  1. † Both membrane types were covered by an extra layer of Parafilm to ensure similar appearances
  2. The change in number of females on two blood feeders with contrasting membrane qualities (sausage skin or Parafilm) used as reinforcing stimuli associated with chequered and white visual patterns for bi-directional conditioning was recorded. The position of each feeder was alternated every 2 min (see methods for details). Significant results are in bold
