Advances in digital technologies are increasingly applied in nature education and forest diagnostics. Also, 3D modeling of insect feeding grounds is becoming more and more common in science. This study explores the use of 3D models as a didactic tool in forest entomology, aimed at improving both the learning process and the accurate identification of characteristic features of beetle larval galleries.
Data acquisition involved digital photography of original saproxylic beetle galleries, followed by photogrammetric reconstruction in the Meshroom software. This technique allows for the reconstruction of three-dimensional objects based on a series of two-dimensional images and ensures a high level of detail. The resulting models were refined and textured in the Blender software to create high-resolution visualizations that accurately reflect the structural features of the individual galleries. Eleven saproxylic beetle species were selected to show the diversity of larval galleries of tree-damaging insect species and to present larval galleries in different host tree species. A total of eleven 3D models representing different beetle species and host tree types were developed (Table 1). These interactive models complement traditional teaching resources such as illustrations, photographs, and dry specimens, allowing users to examine the morphology of the galleries from multiple perspectives and at any scale. Image acquisition required 456 photographs in total, and took about 18 hours of shooting. The model processing took 8 hours and resulted in the creation of 1.65 GB compressed files.
The study demonstrates the potential of 3D visualization to enhance modern education and forest diagnostics. The main advantage of using such models and creating virtual guides from them is the possibility of easy storage, multiple playback and accessibility. It represents a step toward the digitization of educational resources and the dissemination of environmental knowledge to a broader audience. Beyond its didactic applications, the approach offers opportunities for digitizing and preserving entomological collections, thereby increasing accessibility while minimizing the need for physical handling of fragile specimens. Moreover, this work shows that the use of such techniques provides a tool supporting the identification of feeding grounds, which may contribute to more effective monitoring and management of forest health.
