This makes travel in the tropics in the wet something of an ordeal. The rain buckets down, the dirt roads turn to slush or treacle or both, vegetation grows a centimetre a second, and insects multiply ecstatically to distribute the increased load of pollen. So the moment the rain stops washing you down, the insects settle. It seems to me that even those goggas that don't require a blood meal will take an experimental bite just to see if you're edible. In no time legs and arms and neck are interestingly blotchy with varying sizes of munch-marks, which vary in intensity of itch.
Camping becomes a little more challenging too.
We have a system of erecting a tarpaulin over the site to keep the rain off, a tarpaulin under our feet to keep the mud out, and a little verandah tarp over the tent entrance to facilitate a dry retirement at the end of a soggy day. And in the tropics water turns into mud as you look at it. It might not be impossible to stay clean and dry camping in the wet season, but it is very unlikely. Nevertheless, there are advantages. For instance washing up after dinner is a breeze.
