Air Sifter Challenge

Organisms entered into this contest have to, whether actively or passively, gather food sifted from the air. What that means specifically, and how to approach it, is up to you.
They don't have to necessarily exist in the atmospheric biomes, there are plenty of things closer to the ground that are available to be sifted.

A real life example of an air sifter are orb weaver spiders.

Entries must be done prior to the end of generation 167, and must be indicated as entries for the contest in their text body or subheading.
