OMAHA, Neb. (AP) — Students at schools in Nebraska and Iowa are joining others around the nation in planting milkweed plants to help attract monarch butterflies.

About 30 students and 10 adults last week planted milkweed, a plant that provides the only food for newly emerged butterfly larvae, behind St. Margaret Mary School in Omaha, Nebraska.

Another group of students and volunteers also recently dug and planted milkweed at St. Albert School in Council Bluffs, Iowa.

The two schools were among 10 Catholic schools in the Midwest that received grants to start butterfly-friendly gardens from the National Catholic Education Association.
