[citation needed] Since its introduction in Italy, the species has been observed to form population much denser than the ones in its native range.

[4] It was estimated that due to its similarities to another introduced planthopper, Metcalfa pruinosa, it is at risk of spreading further and becoming a pest.

[citation needed] In its native range, A. conica is very often living in association with three flatid planthopper species.

Eggs are laid in the summer and in the Autumn, individually encased in concavities cut inside woody tissue of the plant host.

[10] Both nymphs and adults produce abundant honeydew[4].This Hemiptera article related to members of the insect suborder Auchenorrhyncha is a stub.
