Adults:
Cabbage aphids are approximately 1/16 inch (2 mm) long, greenish-white
in color, and covered with a grayish wax which gives them an ashen
appearance. Adult cabbage aphids may be winged or wingless. Winged
adults are gray-green with a black body and lack the waxy coating
|

|
Eggs:
The black eggs are very minute (less than 1 mm). In the northeast,
cabbage aphids overwinter in the egg stage which is laid in the crop
residue. |
|
|
Nymphs:
The nymphs are pear shaped and greenish-white in color and later develop
gray waxy bloom. |
