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.


Thanks! Makes sense.

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?

Thanks Alex, interesting point you mentioned.
I would love to know what species of leech I met there though :?

Dear Guillaume,
sorry I´m not fit in leeches.
It might be Erpobdella spec. (Erpobdella octoculata is very common in Germanycheck - for the eyes).
It don´t look like Hemiclepis, Haementeria, Piscicola .
Greetings Alex
