There might be serious damage to young cabbages. However, common cabbage butterflies do not appear occasionally. It appears 4 to 5 times a year and passes over the coldest season as a pupa on plant body, wall, and eaves. When the larva becomes an adult in early spring, it starts to spawn on the backside of leaves of white radish, cabbage, and wild crucifer. Common cabbage butterfly generates repeatedly during fall on white radish and Chinese cabbage. Therefore, you can see all the stages of insect from spring to fall. The damage is worse in spring and less in hot summer and raining season. However, it will again start to harm crops from fall. Common cabbage butterfly lays eggs one by one and the adult is active during the day.
