Physosterna cribripes, the desert toktokkie or woestyntoktokkie, is a flightless species of desert-dwelling darkling beetle or Tenebrionid found along the West coast of Namibia and Angola.

It is usually found in washes, on gravel plains and in rocky places, often climbing vegetation to feed.

[5] Most darkling species are omnivores, both as adults and larvae, feeding on the detritus of fresh and decaying plant matter, dead insects, and fungi.

Droplets condense by virtue of alternating hydrophobic, wax-coated and hydrophilic, non-waxy regions.

When the beetle adopts a head-down stance facing into the fog-laden wind, condensed water drains towards its mouthparts where it is swallowed.
