Should we kill it?

The white cocoons of the parasitic braconid wasps (Hymenoptera) hangs on the back of this tobacco hornworm. It would probably be better to let this one live in order to let the braconid wasps hatch.  I dont want to get into pest management but plant pollen and nectar producing plants attract Braconid Wasps.  So plant flowers for a beautiful garden defense.

Swallowtail Butterfly

Swallowtail caterpillar

Swallowtail caterpillars are beneficial insects; however, if you are a parsley farmer, you may have a different opinion!  Caterpillars forage heavily on their host plants, but they also serve as a food source for songbirds and other wildlife.  After their metamorphosis into butterflies, they become pollinators, which is important because one-third of the world’s cultivated crops depend upon the work of pollinators like butterfly and bees.  In addition, butterflies are beneficial to humans for their aesthetic qualities.  Many species are brightly colored and so capture the attention and marvel of many people.  Just watching the whimsical flight of butterflies is enough to lift the spirits!  - Joseph
