Thrips (Thysanoptera), although seldom seen, are 2 to 3 mm long. They suck the juice from plants leaving small white, yellow or purple marks sometimes so numerous that the leaves have a white blast appearance. Sometimes they leave lines of damaged cells on the underside of leaves causing the leaves to curl inwards. This provides a haven for the insects. If the leaves are unfolded the insect or their larvae may be seen. Thrips are the carriers of many plant diseases including viruses.

Control is by systemic insecticides.

Random Bonsai Tip

When a tree has reversed taper or a narrowed 'waistline' above the nebari, you could do an airlayering just above the narrow section; or you could damage the cambium layer by either hammering gently with a mallet or by piercing the bark right into the cambium with a sharp object eg. scissors or an awl. You could also make deep incisions along the grain of the bark, where the healing process will cause scarring which would then thicken the trunk.
