Flowers attract butterflies. It’s a fact of nature. But, like humans, butterflies do have their favorites. You learned about attracting spring butterflies in Garden Gate issue 74 from Kathleen Ziemer of Butterfliez of Iowa. Want to keep those butterflies coming year after year? Feed their children. Host plants will provide places for adult butterflies to lay their eggs and feed the caterpillars as soon as they hatch. If you have just one or two spring butterflies visit your flowers this year and they find their preferred host plant, next year you could have dozens.

Did you ever wonder how butterflies know if a plant is good for them to lay their eggs on? They have nerve cells called chemoreceptors on their antennae, feet and legs, similar to the receptors we have in our nose and on our tongue. They let the butterfly know which plants will be good places for them to lay their eggs. After all, the hungry young caterpillars will need to eat as soon as they hatch. And when they’re very young, they really can’t travel far for a meal.

Here are some plants to put on the menu for your winged butterflies, and the visitors they’ll attract.
