Can 3D Imaging Help Scientists Identify and Study Insects?

What is it about?

Identifying and describing insect species is essential for understanding biodiversity, ecosystems, and conservation, but traditional taxonomy often relies on specialist skills, physical specimens, and detailed microscope work. New digital tools, such as photogrammetry, offer alternative ways to study insects by creating detailed 3D models from photographs. This paper explores how photogrammetry and 3D scanning can support insect taxonomy. The authors examine how well these techniques capture important anatomical features and where they are most useful, for example in sharing specimens digitally, supporting identification, or preserving fragile or rare samples. The study also discusses the limitations of 3D scanning. Some small or fine structures may not be easily captured, and the technology cannot fully replace traditional methods. Instead, the authors show that photogrammetry works best as a supplementary tool alongside established taxonomic approaches. Overall, the research provides a balanced assessment of how 3D imaging can enhance insect taxonomy while recognising its current constraints.

Why is it important?

Accurate insect identification is vital for research, conservation, and monitoring environmental change, yet taxonomic expertise and access to physical specimens are increasingly limited. Digital tools like photogrammetry have the potential to make insect specimens more accessible, shareable, and reusable across the scientific community. This study clarifies what 3D imaging technologies can and cannot currently achieve in insect taxonomy. By identifying both opportunities and limitations, it helps researchers use these tools appropriately, supports better digital documentation of biodiversity, and contributes to more efficient and inclusive taxonomic research in the future.
