parks, along the outskirts of woods, or on the green turf of meadows, 

 is the first joy and the first passion of children in the country. 



The caterpillar (Fig. 145) is of a yellowish green, or rather greenish 

 yellow, with three yellow longitudinal stripes separated by little black 

 points, from each of which springs a whitish hair. 

 It lives in groups on the cabbages in gardens, and 

 on many other Cruciferae. It is so voracious that it 

 consumes in a day more than double its own weight, 

 and, as it multiplies very quickly, commits great 

 ravages in the vegetable garden. Its pupa (Fig. 145) 

 is of an ashy white, spotted with black and yellow. 



The Pieris rapa, or Small White Butterfly, differs 

 but little from the preceding except in size. The 

 caterpillar, which lives on the cabbage, turnip, 

 mignonette, nasturtium, &c., is green, with three 

 yellow lines. It does not do these much harm. 

 In France it is called le ver du caeur (the heart- 

 worm), because it penetrates in between leaves 

 pressed closely together. 



The Pieris napi (Fig. 146), the Green-veined 

 White, is very like the two preceding, but the wings, 

 the lower one especially, have underneath broad 

 veins, or bands, of a greenish colour. The Pieris 

 callidice, the wings of which are white spotted 

 black, is common in the Alps of France, in Savoy 

 and Switzerland, and in the Pyrenees. Its caterpillar lives near the 

 regions of perpetual snow, on small cruciferous plants. 



The Orange-tips have, in the males, the extremity of the upper

wings of a beautiful orange yellow. The rest of the wings is white in 

 the only British species (Fig. 147), which is to be seen in meadows
