About Hymenoptera
- Keeping it simple!


Hymenoptera: what do we want to talk about that topic for?  Well, here is an explanation of where bees fit into the grand scheme of things where insects are concerned, although this is just a simplified explanation.  So what am I talking about? Well, of course I’m talking about man’s obsession with trying to sort every living thing (tidily) into boxes – boxes with all kinds of labels (there aren't really any boxes, but if we imagine that there are, it might help us to make sense of it all). 

We start off with gargantuan, huge boxes, labelled with things like ‘animals’, ‘plants’, ‘fish’ and so on. Everything in these boxes gets sorted into smaller boxes, with more labels, and then even smaller boxes with yet more labels on those and so on. 

Eventually what you end up with are a number of large boxes containing lots of different types of wonderful, amazing creepy crawling things, with say, one box called ‘arthropods’, containing lots of smaller boxes with labels such as ‘arachnids’, ‘myriapods’ and insects – among others. 

Now we’re getting somewhere.  If you open up the box labelled ‘insects’, you get a further three boxes, one of which is a box specifically for winged insects which follow a very particular path of development as they grow from larvae to adult.

This box is called ‘ENDOPTERYGOTA’ (now come on, if you can pronounce the names of the different dinosaurs, I’m sure you can pronounce that one!).

And when you open up this box, you come upon a whole jumble of things – you guessed it, there are more boxes - a further 29 (phew!!), and FINALLY………

……….one of those boxes contains the insect family called ‘HYMENOPTERA’.

The Hymenoptera box is shared between all the different species of  bees, ants, wasps and sawflies!

About Hymenoptera

According to entomologist author, Steven Falk, around 150,000 hymenoptera species have been identified globally.  However, there are not doubt more to be discovered.  

  • There is some variation in explanations for the origin of the word 'hymenoptera'.  In the winged species (not all hymenoptera have wings - worker ants do not), there are two pairs of wings: the fore wings and a pair of smaller hind ones.  These wings are hooked together during flight.  These little hooks are called 'hamuli'.  In Greek mythology, Hymen (also called Hymenaeus) was the god of marriage, which is a form of 'joining together'.  Hence, it is said that the 'hymen' part of the word 'hymenoptera' refers to the joining together of the wings - or the 'married' wings.  Other sources state that the word 'hymen' means 'membrane', and refers to membrane wings. 

  • Females usually have an ovipositor for laying eggs, piercing, stinging or sawing.

Oh, and by the way, along with the wasp, you’ll find the hornet!

Actually, the wasp box in itself is an interesting box, because although most people think of the wasp as being a black and yellow stinging insect, there are many types of wasp of varying colours, such as brown, brown and white, or reddish coloured etc. Some wasp species do not even sting, and increasingly, certain species are used to control ‘pests’ on agricultural crops. Well I say, it's always better to work with nature rather than against it!

And just for a touch of added confusion to make things extra exciting, there are bees which look a bit like wasps, such as the nomad bee.

The Hymenoptera box also contains sawflies. The sawfly, not surprisingly, is so called because when viewed under a microscope, its ovipositor is saw-like in appearance. The sawfly uses their ‘saw-shaped’ ovipositor for cutting into plants, where they will then lay their eggs. Handy - but it doesn’t necessarily make sawflies very popular! Though if you're a hungry insect-eating bird, I'm sure you'll always appreciate the sawfly, ovipositor or not!

I have read that there are about 12,000 species of antPersonally, I like ants a lot! They are truly fascinating to watch. We have an ant nest near to our house, and I would never try to remove it. They’re great for the garden, as they eat some of the insects that like munching on my plants.

As I said before, not surprisingly, ants, like wasps, are starting to be used to control pests on crops. So gardeners – remember that!


Now the box called ‘bees' obviously contains all the different types of bees. However, there’s no point in me talking about bee species here in detail, when I’ve got pages about them!

Are bees invertebrates?

Quite simply, yesInvertebrates are animals which neither have nor develop a 'backbone' or 'spine' (vertebral column).

Are bees arthropods?

Yes, bees are also arthropods.  Arthropods are animals that have a hard outside covering called an 'exoskeleton'.  They also have segmented bodies and 'jointed appendages' (which means legs or limbs with joints - just like humans have elbow and knee joints).
