It is one of 5 ''Aphthona'' spp. that has been used in Alberta, Canada to control leafy spurge, an invasive plant that reduces pasture quality and degrades natural habitats.〔Bourchier, R., Erb, S., McClay, A, and Gassman, A. 2001. Euphorbia esula (L.) (Leafy spurge) and Euphorbia cyparissias (L.) (Cypress Spurge) (Ephorbiaceae). In Mason, P. and Huber, S. (Eds). Biological contorol programmes against insects and weeds in Canada 1981-2000. CABI Publishing, Wallingford, UK.〕 It, along with ''A. lacertosa'', is one of only two biocontrol agents thought to be effective against leafy spurge. 〔 Larvae cause the most damage to the plant by feeding on the roots. ==Nontarget impacts== ''A. nigriscutis'' will feed on the native ''Euphorbia robusta'' Engelm, though this is thought to be acceptable as the weevil significantly reduces leafy spurge populations over time.〔 (【引用サイトリンク】author = John L.
