I have always been fascinated with the differential periodicity Schistosoma
cercariae exhibit when they emerge from their snail hosts and concentrate in
streams and watering holes at times corresponding to the peak activity periods
of their definitive host populations. Some of this is briefly reviewed in
Soulsby (1982), but i have also seen some papers in the Transac. of the Royal
Society (late 80's). Hope this is helpful.
