For me, the wasp life cycle is interesting. But why digress into the subject of wasps?
Well, although this website is about bees, it is, I think, relevant to add a little information about wasps. For one thing, it is believed that bees descended from sphecoid wasps.
whilst many people do not like wasps, it is worth remembering that wasps are pollinators, and they also help to control
aphids and other insects known to eat garden crops.
There are a number of similarities between some wasp and bee species.
In fact, the wasp life cycle is short, and some wasps have similar life cycles to bumblebee or certain solitary bee species.
This page provides a broad description of the wasp life cycle for social and solitary wasps, but there are differences between species.
Wasps are found in a variety of habitats depending on the species. The common wasp and German wasp are frequently seen around gardens and parks.
Social wasps live in colonies within large nests, (which tend to resemble paper), and as with social bees, the colony is dominated by a queen.
The wasp queen lays all the eggs, whilst worker wasps tend to the nest and colony duties, such as caring for eggs and larvae, nest building, foraging for food and defending the nest from attack, however, the queen must do the work in the early stages of establishing her colony.
Hibernating, wasp queens
emerge during the spring. They will have mated with males the previous
year, and are thus fertilized. Their first task is to begin building
their nests, usually from bits of dead wood and plant material which is
chewed to form the papery walls. Inside the nest, the queen also builds
egg cells, where the eggs are laid and where larvae can develop into
worker wasps. Once sufficient larvae have developed into mature wasps,
the queen will no longer forage or engage in general nest duties – all
of which will now be left to the workers, and instead, she will devote
her time to laying more eggs.
Eventually, males and new queens will be produced. The queens will leave the nest, mate and hibernate until the following year. Meanwhile, the rest of the colony will die, as is the case with bumblebee colonies. The old nest will not be re-used, whereas in some cases, bumblebee nests might be used by future generations of bumblebees but only if the site is in suitable condition.
As with bees, most wasps are solitary.
Solitary wasp females emerge
from hibernation and are responsible for constructing their nests,
laying eggs and providing the larvae with food. Solitary wasps are
generally not aggressive, and it is said that they are far less likely
The wasp life cycle is such that they are, on balance, beneficial in the garden, since they take young aphids and caterpillars that eat crops in spring, and they also pollinate plants. However, they also will eat some soft fruits, and they will attack bee nests, usually hunting for larvae. However, I have many times witnessed bees and wasps foraging on the same shrub.
Nature is not wasteful, and
whilst it is easy to be critical when one creature preys on another, it
is important to remember that mankind is not only a predator, humans
are also the biggest threat to most creatures due to their activity on
the environment, and sometimes shockingly, and wastefully so.
Note that some bees and hoverflies can be wrongly mistaken for wasps, although when viewing images closely, the differences may seem fairly obvious for some of the species.

It should be noted that there is, however, tremendous variation in the appearance of wasps, and of course, hoverflies as well as bees!
