Cabbage Looper Moth

This is a very common garden pest species found on cabbage and other plants. In a way, it's the moth counterpart of the cabbage butterfly. The cabbage looper, or Trichoplusia ni, is common in Eurasia and North America. The adult moth is migratory, moving across large distances when the population expands. The caterpillar is green and chubby and can be found in the crowns of broccoli and in the inner leaves of cabbage. If you find them, pick them off. Pesticides don't work well with species like this.
