Gustatory responsiveness and tactile acquisition of outdoor winter bees, summer nurse bees and summer foragers. (A) Sucrose concentration response curves of outdoor winter bees, summers nurse bees and summer foragers. The x-axis displays the sucrose concentration offered to the antennae of each bee. The y-axis shows the percentage of bees showing the proboscis extension response (PER). (B) Tactile acquisition curves of outdoor winter bees, summers nurse bees and summer foragers. The x-axis displays the conditioning trials. The y-axis shows the percentage of bees showing conditioned PER. (C) Gustatory response scores (GRS) of outdoor winter bees, summers nurse bees and summer foragers. The x-axis displays the different groups. The y-axis shows median GRS (dots) and 25% (lower line) and 75% (upper line) quartiles. (D) Tactile acquisition scores of outdoor winter bees, summers nurse bees and summer foragers. The x-axis displays the different groups. The y-axis shows median acquisition scores (dots) and 25% (lower line) and 75% (upper line) quartiles.
