Multiply the Monarchs

Known for its incredible ability to migrate hundreds of miles, the Monarch butterfly, Danaus plexippus, has suffered from population decline in recent years. As of last year, the U.S. Fish & Wildlife Services estimated that the Monarch population had plummeted by 90% over the previous 20 years. Studies seem to indicate populations increased some last year, but there is still a great deal of work to be done if this species is to be preserved.

Monarch butterflies lay their eggs only on milkweed plants. Monarchs cannot survive without milkweed; their caterpillars only eat milkweed plants (Asclepias spp.). They search for patches of milkweed, which can grow as far north as southern Canada. With shifting land management practices, we have lost much of the milkweed from the landscape, leaving them with a limited food supply. Scientists believe this to be one of the causes of the population decreases.

This year, the Spring Plant Sale at Heard Natural Science Museum & Wildlife Sanctuary will feature a selection of native milkweed plants. By purchasing and planting milkweed to help feed Monarch butterfly caterpillars, North Texans will be able to help the recovery of this species and support the Heard, a private 501(c)(3)nonprofit organization. This sale will also feature native flowering plants that provide nectar for the adult butterflies.
