Monarch butterflies have fascinated humans with their vivid black and orange colors. What’s more fascinating is their ability to journey for up to 3ooo miles or 4800 kilometers. Sadly, the population of these remarkable insects is relatively declining.
Based on the Biological Conservation journal’s study, the population of the monarch butterflies from western North America has radically shrunk than previously thought. This species is more prone to be wiped out compared to the eastern monarch butterflies.
According to the associate professor at Washington State University Vancouver and lead author of the study, Cheryl Schultz “Western monarchs are faring worse than their eastern counterparts. In the 1980s, 10 million monarchs spent the winter in coastal California. Today there are barely 300,000.”
She added that the western monarch butterflies might vanish in the coming eras if measures will not be taken to replenish its population.
Eastern monarch butterflies spend winter in Mexico while western monarch butterflies vegetate near the coast of California’s forests. It lays its eggs on milkweed in spring and feasts on the nectar of the flowers that flourish in Arizona, California, Nevada, Oregon, Washington, Idaho, and Utah. During fall, these beautiful insects revisit their overwintering ground, the Washington State University points out.
