Birds: Birds are a major predator of caterpillars, especially during the nesting season when they need to feed their chicks. They include:
* Robins
* Bluebirds
* Chickadees
* Warblers
* Crows
Insects: Several insects prey on caterpillars, including:
* Praying Mantises
* Wasps (including parasitic wasps)
* Ladybugs (they eat aphids, which are closely related to caterpillars)
* Ground Beetles
* Lacewings
Other animals: Some mammals and reptiles also enjoy a caterpillar meal:
* Squirrels
* Opossums
* Lizards (especially chameleons)
* Toads
* Frogs
Parasites: Caterpillars can also be attacked by internal parasites, such as:
* Tachinid flies (lay eggs on the caterpillar)
* Braconid wasps (lay eggs inside the caterpillar)
Important note: Not all caterpillars are bad for the environment! Some caterpillars, like the Monarch caterpillar, are vital for the ecosystem.
It's also important to remember that different caterpillars have different predators based on their size, location, and defenses.
