Bees will have four wings, flies will have two (wasps will also have four). But this is very difficult to see in the field and often requires catching the bee.
Female bees will have dense hairs on their legs and body used for collecting pollen. Wasps will not have these, and seeing an insect with a yellow blanket of pollen on its legs or bum is a dead giveaway its a bee.
Bees will have segmented bodies that are a bit ‘chunky’, whereas wasps will often be more skinny especially around the ‘waist’. Flys will look more like a blob with legs and wings.
Bees tend to have a similar flying style. They move around flowers in a sort of figure of eight motion and will be less direct then flies.
11 species of social stingless bees are native to Australia, and they are the ONLY Aussie species that are social, meaning they live in hives, mostly in trees, and make honey (Scientific names: Tetragonula and Austroplebeia).
They are very small roughly 2-4mm in size and don’t have a stinger, but can give you a nasty bite!
The honey they produce is very different to European bees and has a distinctive flavour.
The Blue Banded Bee (Amegilla sp) is one of the most charismatic species in the world and they live here in Australia.
They are solitary and nest in holes in masonry or the ground with the males ‘roosting’ on branches as they sleep, shown above. Sometimes they will share nesting sites.
Inside a hole, the females will lay an egg in a wax cap that will contain pollen and nectar. The egg hatches into a larva which will eat the mixture and then turn into a pupa before emerging as an adult bee!
The Great Carpenter Bee (Xylocopa aruana) is the largest species of bee in Australia, nearly 10x the size of a stingless bee.
They are solitary and nest in deadwood and have a similar life cycle to blue banded bees.
Male and female carpenter bees look very different which is similar to many other species of bee worldwide. Females have a black abdomen and yellow thorax as pictured above, whereas males are golden or pale brown all over.

This is a European Honey Bee (Apis Melliferna).
They are invasive in this county and compete with native bees for pollen and nectar. They are common in urban areas and are especially hardy, meaning they can survive harsh conditions that native species cannot. They are also generalists and will forage on many different species of flowers, whereas some native bees may be reliant on one host plant.
In Tasmania, the invasive Bubble bee (Bombus sp) has also established but has not reached the mainland.

Wasps are also pollinators and there are over 12,000 species in Australia! They are related to bees (both in the order Hymenoptera) but often feed on other insects rather than the vegetarian diet of bees.
Because of their diet, they don’t have as many hairs on their body called a pollen brush in bees), as they are not collecting pollen from flowers. They are also often more slender than bees and have a thin ‘waist’, which is key in telling the difference between the two.
Wasps are often overlooked and seen as pests but they are crucial for pollination and for controlling other insect populations.

There are roughly 160 species of hover flies or flower flies in Australia. They have evolved to look like bees and wasps to deter would be predators by making them believe they have a stinger. But don't overlook them as they are crucial pollinators!
