The Black Dot Spurge Flea Beetle, Aphthona nigriscutis, is the most successful of the five species of flea beetles we offer to attack leafy spurge. Adults will feed gregariously on the leaves and bracts of leafy spurge. Females will lay an average of 225 eggs at the base of spurge plants. The larvae will feed internally and externally on the primary and secondary roots and cause considerable damage to plants. Our customers are observing dramatic declines in spurge plant density and vigor in areas where the flea beetles are established. Releases of 440 adults are available in June and July for $50.00.
USDA researchers in Montana found that Aphthona flava releases reduced leafy spurge infestations in field plots from 57 percent of canopy cover to less than 1 percent in just 4 years.

Aphthona lacertosa, the Brown-Legged Spurge Flea Beetle, has demonstrated the same dramatic impact on spurge as the other three species above. We are able to offer 440 adults of this species for $50.00. This represents a savings of 75% over previous prices!
