Spent a lot of time watching swarms of midges and other insects, mostly while drying after yet another bath. Naked people have an unsatiable interest in the endeavours of insects, as it turns out. Not much learned, except confirmation that midges are indeed very sensitive. It might be more helpful to think of midges as lumps of matter that materialize out of nothing, instead of lumps of matter that move according to some unknown law. They always seem to appear in calm, humid, warm places, but nobody has ever seen them coming.
