Ticks, mosquitoes and midges
Three pages, and the three answers are not the same kind of thing. For ticks we say only whether they are out, with no number. For mosquitoes there is a number that changes with the place. For midges there is a number whose biggest limit — wind — we do not measure at all, and that is worth knowing before you read it.
Ticks
One species that matters, two seasons in the year, and Lyme disease. What our forecast says — and why it gives no number.
Mosquitoes
A nuisance rather than a danger here, and the reasons why are worth knowing. Where the number comes from and what moves it.
Midges
The Highland midge decides what a summer day in the west looks like. It breeds in peat, not in water, and it is stopped by wind we do not measure.
