MONARCH MIGRATION

In March, Monarch butterflies move through Texas, laying eggs before they die. They search for milkweed to lay their eggs on, as Monarch caterpillars feed exclusively on this plant. Texas serves as a critical stop for Monarchs on their journey north, where they reproduce and contribute to the next generation of butterflies continuing the journey.

Encouragingly, a recent report from Mexico revealed that the Monarch butterfly population nearly doubled in 2025. The number of butterflies wintering in the central Mexican forests grew to occupy 4.42 acres, up from 2.2 acres the previous year. While this indicates a significant increase in forest habitat, the population remains far below the long-term average. Despite this good news, Monarchs still face numerous threats. Climatic variations in their breeding areas and the widespread use of herbicides and insecticides continue to contribute to the loss of milkweed and other nectar plants. Additionally, unchecked illegal logging in Monarch reserves poses a further risk.

Why should we care about Monarchs? They are not just beautiful insects; they are vital pollinators. As they flit from flower to flower, they transfer pollen, which is crucial for the reproduction of many plants, including fruits, vegetables, and flowers. Without pollinators like Monarch butterflies, our ecosystems could suffer, and the availability of many foods we enjoy, such as juicy Texas peaches, would decrease.

 How can you help? You can support Monarch populations by planting native milkweed and nectar plants, which provide essential habitats for them to lay their eggs and refuel during their migration. Milkweed is crucial because it is the only plant on which Monarchs will lay their eggs, and caterpillars exclusively feed on its leaves. Here are a few more ways to help:

1. Plant Native Milkweed: Choose varieties like Antelope Horns, Green Milkweed, and Butterfly Weed, which are well-suited to the Texas climate.

2. Provide Nectar Sources: Include a variety of flowering plants that bloom at different times to ensure a continuous food supply for Monarchs.

3. Avoid Pesticides: Pesticides can harm Monarchs at all life stages, so refrain from using them in your gardens.

By taking these steps, you can play a vital role in supporting Monarch butterfly populations and their habitat.
