Well maybe I can be the first to start.
Pest: Leaf miners/leaf borers on Aeoniums;
Deformed leaves, dark lines/dots/markings on leaves.
Treatment: spray leaves with rubbing alchohol. This is likely to make the affected parts of the leaves burn, this is normal.
Aftercare: the alchohol is likely to burn the leaves, so keep plants in the shade for a month after treatment.
Ill check to see if I have any pictures of the pest.
