Today there is evidence of several damselflies emerging. The leaves of some of the marginal plants have the empty larvae cases ( exuvia) of the nymph, left behind after it climbs out of the water where it has spent the last year and emerges as a damselfly. As the nymph spends at least a year developing underwater before emerging, we must assume that the eggs arrived on the vegetation brought in.

Useless fact for Monday - the empty case of a dragonfly etc is called an exuvia. Daft the things I remember. I noticed Dacathlon had pond dipping nets for sale for just 2€ so I might treat myself and do some dipping in our little pond.
