Pollinator or pollen. Female orchid bees act as pollinators, but of flowers other than orchids. Eusocial bees such as honey bees need an abundant and steady pollen source to multiply. Honey bees travel from flower to flower, collecting nectar (later converted to honey), and pollen grains. The bee collects the pollen by rubbing against the anthers. The pollen collects on the hind legs, in a structure referred to as a "pollen basket". As the bee flies from flower to flower, some of the pollen grains are transferred onto the stigma of other flowers. Nectar provides the energy for bee nutrition; pollen
Minuartia groenlandica it does flower anywhere between June to August. In this period pollen grains are transported from flower to flower by insects. The most effective insect to transport pollen grains is the bumblebee "Bombus terricola". This is due to tiny hairs on the bee that collect pollen, and the bee's habit of crawling all over the flower in low temperatures when it is too cold to fly. Greenland stitchwort is found in areas of high elevation where bedrock is exposed. The plant grows on rocky ledges and in fine gravel on slopes. The soil in this area has a pH of
