The Brimstone is almost always the first butterfly to be seen in the spring. Most butterflies die towards the autumn, and leave eggs behind, which hatch out in the following year, but the Brimstone, and a few others, sleep through the cold winter months and come out in the first warm days of spring and _then_ lay their eggs. The Brimstone comes out first of all, often quite early in February, and so he is the first butterfly that is likely to be noticed in the year. [Illustration: THE CLIFDEN BLUE] Perhaps his coming out at a time when cows began to give more milk, and butter began to be more plentiful, had something to do with his being called "butterfly," but I think that his colour had more to do with it. [Illustration: THE SWALLOW-TAIL BUTTERFLY Almost a paint-box in itself. It will give you blue, red, black and yellow. It is only found in the Cambridgeshire Fens] What lovely colours butterflies are! Have you ever fancied a butterfly paint-box? Let us think of a few common colours, and see how we could fill it. Suppose we wanted a blue? Why we should have a whole family of butterflies "The Blues" to choose from, and we should be just as well off for blacks and browns. For red we could take the beautiful scarlet ribbon of the Red Admiral. "Why is he called Admiral?" you ask. Well, Admiral is the same as Admirable, and his old name was Red Admirable. For purple we should have the Purple Emperor and the Purple Hair-streak--there is no purple quite so glorious as the purple that these have on their wings. For orange, the Orange-tip and the Clouded Yellow. For yellow, the Brimstone and several others. For white, of course, the Whites. Green might bother us a little, but there is one English butterfly, the Green Hair-streak, whose wings are a beautiful green underneath. As he is our only green butterfly I give you his picture. He is the upper butterfly in the first picture and, as you see, quite a little one. [Illustration: THE BLACK PEPPER MOTH Probably quite the blackest Moth we have. They vary very much in colouring though] We must not forget gold and silver. When I was young, I expected to find gold and silver in a really nice paint-box, and I do not suppose young people have changed much since then. Silver we should have no trouble about. There is a big family of butterflies called the Fritillaries, who have wonderful patches and ribbons of silver on their wings. I do not think you will find gold, except perhaps a little gold powder, on any English butterfly, but you will find it on several chrysalises. Indeed, Chrysalis means "the little golden one," and the name was given to these queer spiky things because gold patches were so often seen on them.
