Morphology
The phrase is a straightforward descriptive noun compound: 'green' (color) + 'peach' (host/plant) + 'aphid' (sap-sucking insect) yields the meaning 'a green-colored aphid associated with peach trees'. This compositional pattern is literal and cross-linguistically common, so a B1 learner who knows the constituent words would readily infer the MWE's meaning.
Etymology
Green peach aphid gets its name from how the insect looks and where it lives: it is a small green aphid that often feeds on peach trees. Because it eats plants and spreads disease, farmers call it a 'pest'.
