💨 Abstract

A study released in March 2022 reveals a 22% decline in butterfly abundance across 554 species in the continental US between 2000 and 2020. The average annual drop was 1.3%, except for the Pacific Northwest, where a 10% increase was observed. However, this increase was mainly due to the California tortoiseshell butterfly's population boom, not expected to be sustained.
