Beetle Elytron Anatomy Diagram - Sclerite Identification Guide #2165199 (License: Personal Use)

This line drawing depicts the dorsal view of a beetle elytron segmented into three primary sclerite regions: region 3 is the humeral callus near the shoulder, regions 4 represent the paired discal areas covering the main surface, and region 5 marks the wavy apical margin. The suture lines indicate natural flexion points and structural boundaries critical for taxonomic classification. Such diagrams are essential for morphological keys in coleopteran systematics.

Used in entomology textbooks, online insect identification resources, museum exhibits, and academic papers to teach or reference elytron morphology; matches user intent for scientific illustration, species diagnosis, or educational material on beetle anatomy.
