Diamondback Moth
Plutella xylostella (Linnaeus)

Larvae are pale green and grow to 8 to 10 mm in length. Larvae hang/drop by a silk thread when disturbed and wriggle vigorously. They have light, raised spots on the body, and each spot has a distinct stiff black hair growing from it. Small larvae first feed on leaves but move to buds, flowers, and pods as they mature. Moths are small and light-brown. Light areas on the wings form diamond shapes when the wings are at rest over the body.
