Over 60 species of native bees have been identified in Eastern Canada and Maine’s wild blueberry production regions.
“Pollinators are a diverse and fascinating group of animals. In addition to their beauty, pollinators provide an important link in our environment by moving pollen between flowers and ensuring the growth of seeds and fruits. The work of pollinators touches our lives every day through the food we eat. Even our seasons are marked by their work: the bloom of springtime meadows, summer berry picking, pumpkins in the fall.
There are 4,000 species of native bees in North America. Together they form the most important group of pollinators. Like all wildlife they are affected by changes in our landscapes, especially the loss of nesting sites. Bees make nests in which they create and provision brood cells for their offspring. In many modern landscapes, a desire for neatness has usually resulted in the removal of bare ground, dead trees, and untidy corners of rough grass—all important nesting sites for bees.”
-Matthew Shepherd, The Xerces Society of Invertebrate Conservation.
Bumble bees have an annual colony cycle that begins early in the spring when the overwintered queens emerge from their hibernation sites to feed on spring flowers and search for a suitable location for their new colony. Once the site has been found, the queen collects pollen, forming it into a lump that she lays her first brood of 7 or more worker eggs on. The pupation takes about 21 days. Once hatched they feed on the pollen lump, and additional pollen and nectar collected by the queen. This first group take over pollen and nectar collection while the queen continues to lay successive broods of worker eggs. By mid-summer, a colony contains between 20-100 workers, depending on the species. It is around this time that the colony begins to produce males and queens. The new queens leave the nest, and after mating dig 5-10 cm into the soil for hibernation. As autumn approaches, the remainder of the colony declines and dies. The hibernating queen emerges the following spring to begin the cycle again.

* When you first notice bumble bees in the spring place your new bee box outside in a safe, undisturbed place. Because bumble bees usually live in holes underground you will want to bury your box a few inches into the ground and extend the tube gently towards the surface. Only 1 in 4 boxes are occupied by bumble bees. If you’re box is not chosen take it inside and store until next spring when you can try again.
MASON BEE NEST BOX BUILDING-
MASON BEE- Osmia
Solitary Bees include leafcutter bee, mason bee or alkali bee. They emerge each spring never having met their mother. They develop in a stem, soil tunnel, or in an abandoned burrow made by another insect.
Each tunnel is filled with a row of compartments with an egg and mass of nectar-pollen. These compartments are sealed off with either leaves, clay or mud. The end of the tunnel is sealed with a heavier plug to keep the eggs safe. After consuming the larva’s share of pollen, the developing bee will enter diapause, passing through the rest of summer, fall and winter as a prepupa which is a sort of suspended state. Then as spring approaches they complete rapid pupal development. Once they complete their metamorphosis and become adults and emerge from their compartment to mate right away, ideally with individuals from a different nest. The male dies soon after mating, and the female then does the environment an invaluable service of collecting pollen from the flowers that are blooming around her. The pollen collected is used to provision her own nest as the other of the next generation.
Collecting Knot Weed
*Please make sure that you remove all seed from your cuttings so that you do not accidentally spread the unstoppable knot weed.
1. Find a patch of knot weed
You will need
– 2 pieces of 2×8” untreated wood cut into 13” lengths.
– 2 metal brackets
– weather resistant rope
– knot weed, bamboo, raspberry canes or any naturally hallow plant. Cut into approx. 6-8 inch lengths.
1. Prepare your knot weed or other hallow stemmed plant into lengths that are 6-8″ long.
3. Lay the hallow stalks in the roof, now looking at the stalks as though they are water in a bath tub mark four dots that are just below the water line. This will allow you to tightly fasten them in with rope in a moment.
4. Drill holes where you made your marks.
5. Lay the hallow stem lengths with the openings facing the front without the brackets.
