Distribution

This species can be found in most of Europe eastward to Ukraine and Turkey, and in the Nearctic ecozone (it has been introduced to North America).[3]

Description

Aphis genistae can reach a length of 1.4–2.6 millimetres (0.055–0.102 in). Apterae are black, coated with wax meal, while alatae have 4-8 secondary rhinaria.[4]

Biology

These insects mainly feed on small branches and flowers of Genista anglica, Genista lydia and Genista tinctoria (hence the species name),[5] but they have also been collected on Laburnum, Cytisus, Petteria, Spartium and Sophora species.[6] These aphids sometimes have a mutualistic relationship with ants. They are holocyclic (sex is involved, leading to egg production) and oviparae. Sexual females mate with the alate males in September to produce overwintering eggs.[4]

gollark: Well, yes.
gollark: It does seem like terrorists are weirdly ineffective. If I wanted to destabilize Western civilization I expect I could do a better job.(Hi government agents!)
gollark: Well, terrorists do, presumably. For terror.
gollark: I use Syncthing for my personal sync needs personally. It does that but P2Pishly without requiring cloud™ somewhere.
gollark: Seriously? That seems vaguely implausible. The Pi's SoC may be newer than... Core 2 Duos or something, but the A72 cores in it are *not* particularly new and as far as I know quite bad.
