What's eating my graptosedum 'vera higgins'?

Graptosedum 'Vera Higgins' is a bronze-pink trailing succulent hybrid of Graptopetalum and Sedum. Mealybugs are the dominant pest threat, colonising the fleshy leaf axils. Root mealybugs can build up unnoticed below the soil line. Occasional aphid clusters appear on new growth in spring. Good air circulation deters most infestations.

White cottony clusters at leaf bases; sticky honeydew and yellowing foliage Dab with alcohol; spray whole plant with diluted neem oil; repeat weekly until clear

Unexplained wilting and colour loss; white powdery insects found on roots at repotting Unpot, rinse and treat roots with neem drench; repot into clean, gritty, fresh compost

Soft-bodied insects clustered on succulent new shoot tips; sticky honeydew deposits Knock off with water spray; apply insecticidal soap; inspect new growth regularly in spring
