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.
This is a list of crop plants pollinated by bees. Most of them are pollinated in whole or part not by honeybees, but by the crop's natural pollinators, like bumblebees, orchard bees, squash bees, and solitary bees. Where the same plants have non-bee pollinators such as birds or other insects, these are also indicated. Pollination by insects is called entomophily. Entomophily is a form of plant pollination whereby pollen is distributed by insects, particularly bees, Lepidoptera (e.g. butterflies and moths), flies and beetles.
