Generations per year:  One

Growth:  4 stages of growth

Egg—200 to 300 eggs are deposited in small batches underground during the summer near the root of the spurge

Larval—newly hatched larvae migrate to the root hairs and feed until cool fall temperatures force dormancy

Pupal—pupation occurs in a soil cell from late spring to early summer 

Adult—emerge throughout the summer and feed on leafy spurge leaves. Adults are 0.12 inches long (tiny) and black.

 Overwintering stage—larval—in the spurge roots

Destructive stage—larval (root hairs and young roots) and adult (leaves and flowers)

Impact on the Leafy Spurge—the insect does not kill the plant, however, it reduces the plant’s root reserves and its ability to replace them

Habitat:

  • ·          Steppe areas with loamy soils
  • ·          Well-developed herbaceous vegetation

Dry sites or flooded areas are unfavorable to beetle survival.

Release Date:  Brown-legged Leafy Spurge Flea Beetles are typically released in June and July.
