This leads to shifts in pollination syndromes and to some genera having a high diversity of pollination syndromes among species, suggesting that pollinators are a primary selective force driving diversity and speciation. [5] [6] Ophrys apifera is an orchid species that has a highly evolved plant-pollinator relationship. This specific species ...

If robbers and pollinators forage at different times of day, plants may produce nectar according to the active period of a legitimate pollinator. [7] 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 ...

Nonetheless, an estimated 87.5% of the world's flowering plant species are animal-pollinated, [36] and 60% of crop plant species [37] use animal pollinators. This includes the majority of fruits, many vegetables, and also fodder. [38] According to the USDA 80% of insect crop pollination in the US is due to honey bees. [39]
