What Kind Of Caterpillars Eat Dill Weed?

The parsley worm, also known as the swallowtail caterpillar, is a common pest that feeds on dill plants. It is easy to identify with its bright green color and black stripes. If only a few caterpillars are present, they can be removed by hand. Biological controls, such as Bacillus thuringiensis, are natural predators or parasites that kill pests but are usually not effective.

The parsley worm caterpillars eventually become black swallowtail butterflies, which can strip dill plants of their leaves and consume flowers. They come in different color morphs and can squeak angrily when poked. Cutworms are caterpillars that live in the soil and feed on the stems of young plants, cutting through them at ground level, causing the plant to wilt and die.

Dill plants are rarely bothered by insects, but if the leaves on your dill plant are disappearing, it is likely due to caterpillars. Both parsleyworms and tomato hornworms are known to cause damage to dill plants.

Eastern Black Swallowtail caterpillars, also known as Eastern Black Swallowtails, love to eat dill and rely on members of the Apiaceae or Umbelliferae family, including dill, carrot tops, parsley, fennel, rue, and Queen Anne’s. They resemble monarch caterpillars but are actually some kind of swallowtails.

Black swallowtail larvae, sometimes referred to as eastern black swallowtails, rely on dill as a key host plant. They have evolved together with black monarchs and milkweed, and it is the only food source for the Monarch caterpillars, which thrive on this plant.

In summary, the parsley worm and swallowtail caterpillars are common pests that can be managed by providing host plants for larval caterpillar stages.

Which Butterflies Eat Dill Weed?

Fennel and dill are visually appealing herbs with delicate, feathery fronds that serve as excellent host plants for Swallowtail butterflies.
