The larvae are dark green with black heads and jump up on their end when disturbed. Feeding damage appears as chewing and discolouring of last year's foliage. Chemical control is effective at this time. Monitor for the hatching crawlers of Euonymus scale over the coming weeks. Plants near buildings or in locations with warmer microclimates should be monitored first.
Nymphs are pale green in colour.
They feed on the underside of leaves. First feeding damage looks like small, pin-point yellow spots on the upper surface. Crawlers hatch over an extended period of time. Treat once hatch is observed and follow with a second treatment as required. Systemic insecticides are more effective.
