In my garden pond, it seems the density of leeches is much higher than usually. Can't draw any conclusion, but at least remarkable.

A lot of subtle things. The loose hanging belly is also (very) rare in males and typically a post-birth thing.

phoresie (using other animals for transpotation...) between leeches and amphibians seems to be quite common. At last I have observed it between Epobdella and Pelopylax ridibundus ca. 50m away from a lake.
Maybe one fertilised leech came with a newt?
