Aphids Secrete Water-Repellent Material

Aphids secrete wax, which they use to coat their waste (known as honeydew) and the inner wall of their nests. This allows them to expel honeydew from their nests as it accumulates.

Form/Organization/System:: Decomposition

Defense/Stability:: Water repellent

The wax produced by the aphids creates a ball of liquid with a hydrophobic coating. This process could be used to create hypoallergenic stoppages for medical purposes, as well as waterproof shipping packaging.

 0Pemphigus spyrothecae create spiral-shaped galls on poplar and other trees. Aphid waste is typically removed by ants, but aphids that live in galls must dispose of their waste themselves.
