Discovery times on plain and patterned flowers at the beginning and end of foraging trips.

<p>On both the first and last flower of the trip, bees visiting flowers legitimately discovered nectar more quickly when flowers were patterned (diagonal hatched lines). When flowers were patterned, legitimate foraging was faster than robbing; when flowers were plain, discovery times for both handling strategies were ultimately similar.
