Small White Cabbage Buttertly : 1, female; 2, caterpillar; 3, chrysalis. '• 



The egg is laid singly (not in clusters). 



The caterpillars are green, paler green beneath, and 

 velvety ; and have a yellowish stripe along the back, and 

 a stripe or row of spots of the same colom* along each side. 



The chrysalis is of a pale flesh-brown or greenish colour, 

 freckled with black. 



The fore wings of the butterfly are creamy white, with a 

 slight grey or blackish patch at the tip (this patch not as long 

 nor as regular in shape as in the Large Garden White). The 

 fore wings have also one black spot above in the males, and 

 two in the females. The under side of the fore wings is 

 white, yellow at the tip, and has two black spots both in 

 male and female. 



The hind wings are creamy white above, with a black spot 

 on the front edge; the under side yellow, thickly speckled 

 with black towards the base.

Green-veined White Butterfly. Pieris najn, Linn. 



The eggs of the " Green-veined White," which is known 

 also as the " Eape-seed Butterfly," are laid singly under the 

 leaves of Turnips and Cabbages, and though it is doubtful 

 whether the caterpillars are often injurious to any serious 

 extent, they are noted by Curtis as feeding on Turnip-leaves 

 in 1841, and in the same year as doing much mischief to the 

 hearted Cabbages, by gnawing into the middle of them, like 

 the caterpillar of the Cabbage Moth.
