First sighting…

…apart from a few milliseconds of an adult, before it vanished deeper into the Pond.  What I don't know - Has it grown that much over winter - OR - is it 2+ years old.

Extra.
On of my many attempts was perfect - UNTIL - s/he leapt as I clicked.
Result - fuzzy Frog, clear mit.
Cure. -  Sharpen Frog as much as poss.  Blur the mit a teeny bit.
It's the best example I've ever had of how long their legs really are, at full stretch.  Imagine a human High-jumper with that ability... which is, basically why I kept it.
