The Border Crossing Card (BCC) is acceptable as a stand-alone document (by itself) only for travel from Mexico by land, or by pleasure vessel or ferry. Together with a valid passport, though, it meets the documentary requirements for entry at all land, air, and sea ports of entry (to include travel from Canada).
Anthecology is the scientific study of pollination. Insect pollinators include bees, (honey bees, solitary species, bumblebees); pollen wasps (Masarinae); ants; a variety of flies including bee flies and hoverflies; lepidopterans, both butterflies and moths; and flower beetles.uglossine bees pollinate orchids, but these are male bees collecting floral scents rather than females gathering nectar 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.
Cuckoo species â such as cuckoo bumblebees also do not gather pollen, since they also have no pollen baskets, however, they do require it, but rely on the host bumblebee species to supply their needs. So letâs look at the requirements of the different types of bees.oney bees need nectar and pollen for much the same reason as bumblebees and solitary bees, although they treat it slightly differently. The nectar that is gathered by honey bees is taken back to the nest or bee hive.
