Fig 4.

The adhesive droplets of the threads in A. luminosa are A) evenly distributed and B) ellipsoid shaped, with a C) central orientated thread. Maintaining the thread at a humidity of 30% results in the disappearance of the droplet at the macro level, only the D) thread and the droplet area remain visible. At a higher magnification (see yellow bracket) E) two evenly-spaced regions could be identified, an upper one (blue plus) with a shiny metallic appearance and a lower, dark region (red hash).
