Cladodes of O.lindheimeri infested at the same time as the O. ficus indica shown in Figure 2 but showing no signs of C. cactorum larvae feeding activity.

Retarded larvae of C. cactorum subsisting on the surface of a O. lindheimeri.cladode. These larvae were of the same age as those shown in Figure 3
