The photographs (Figs. 1, 2) were taken following the method described by Taszakowski and Kaszyca65 (link). To prepare high-quality photos that would enable advanced processing (e.g., obtaining a uniform background), the specimens were glued on transparent entomological glue boards and then cleaned with a thin brush. For better visibility of details, pictures of antennae were taken with the use of a dark background. The Focus-stacked, colour photographs were captured using the following equipment: Leica M205C (stereomicroscope), Leica LED5000 HDI (high diffuse dome illumination), Leica DFC495 (digital camera), Leica application suite 4.12.0 (software) (Leica Microsystems, Vienna, Austria), Image Composite Editor (panoramic image stitcher) and Adobe Photoshop CS6 graphic editor.

Antennae of examined species in light microscopy and SEM: L. occidentalis (a, b) and L. zonatus (c, d).
