Figure 4. (a) Transmission (TEM) and (b) scanning (SEM) electron microscopy of threads of the water mites Limnochares aquatica (L.) from the thread balls. (a) Transverse section of the thread showing a dense core (arrowhead) at some distance from a thick wall (arrow). Scale bar = 1 µm; (b) bunch of the threads possessing a core (arrowheads) enclosed within the thread wall (arrows). Scale bar = 10 µm.
