Frequency histograms for Trithemis forewing and hindwing shape distinctions for species preferring different landscape and water body habitats as assessed from the wing-image datasets using the embedded LeNet-5 deep-learning algorithm. Note the complete, and quite marked, separation that was achieved for these habitat-based wing morphology differences in the case of both forewings and hindwings. Comparison of these results with those of the linear-model analyses (Figs. 7 and 10) suggests that the geometries of morphological differences between these habitat groups exhibit a strongly non-linear character
