Next time you are out in the garden check out your flowering plants, clumps of dried grasses and old holey timber - any insects about may be native bees. Many are very small- the Reed bees and Homalictus bees may be only 3-5mm long. Blue bandeds are thumpers- nearly the size of a Honeybee but much faster.
