It is very powerful to know you are an important part of a system.
This is a newly hatched Queen bumble bee in my garden. I have attempted to define the roles we play below.
She will; pollinate a few plants while she builds up her reserves for overwintering and then in early spring when out of dormancy, build up a brood of worker bees that will pollinate my garden all growing season.
I have made; nesting boxes for her 'mother' and then her to raise their brood, sure there are overwintering sites for her, made sure there are food sources available for her and her mother when they need to build reserves (early spring and autumn), sure of a diversity of food crops throughout the whole growing season to support the whole nest of workers, there is clean water and no pesticides or herbicides used.
