  Mua, Muah, Muas, Muak all are the equivalent of 'Mwah'. Onomatopeiac word for a kiss, ie on the end of a text message or email.
Bees see the world much differently than people do. A small cluster of tomato blossoms won't catch their attention, but a lawn peppered with clover and dandelions sends then into a pollinating frenzy. If you're serious about attracting bees to your vegetable garden, plant flowers.
Usually bees collect pollen from entomophilous plants that produce and the nectar. But in some periods of the season (especially in the early spring) when the honey plants are not yet in bloom or very few of them are in bloom, bees take this food from wind-pollinated plants.
