Possibly. I once saw a sphinx moth caterpillar (Smerinthus cerisyi,
Cerisy's sphinx, as I recall) at the Nature Conservancy's Kern River
Preserve (now transferred to Audubon) that had been taken by a large
wasp (the site where the wasp had injected the caterpillar with its
paralysing agent or whatever was visible). The wasp dropped the
caterpillar when an observer working on the preserve's biodiversity came
around the corner of an adjacent building. How great the effect will be,
I suppose, depends on the numbers of wasps and butterflies (and moths and
their caterpillars) present.
