Carpenter bees

These bees have powerful mandibles (jaws) that can dig tunnels in wood. Xylocopa violacea (left), a huge (20-23 mm long), black bee found in central and southern Europe nests in dead wood and digs a tunnel up to 30 cm long containing 10-15 cells. This bee holds the record for laying the largest egg of any insect.

Carpenters are found in many parts of the world, and there is a bee almost identical to this commonly found in the USA. Naturally a large number of carpenter nests in the structural support of a building will cause some damage, but this is unusual.

One behaviour can be alarming though. The males compete with other males to mate with females. This involves them chasing males away and chasing females to mate. During these chases they zoom about crashing into windows, people and anything else in their path. Humans in the way of all this may think they are under attack, they are not, they are just in the way. Males may also hang around waiting for adult females to emerge, and again they behave in what might seem to us as an aggressive way, by chasing other males away and investigating anything that gets near the exit hole. This something may be your head, you will be buzzed around and checked out to see if you are a rival that needs chasing away or a female that needs mating. However there is no danger as males cannot sting, so like much male mating behaviour it's all bluster and show. Male and female carpenter bee and male mining bee

Mason bee Anthophora sp.

Mason bees.

These bees will nest in almost any cavity which they can modify in shape with earth or other materials to suit their requirements. Some species specialise in nesting inside snail shells, and there is a tiny species that nests in the holes left by wood worm beetles. The European species Osmia rufa is often found nesting in old nail holes and in the mortar of old walls. Others, like Anthophora retusa, on the left construct cells using clay, sand, earth and chalk, and earth mixed with wood - whatever is at hand. In towns their nests can often be found between two bricks in walls. Anthophora retusa looks like a small, dark bumblebee, but she has orange-coloured hairs on her hind legs. In the UK this bee appears in the early spring.

Honey bees

On the left is the honey bee. It is not nearly as hairy as the bumblebee, and is usually smaller.

Wasps

On the right is a wasp. They have the same colouring as some bumblebees, but they do not have much hair. There are various species around the world that have the same yellow and black striped colouring, and they range in size from 10 - 30 mm long.

Wood wasp, horntail

Wood wasp or horntail

On the left is the wood wasp or horntail. It has similar colouring to some bumblebees, and its speedy flight make it hard to see that it is not hairy. These insects do appear very frightening, but they are completely harmless. They range in size (depending on sex and species from 12 - 44 mm long.

hoverfly

Hoverflies

Left and right are hoverflies. Some of these are excellent mimics of bumblebees. One (I don't have a photograph yet) is very furry and can even buzz like a bumblebee, but all of them have just one pair of wings.

Criorhina berberina
long-tongued fly drinking nectar

Flies

On the left is a fly from the USA with a very long tongue (the black thing between its front legs) drinking nectar. Its behaviour is similar to bumblebees, but it has far fewer hairs, and only one pair of wings. This photograph was sent in by Leona M. Goettel, who has kindly given her permission for www.bumblebee.org to use it on this page.

Hemaris officinalis

Moths

On the left is a moth found in North America called Hemaris officinalis, the snowberry clearwing. Because of its hovering habit whilst drinking nectar it can be mistaken for a bumblebee. There are a number of similar day-flying moths such as the bumblebee hawkmoth in Europe which are commonly mistaken for bumblebees, mainly because they are so difficult to get a good look at. They have a wingspan of 3.2 - 5.0 cm.

Sesia apiformis

Above is Sesia apiformis, the hornet clearwing moth. Because of its colouring and clear wings it is sometimes mistaken for a bumblebee. It has a wingspan of 38 - 48 mm.
