Butterflies Need Help

(Recap of an Associated Press article from Carolyn Henderson)

North America has approximately 650 species of butterflies and all but nine of them are in trouble. Approximately 114 of them are showing significant decline including the Monarch.

Monarchs are reported to be down to 10,000 in 2024 compared to 1.2 million in 1997. The annual report that was just released about Monarchs from another group stated that there were slightly more hectares covered in Mexico, their winter home, than there were last year, but it still isn’t even close to a sustainable number.  They covered approximately 1.8 hectares in 2024 compared to .9 in 2023. Scientist say they must cover at least 6 hectares. One hectare is equivalent to 2.471 acres. 

All butterfly populations are down by 22% since 2000 in the lower 48 states. Their numbers are dropping on average 1.3% every year. There are 96 species that are so sparse, they didn’t show up on any of the counts in 2024. There are another 212 species whose sightings were so insufficient, a trend could not be calculated for them. 

Two that I have seen in Milam County are on the high risk list. The Red Admiral population is down by 44%, and the American Lady population is down by 58%. Monarchs come through this area, too, but in small numbers. They are seen more along and west of I35 when they migrate.

An entomologist that reviewed the collection of butterfly counts said he considered the numbers a sign “telling us the continent’s health is not doing well.” The numbers of parrots and porpoises also are dropping notably. 

Butterflies are pollinators – not as much as bees, but they still contribute significantly. They are a major pollinator of Texas cotton crops – a crop often grown here. The driest and warmest areas, including Texas, are showing the greatest decline. They are doing better in colder climates. 

Butterflies aren’t alone in their decline. Other insects that aren’t studied nearly as much also are thought to be in decline. 

As usual, climate change, habitat loss, and insecticides are faulted. You can help by planting native wildflowers in your yard to help feed all species. Turn over some soil, throw some NATIVE Texas wildflower seeds out there, and create a butterfly garden in your yard. Native plants require very little effort once you get them growing. They need to be native to your area because butterflies need the nutrients provided by what nature normally would provide. 

If you need seeds, go to the Cameron Public Library where Texas Master Naturalist – El Camino Real chapter is giving them away. At the library, you also have access to plenty of information from the Lady Bird Johnson Wildflower Center if you have a smart phone. To see these wildflowers in full bloom, wait a month or so, and come to the ECRTMN Wildscape out on CR 334. Announcements will be made when lots of them are in bloom.
