Australian native bees are very tiny compared to the honey bee, which for many people is a "real bee".
This is a honey bee. Note her size compared to the Eucalypt blossom.
Now compare her to one of our tiny native bees.
Here are two flowers (one native, one not) with the dainty native bee hard at work collecting pollen. You can clearly see the store gathered on the hind legs. I am not a bee expert but I think these two bees are in the Trigona family, stingless bees
Brachyscome Multifida 'Break of Day' is a favourite with our tiny bees.
