Of tiny caterpillars, about a centimeter in length... I didn't notice them until I
put this photo up on the screen and there they were! I discovered they were on nearly
all the potted cuttings of zonal pelargoniums I had sitting on the racks, so I went
over every bud and removed each stem, but didn't kill the caterpillars in case they
belonged to the "good" guys e.g., predatory wasps. If Christine sees this she may
recognise them as being similar to some she has seen? Anyone else got any ideas - I
don't want to spray any insecticides as I have such a good ecosystem going here.
