Lupin aphid

Symptoms

Foliage becomes sticky and a whitish waxy deposit also coats the leaf surfaces. The impact of this sap-sucking insect can mean that plants may wilt and die.

Spot them

Large (4-5 mm long) greyish green aphids in dense colonies can be seen in early summer on the underside of leaves and on the flower spikes. Populations peak from late May to July.
