  • Mainly attacks currants (Ribes spp.) and lettuce
  • Adults (2-3 mm in length) have long legs and a spindle-shaped body that is green on Ribes spp. hosts, but can vary on other hosts
  • Aphid infestation results in leaf curl symptoms, dead hearts in head lettuce, and some stunting of plants
  • Fancy lettuce and leaf lettuce develop few symptoms
  • Honeydew production can result in sooty mould growth
  • Spread by wind or with infested plant material
