Magnification considerations: (a) Elytra images captured at 50 ×  magnification, showing their overall appearance; (b) Elytra images of T. castaneum (TCa) and T. confusum (TCo) at various magnifications showing area of elytra captured in each frame/magnification, (c) variation in average elytra sizes (of 10 images per species) for the seven different species used in this study, (d) proportion (area imaged/total area) of elytra captured at various magnifications, (e) number of images required (elytra size/frame size) to visually represent the whole elytra and (f) change in frame area (area captured in an image) by magnification. Even though there is a variation in elytral sizes, collectively they can be represented effectively at a magnification of 100 x.
