Scanning electron microscopy (SEM)

Left antennae, endoterga and terga were dissected. The samples were cleaned and dehydrated via an ethanol series (2× 96%, 3× 100%) prior to mounting on aluminum SEM stubs. The samples were coated with gold for 240 seconds in a sputter coater. SEM images were then taken using a Supra VR 300VP (Carl Zeiss AG, Oberkochen, Germany) scanning electron microscope utilizing SmartSEM V05.00 software based at the ZFMK. Dry-coated SEM material was then removed after study from the stubs and returned to alcohol. All images were later edited using Adobe Photoshop CS2 and assembled into plates with Adobe Illustrator CS2 (San Jose, USA).
