I already had a question about dealing with mosquitos: Really virulent mosquitos - dealing with them and their bites
But this question is about whether they really do vary in virulence and toxicity. A few people in the other question suggested I am naturally a target and react badly to bites. However:
- I haven't in other locations had such big reactions, I get nasty lumps but not swellings several centimetres across
- My wife gets even worse reactions, e.g. her whole calf went red and swollen from a single bite - and I currently can't clench my fist because one bite made it swell up!
- several other people, including a gardener and a tree surgeon who both deal with such things all the time, have commented they react particularly badly when working in our garden
Interestingly this summer I am reacting differently than this time last year - bigger swellings but less itchy and no weeping wounds. This may be due to the difference between midges and mosquitos.
So - are there a large number of sub-species prevalent in the UK (NE UK specifically) or can a given population become more nasty for some reason?
