io BUTTERFLIES 



chrysalis is of a beautiful bright green colour, 

 and you may sometimes find it fastened to grass 

 blades growing beneath trees in woods.

THE WALL BUTTERFLY (2) 



I think that you must know this butterfly very 

 well indeed by sight, for it is extremely common 

 in all parts of the country. Indeed in May, and 

 again in August, you can hardly walk along a 

 lane, or through a grassy meadow, without seeing 

 it in dozens whenever the sun is shining. It 

 is called the "Wall" butterfly because it is very 

 fond of resting for a moment or two on the top 

 of a roadside wall. But it seems to have very 

 sharp eyes, for if you walk towards the butterfly 

 it is almost sure to fly swiftly away, only to 

 return to the same spot as soon as you have 

 passed by. 



Like that of the " speckled wood," the caterpillar 

 of this butterfly is green in colour, and feeds 

 upon different kinds of grasses. But you can 

 always tell it by the fact that it has three pale 

 lines running along its back instead of one dark 

 brown streak, as well as a rather broader one 

 along each side. The chrysalis is bright apple- 

 green, with a few yellowish-white spots, and 

 you may sometimes find it suspended by its tail 

 from a blade of grass.
