We are now observing good growth on the emerging herbaceous plants. Taking a closer look at the emerging foliage on some reveals colonies of bugs and beasties. This image of a Lupin cultivar shows an active colony of Lupin and Macrosiphum albifronsLupin Aphid, Macrosiphum albifrons.
Not easy to control culturally or organically, repeat spraying with dilute dish washing water may reduce the population but never totally wipes it out. Lupin and Macrosiphum albifrons
These aphids overwinter within the shelter of the dead basal foliage, grasping the chance to feed on the fresh sap. These are wingless adults, winged adults appear during the summer when the colony is too large to support itself and these fly away on the breeze to colonise other Lupin plants.
