Wasps can be useful as they feed their grubs on insects and flies
and help pollinate flowers.
Wasps are related to
bees and ants. There are seven species in Britain including
hornets. The two species most commonly found are the Common Wasp
(Vespula vulgaris) and the German Wasp (Vespula
germanica).
Spring
The queen emerges
from her winter hibernation and begins to look for a suitable
nesting site. When she has found one, she begins to build her nest
with a papery material that she makes by chewing small pieces of
wood with saliva.
The nest consists of a canopy under which there
is a stalk to which tiers of cells are attached.
The openings of the cells face downwards and, as
she lays an egg in each completed cell, the queen sticks it in
place. When the grubs have hatched from the eggs the queen will
feed them until they are ready to pupate.
Summer
By about the beginning of July
enough adult workers have emerged from the cells to take over the
duties of nest building and feeding the grubs. The queen then stays
in the nest and devotes herself entirely to egg laying. Eventually
a colony might consist of several thousand wasps.
Autumn
This is the time of year when males
and young queens are produced, the males fertilise the queens and,
with the remaining workers, die. The queens fly off to find
hibernating quarters in dry protected places such as
sheds.
Winter
The queens hibernate
throughout the winter to emerge in the spring. Old nests are not
reused but a specially favourable site may be used again to build a
new nest.
People are often frightened of wasps because of
their painful stings, but in fact most species rarely sting unless
disturbed or annoyed.
Treatment of Stings
The effects of wasp
stings usually last only a few hours. A soothing lotion containing
calamine may be helpful in reducing pain.
Medical assistance should be sought for stings in
the mouth or throat.
An extremely small number of people are very
sensitive to wasp stings. They will always need immediate medical
attention.
