Is A Bee An Insect?
What Is A Bee?

Read on for a more detailed explanation:

Is a bee an animal?  

Yes, bees are animals in that bees, like all invertebrates, are part of the Animal Kingdom. 

To explain further, all living things are classified into groups based on shared characteristics, which are then subdivided multiple times into even smaller groups based on even more features that they share in common.  

In this way, living organisms from bacteria and fungi to plants and trees, insects, fish, birds, large and small animals are put into yet smaller clusters with individual species that are increasingly similar in the physical features they share. 

The first (or top) layer of groups are called ‘kingdoms’ and all living things are further classified from these.   As well as kingdoms for plants, bacteria and fungi, we have the Animal Kingdom, which includes vertebrates and invertebrates.

Are bees also mammals?

Although bees have hairs on their bodies as mammals do, and are part of the animal kingdom, bees are not mammals. 

Mammals are warm-blooded vertebrates with mammary glands for feeding milk to their young.  Bees are cold-blooded invertebrates and provision their larvae with food  - usually a combination of nectar and pollen.

What Makes A Bee An Insect?

An insect is an invertebrate (animal without an internal  backbone), and insects have:

• a body in 3 parts: head, thorax and abdomen.  
• a pair of antennae, 
• 3 pairs of jointed legs and 
• compound eyes. 

A bee has all of these features, and is an insect.  You can contrast this with say, a spider, which is not an insect but an arachnid, having 8 legs (4 pairs), no antennae, and 2 body parts (a head and thorax which are merged into one body part,  and the abdomen).

Why is a bee a not bug?

Although a bee is an insect, it is not a bug.  Bugs are types of insects, that have piercing mouth parts for sucking juices either from other insects, animals or plants.   

Bees belong to the insect order Hymenoptera, where as bugs belong to the insect order Hemiptera, meaning 'half wing' and refers to the fact that part of the first pair of wings in bugs is toughened and hard.   

Bees share the same insect classification (hymenoptera) with wasps, ants, sawflies and also hornets.

Is a bee a type of fly?

No, although bees and flies are insects, flies belong to the insect order Diptera. 

Flies have 1 pair of wings (bees have 2 pairs of wings). Their mouth parts are for piercing or sucking.  As explained above, bees belong in the insect order Hymenoptera.

Above is a photograph of a conopid fly which is a parasite of bees.  In flies, the eyes are typically at the front of the head and are forward-facing.  It has one pair of wings and short antennae.  

Some flies look a little like bees, as is the case of the bee fly which is actually a parasite of various species, especially of solitary bees. Read about the bee fly.

In summary....

Bees, true bugs and true flies are all insects, but separate at the classification level of 'Insect Order' - see below:

Is a bee a type of wasp?

Bees and wasps are closely related, and even belong to the same insect order (Hymenoptera) and sub-order - (Apocrita), however, they are classified differently at the next level of classification, which is Superfamily:

Please note that the term 'meat bee' in some regions of the world actually refers to a wasp, notably yellow jackets. 

However, a very small number of tropical bee species do in fact eat meat!

Is A Bee An Invertebrate?

Yes, bees are invertebrates.  An invertebrate is an animal without an internal backbone (spinal column).  Bees have no backbone, only an exoskeleton, which is a thin, shell-like outer skeleton.
