An endangered species is a taxonomic group (typically at the species level) that faces a very high risk of extinction in the near future across all or a significant portion of its range, as determined by quantitative assessment criteria such as population size, rate of decline, geographic range, and degree of habitat fragmentation. In conservation biology and environmental policy, endangered status guides prioritization of management actions, legal protections, and resource allocation. Scientific evaluation commonly uses standardized frameworks (e.g., formal Red List–type criteria) based on demographic trends, reproductive rates, and known or projected threats, including habitat loss, overexploitation, invasive species, pollution, and climate change.
Invertebrates, including insects, are poorly represented on the International Union for Conservation of Nature's (IUCN) Red List. The Red List, the world's most comprehensive information source on global conservation status, ...
