Researchers at Monash University have developed a framework to address critical shortcomings in tropical insect conservation efforts. Led by Dr. Shawan Chowdhury, the international team published their findings in BioScience, bringing together experts from eight countries to examine barriers to protecting insects in regions where biodiversity is most concentrated.
Insects represent the most diverse group of animals on Earth, with scientists estimating between 14 and 30 million species exist. These organisms play fundamental roles in ecosystems, pollinating over 80 percent of wild plant species and serving as food for 60 percent of bird species. Despite their ecological importance and evidence of declining populations, most conservation knowledge derives from temperate regions that contain only about 20 percent of global insect diversity. This geographic imbalance in research creates a significant risk that conservation programs will not reach areas where insect species are most abundant.
The research team identified four major obstacles limiting tropical insect conservation: limited global visibility of existing research, substantial data gaps, inadequate scientific infrastructure, and insufficient conservation action. To overcome these challenges, the framework recommends integrating diverse information sources beyond conventional scientific publications, including regional studies, non-English publications, museum collections, local expertise, citizen science, and social media observations. The researchers emphasized the importance of strengthening local scientific capacity and ensuring evidence reaches policymakers who can implement conservation decisions.
Bangladesh served as a case study demonstrating both the challenges and opportunities for improved insect conservation. Researchers identified 111 butterfly studies in the country, though only 34 appeared in international journals. Social media platforms unexpectedly provided valuable biodiversity data, with Facebook containing records for 167 of 169 threatened butterfly species. However, only one of 226 butterfly species studied had adequate representation within the country’s protected areas system.
The framework advocates moving away from “parachute science,” a model where tropical communities primarily serve as data sources rather than research partners. Instead, the proposed approach emphasizes locally-led research, expanded regional scientific infrastructure, improved taxonomic expertise, sustained monitoring programs, equitable international partnerships, and strengthened connections between scientists and decision-makers. The study included contributions from researchers in Australia, Bangladesh, Uganda, Hong Kong, Brazil, Czech Republic, Italy, and India.
