Document Summary
Flower constancy, insect psychology, and plant evolution summary. Flower constancy is likely to have multiple causes. Temporal limitations on retrieving information from long-term memory as rapidly as from short-term memory. Retrieving may be more prone to errors when there are multiple options than when there is only a single task. Evidence against the notion that pollinator constancy is involved in speciation or maintenance of plant species integrity. Since optimal foraging strategy suggests going the shortest distance between food sources, flower constancy is counter-intuitive. If insects visit only a single flower species (excluding reasons for preference), then flower constancy is bound to be based on learning. Working memory used in place of stm since it can be altered and used in combination with ltm or new incoming information. Ltm capacity in bees is too large to explain constancy. Bees have large ltm in order to remember how to navigate back to their nest and remember where flower patches are.
