There was either a moth larvae or perhaps even saw fly larvae (not seen) but had been present munching away of all plants a zygo cactus or christmas cactus thou I think this one flowers in november, the droppings were scattered around the cactus and was active for a while something I,ve never witnessed with cacti before, the droppings looked similar to ones from around basil plants I had growing Indoors this summer and also traces of silk (cocoon) in basil leaves and cacti Infact I did trace the larvae from the basil plants which were chewing away the leaves luckily ones passed their prime to eat, I would be greatful if perhaps someone could throw some light on to this subject for me.
