Diamondback Moths occur worldwide, but populations are sparse in cold climates. Diamondback Moth larvae are relatively small — about one-third of an inch when full grown — compared to other caterpillars found in Brassica vegetable crops, Their rapid 30-day life cycle can cause serious crop damage.
This pest has many generations per year, five to seven in moderately warm climates with an even higher number in (sub)-tropical regions. Diamondback Moth generations can quickly start overlapping, especially in warmer climates, meaning that eggs, larvae, and pupae can all be found in the same field at the same time.
