Are Bees And Wasps Related?

This is a common question, and yes, bees and wasps are related.  They both belong to the insect order Hymenoptera, and also to the suborder, Apocrita.  The suborder Apocrita includes wasp-waisted insects that also have grub-like larvae that develop within a host species, gall or nest. 

In fact, the consensus is that bees evolved from wasps.

“Wasps (including hornets and yellow jackets) and bees are close relatives, sharing in common a grandmother 100 million “greats” ago.” – Wilson & Messinger Carril, authors of Bees In Your Backyard.

Steven Falk, author of Field Guide to Bees of Great Britain and Ireland also states:

“There is little doubt that within the Apoidea, the hunting wasps came first and provided an ancestor that gave rise to bees” .

Falk also notes that bees (and also ants) are actually specialized wasps, and interestingly, certain hunting wasps are more closely related to bees than they are to other types of wasps.  These are wasps of the Crabonidae (e.g. digger wasps) and Sphecidae (sand wasps).  

Misidentification: bees may look like wasps more often than you might think

The image that many people have of a bee is actually stereotypical of just one type: the bumble bee (Bombus).  However, there are many different types of bees and appearance is diverse – for example, some bees are bright green and quite different from Bombus.

Given the diversity in appearance, and that bees and wasps are related, it’s no surprise then, that misidentification between the two can occur, especially when the image that so many people have of a bee is limited to one type.


Example of bees that look like wasps 

For non-scientists, confusion can easily arise with fairly common species.

Below is a species of nomad bee (Nomada) - the Gooden's Nomad Bee, Nomada goodeniana.

Gooden's Nomad Bee - Nomada goodeniana could easily be mistaken for a wasp.Gooden's Nomad Bee - Nomada goodeniana is a bee that looks like a wasp.


Nomad bees are very wasp-like in appearance.  They are cleptoparasitic bees that target other bee species (the host) - i.e.  cleptoparasites are organisms that take over the nest or nest cell of the target host species.

In doing so, the cleptoparasite's offspring feed off the food supplies intended for that of the host.   Nomad bees typically lurk outside bee nests (often Andrena – mining species), enter and lay an egg inside a nest cell.  The emerging nomad bee grub kills the host’s offspring and snaffles the food intended for it.

In contrast, this hunting wasp (below) of the Crabonidae family, Argogorytes mystaceus (commonly known as the Field Digger Wasp) is not a cleptoparasite, but may be host species to other parasitic wasps species, such as the cleptoparasitic nyssonine wasp, Nysson spinosus.  

You'll note that whereas this wasp is black with yellow stripes, the bee above is yellow with black stripes.  They are about the same size as each other, and for those unfamiliar with these species of bee and wasp, the nomad bee could be mistaken for a wasp.

Like Andrena (mining) bee species, the Field Digger Wasp burrows a tunnel into soil and creates nest cells in which it lays an egg, then provisions the cell with food for emerging grubs.  

The small Field Digger Wasp is very similar in size to a Nomad Bee.

A key difference however, is that whereas bees provide food for their young in the form of nectar and pollen, wasps – including the Field Digger Wasp, provide food for their grubs in the form of other small invertebrates, such as bug nymphs (although there are exceptions, such as meat eating bees - and there are wasps that feed pollen to their offspring).

  Field Digger Wasp:

  • Wasp
  • Makes a burrow and nest cells where its young are reared, just like Andrena (mining bees).
  • Provisions each nest cell with food such as bug nymphs for its young. 


  Gooden's Nomad Bee:

  • Bee
  • Is a cleptoparasite, so it doesn't make its own nest - instead it uses that of the target host.
  • For feeding its young, it relies on the food provided by the host bee for its own offspring.


Interestingly, the Field Digger Wasp is more closely related to bees than to social wasps such (Vespidae).

Another type of bee that can be mistaken for a wasp include wool carders that have more yellow on their bodies.

Anthidium manicatum, Wool Carder Bees can look similar to wasps, depending on the amount of yellow on the body.Anthidium manicatum, Wool Carder Bees can look similar to wasps, depending on the amount of yellow on the body.


This is just two examples of bees that may be mistaken for wasps, but of course there are others.


Even scientists can make mistakes!


The similarity between wasps and bees can even sometimes result in misidentification for experienced scientists.  A bee called Neolarra was originally thought to be a wasp when it was first discovered by scientists.
