Bee consistency. Some solitary bees have advanced types of pollen-carrying structures on their bodies. A very few species of solitary bees are being cultured for commercial pollination. Most of these species belong to a distinct set of genera which are commonly known by their nesting behavior or preferences, namely: carpenter bees, sweat bees, mason bees, plasterer bees, squash bees, dwarf carpenter bees, leafcutter bees, alkali bees and digger bees. Most solitary bees nest in the ground in a variety of soil textures and conditions while others create nests in hollow reeds or twigs, holes in wood. The female typically creates a
Calendar of the Digger digger sows seed. He also works the plains, in which the grapevine trenches are refilled; the filled grapevine trenches are then prepared. In April, the digger turns the soil of the plains adapted for Turkish grains, hemp, and beans. The digger must prepare more grapevine trenches. An aerator is used to prepare the fields for watermelons, sweet melons, and other plants. In May, the digger shovels the beds where the beech trees and beans will be planted, finishes preparing the grapevine trenches, prepares grapevine grafts, and digs all of the trenches for the grapevines left from the year before.
