Protecting Butterfly Host Plants: Caterpillar Predators and Organic Control

Wants to kill worms eating dill/parsley (butterfly host plants) without BT. Also has wasps eating caterpillars and red bug carrying them away.

Clarification Needed

Confusing: wants to kill "worms" on host plants but also protect caterpillars from wasps/red bug?

Follow-Up Description

Green inchworm-type
Black-striped with red head
Red bug, 6 black legs, 1/4" body

Recommendation

Contact county Cooperative Extension Master Gardeners (search "[your county] [your state] Master Gardeners"). They can ID pests and advise on butterfly gardening balance.
