If robbers and pollinators forage at different times of day, plants may produce nectar according to the active period of a legitimate pollinator. This is an example of a defence by escaping in time. Another way to use time in defence is to flower only for one day as a tropical shrub "Pavonia dasypetala" does to avoid the robbing Trigona bees. Escaping in space refers to a situation in which plant avoids being robbed by growing in a certain location like next to a plant which is more attractive to the robbers.
