This is
Scatella tenuicosta, not
stagnalis. It is the commonest glasshouse species. In fact
stagnalis has never been found in glasshouses, despite the many references to them there. I am preparing a paper on this subject (in my "to do" pile! :o).
The distal wing spot is often shaped like an hour-glass in
tenuicosta, but is either square or rounded in
stagnalis, which is a bigger, browner species as well.
