Rates of visible caterpillar parasitism

This project has accumulated a lot of observations of visibly parasitized caterpillars. Some caterpillar species have hundreds of qualifying observations.

So now that we have this mass of observations, what can we do with them? One simple thing is to get a feel of rates of parasitism among different caterpillar species. Just compare the number of parasitized caterpillars in this project to the total number of caterpillars, species by species.

Here's that math for most-reported caterpillars in the project:

Carolina Sphinx (Manduca sexta)
386 parasitized of 6017 total = 6.4% of caterpillars visibly parasitized

Cecropia Moth (Hyalophora cecropia)
115 of 1690 = 6.8%

Regal Moth (Citheronia regalis)
124 of 767 = 16.2% (yikes!)

Saddleback Caterpillar Moth (Acharia stimulea)
70 of 1952 = 3.6%

Spiny Oak-slug Moth (Euclea delphinii)
51 of 661 = 7.7%

This project used to be called "Bus Passengers: Caterpillar Parasitoids & More." Yet we have seen parasites not only affect lepidopterans in the larval stage, but many other organisms in all stages of life: dragonflies, grasshoppers, and spiders to name just a few. Based on the needs of our members I've decided to widen the scope of this project to include more than just ...more ↓
