The Comma is fairly common in Great Yeldham, though mostly seen as the odd one or two at a time.

Individual males can be seen on the same perch, such as on the side of a sunny hedge, for many days in succession.
There are two broods per year. The overwintered adult females lay eggs in April-May to produce the summer brood which emerges in June-July. This brood in turn lays eggs to produce a second brood which emerge as adults in August to early September.

The darker butterflies are produced when the caterpillars have shorter days, and hibernate as adults. They are seen in the autumn and again in the spring.

The larval foodplants are Hops, nettles or Elm.
