As far as I can gather this really hasn't been a good year at all for
the social wasps including Hornets in much of France . It’s that bad first 6 months
to the year again that caused all the problems, cold nights and too wet,
especially bad for the ground nesting wasp species.
Now I guess a lot of people will be happy with this as they
are a group of insects that people generally love to hate, or if hate’s too
strong a word, dislike intensely. Broadly I can understand why, they are known
to sting in certain circumstances and very few people actually enjoy pain or the
reaction that can sometimes follow, swelling, itching, soreness and so on
although in reality most people are rarely stung or experience very strong
reactions if they are.
Of course as usual the media plays a largely negative role
with "shock stories" should someone actually die, usually as a result of
disturbing a nest and receiving a large number of stings, or perhaps because
they are one of the relatively rare people that go into Anaphylactic shock from
wasp stings. However when looked at objectively what we find is that wasp
stings are just about at the bottom of the list of events likely to cause a serious ongoing health problem or death.
If I take for convenience the official cause of deaths in 2010
for England and
Wales which totaled 493,242 registered during the year we find that only five
people suffered fatal “contact with hornets, wasps and bees".
BUT a total of more than 3,600 people died in falls,
including 50 who slipped on ice or snow.
99 people were killed in falls from beds, 52 in falls from chairs, 655
fell down flights of stairs and 13 died accidentally after falling off a cliff.
Needless to say you will have gathered by now where I'm going and that I quite
like wasps and hornets and I would like to think not without good reason.
Top of the list is that they kill tons and tons of other
insects throughout a full season to feed their larvae. The insects chosen will
vary according to the species and to what are available but will include lots
of aphids and other so called garden pests. Beats using pesticides and promotes
balance.
Secondly they are a food source themselves for other
creatures. A couple of good examples are the Honey Buzzard, Pernis apivorus, that will
rip apart perhaps a 100 or more wasp nests during the summer months to feed both themselves and their young with the larvae, and the Bee-eater
Merops apiaster will also take large
numbers of wasps and hornets among other insects to feed themselves and their young.
A lack of wasp nests will lead to Honey Buzzards digging out
Bumble bee nests which is something to be avoided if at all possible.
So perhaps wasps and hornets aren't really that bad after
all?
