on the wing from March.
Beginners sometimes wonder if this butterfly is a Fritillary, but the ragged edges of the wings make it easy to differentiate. Males and females are similar.
The upperside of the Comma is bright, so it tends to be easy to spot, especially when flying. When it closes its wings it is very well camouflaged, being quite dark, with the exception of the white mark which gives it its name, and even this helps, by breaking up the solid shape. If seen in strong light, there is actually quite a lot of variation in the brown of the underside, including some greeenish spots.
There is a variation on the ‘normal’ Comma, known as the Hutchinsoni. The eggs laid by the adults which emerge from hibernation in spring become adult butterflies, and these may either go into hibernation, or they may lay eggs themselves and the adults will emerge later in the same year and then go into hibernation: it is these later ones that are called the Hutchinsoni. The ‘decision’ at to whether to produce another brood takes place in the caterpillar stage, and if the adult is ‘normal’ it will be the usual colour, while the Hutchinsoni is more golden, and has less ragged edges to the wing. This ‘decision’ seems to be influenced by day length.
