American scientists report that butterflies across the United States are rapidly disappearing. A new study using 76,957 surveys found numbers down by 22% since 2000. Researchers from various institutions tracked samples in the Lower 48 states.
The severe decline is caused by insecticides (chemicals that kill insects), climate change, and loss of natural habitats. They warn that reduced populations seriously affect ecosystems and human well-being by reducing essential pollination services.
Additional details reveal that the study noted 114 species had severe declines while only nine species increased. Butterflies in dry regions are hit hardest. Key findings include:
- Southwest populations fell over 50%.
- The red admiral dropped 44%.
- The American lady lost 58%.
‘Immediate steps are vital to protect these insects,’ experts state.
These facts help guide local actions and future preservation plans. New planned surveys offer hope for saving nature.
In summary, butterfly numbers in America are rapidly falling, urging immediate action to protect nature’s beauty and essential life functions.
