Letter: Wasps need saving too

SIR - A few days ago I did something I have never done before: I saved a wasp. Scientists are telling us that insects are in sharp decline, worldwide, as much as by three quarters of what they were. This is serious because we need insects to pollinate our food plants. Also, there is a serious unbalance of nature now. When I was a child I remember that the windscreen was spattered with dead moths when we drove at night, but there seem to be too few to do that nowadays. Now we have found out that a wasp nest is being built just near by but we won't do what we used to do, and kill the lot off!
