Butterflies don't eat trees directly! They feed on nectar from flowers, which are found on a variety of plants, including trees.

However, certain trees can be attractive to butterflies because they host the plants that caterpillars, the larval stage of butterflies, feed on.

Here are some examples:

* Milkweed: This plant is essential for Monarch butterflies.

* Willow: Caterpillars of many species, including the Eastern Tiger Swallowtail, feed on willow leaves.

* Oak: Oak trees are host plants for a variety of caterpillars, such as the Luna moth.

* Cherry: Caterpillars of the Cherry Hairstreak butterfly feed on cherry trees.

To attract butterflies to your garden, consider planting a variety of flowering plants that offer nectar as well as trees that host the caterpillars of your local butterfly species.
