More than 80 percent of the world's insect species live in the tropics, yet conservation science largely ignores them. A new global framework from Monash University in Australia aims to fix that blind spot by pulling together local knowledge, museum records, and even social media posts.
The North-South Divide in Insect Data
Insects are the most diverse animals on Earth, with estimates ranging from 14 to 30 million species, most still undocumented. They pollinate over 80 percent of wild plants and feed 60 percent of bird species. But the scientific knowledge guiding conservation comes mostly from temperate regions, which hold only about 20 percent of insect diversity.
Dr. Shawan Chowdhury, who leads the Global Change Ecology Lab at Monash University's School of Biological Sciences, says this imbalance is dangerous. Conservation programs risk missing the very places where most insects actually live. The study, published in BioScience, brought together tropical ecology experts from around the world.
Four Barriers and a Wider Net
The researchers identified four major problems: poor visibility of existing research, severe data gaps, weak scientific infrastructure, and too little conservation action. To overcome these, they recommend using a much broader range of information sources.
That includes regional and non-English publications, museum collections, local expertise, citizen science, and observations shared on social media. The idea is to tap into knowledge that already exists but is not reaching global conservation databases.
Local people in tropical countries often know their insects well, but their observations rarely make it into international studies. Citizen science platforms and social media can help bridge that gap, offering low-cost ways to track species and population changes.
The framework also calls for better infrastructure in tropical regions, where scientists often lack funding, equipment, or training opportunities. Without that support, even the best data will not translate into protection on the ground.
Why This Matters for Global Food and Ecosystems
Insects are fundamental to functioning ecosystems and food production. They cycle nutrients, support food webs, and underpin agriculture. Yet they remain dramatically underrepresented in biodiversity monitoring, protected areas, and conservation policy.
For people living in the tropics, this is not an abstract issue. Their crops depend on insect pollinators, and their natural landscapes rely on insects to break down waste and feed other animals. When conservation plans ignore insects, they risk failing entire ecosystems.
The Monash team's framework offers a practical path forward. By combining formal science with local and digital knowledge, conservation efforts can finally start to cover the places where most insect species actually live. The question now is whether governments and research institutions will adopt this broader approach before more species slip away unnoticed.
