Overview SJS infested bark has a grey, roughened appearance due to scale insects on limbs and trunk. Infested fruit develop a reddish-purple ring surrounding each spot where a scale settles. Biology Adult scales are round (females) or oval (males), about 1/16 inch in diameter, and greyish with a raised yellow nipple in the center. Immature SJS overwinter on twigs and branches under scale covering. Around Bloom, winged males emerge, seek out female scales, and mate. Tiny, bright yellow nymphs or "crawlers" emerge in mid-late June.
