An Undergraduate Entomology Class Investigates the Insect Life Lost with Autumn Cleanup

Over the last decade, a growing body of research has highlighted significant declines in insect abundance, bringing insect conservation to the forefront. While patterns vary across geographic regions and taxonomic groups, many studies show sharp declines in the abundance and biomass of many insects over the last 30 to 50 years, often at rates exceeding those of vertebrates (Dirzo et al. 2014, Forister et al. 2019, Wagner 2020). Numerous factors contribute to the current insect loss, including widespread use of pesticides and stresses associated with climate change. However, the leading driver of their decline is habitat loss through agriculture and industrial, urban, and suburban development (Dirzo et al. 2014, Schwägerl 2016, Forister et al. 2019, Wagner 2020). Given the urgency of addressing global insect decline, it is important for citizens to engage in conservation efforts. To foster meaningful participation, people must first be informed about the current state of insect populations and the major threats they face. One impactful setting for fostering this awareness is within college entomology courses. While these courses traditionally emphasize insect anatomy, physiology, taxonomy, and ecology, they should also highlight the importance of conservation. When students are educated about the challenges facing insect populations, they are more likely to take action and may share their knowledge with others in the community.
