Index of Subjects Interesting that in the ~400 images of this species across 19 BugGuide pages that I just went through, maybe half those photos of the larva, there were no images of parasitized caterpillars (no small ichneumon wasp pupae visible). But perhaps photographers just don't like taking such photos? With so many larvae together in the same period in such dense numbers in such localized, predictable habitats, you'd expect that some ichneumon or tachinid fly would have a field day and have evolved to specialize in attacking them. Does anyone know if any such parasites are known? (Collect 100 mature caterpillars and see what emerges, presumably in 2014?)
