I think that the wet winter killed off a lot of our overwintering Queen wasps which then in turn have not been around to keep caterpillars in check. It is very different.
I have noticed lots of moths and butterflies in my garden pollinating for me and there has been a late season explosion of ichnid wasps, Potters wasps and other solitary wasps who have been enjoying caterpillar feasts. I would much rather have these guys around than the Common and German wasps.
This is the pupa of the Convovulous Hawk moth that likes munching on Kumara, Convolvulus and all in that family. I have not noticed much damage on my Kumara so left this beauty to do its thing.
