It is used as an agent of biological pest control against the noxious weed leafy spurge (Euphorbia esula).

The female lays eggs on the soil next to leafy spurge, its host plant, during the summer months.

It goes to work feeding on the roots of the plant throughout the winter and spring and then pupates in the soil until emerging as an adult in early summer.

With this realization A. czwalinae stopped being an important component in Aphthona leafy spurge control.

[1] A. czwalinae had not been verified to persist in North Dakota or Minnesota for several years,[2] until Roehrdanz documented it in Eastern Montana in 2006.
