Nymphs and Shepherds

Just two years ago we put the bung into the plug hole of our newly dug pond and let Nature do the rest.

Last summer this Common Hawker Dragonfly patrolled its banks and skirmished with intruders for the territory, occasionally looping the loop with a yellow spotted female of his species who must have gone on to lay her eggs in the water, because look what we just found!

And that wasn’t all — the water is alive with biological activity, a million tadpoles whizz around our pond-dipping bucket, getting in the way and obscuring our view of the newts and myriad nymphs — not so easy to identify in life because most of the pictures are of exuvia (the dried up skins of the nymphs, abandoned by the adults after they emerge).   The harder you look the more nymphs appear and all are interacting — some snapping at passers by, others knocked over by a clumsy water beetle — a microcosm.

Here are a few that my grand-daughter helped sort out and photograph–

The identification is more to do with common things being common and having seen a lot of the adults flitting about last summer — here’s one of them —

Common Blue Damselfly (probably).

Blue and Azure damselflies are tricky to distinguish — especially when they are alive!

And what about our friend Libellulia depressa, the Broad Bodied Chaser, the first Dragonfly we spotted by the new pond (often the first to colonise a new pond, said the book, and they were) —

I think this could be one of his offspring

Fat bottomed nymph -- maybe an early Chaser (Libelullia depressa) or a Darter (Sympetrum spp.)

Please comment if you think I am wrong in any of my identification — I may well be, but you have to start somewhere!

Kissing Frogs

 

Now is the time to look for signs of Spring and here, where there is still snow in the shadow of the hedges, we haven’t seen a bulging bud.  But the birds know something’s up!  They have a sense of anticipation and an irritable awareness of their territory — the robins are scrapping and the chaffinches have started to sing and me?  Well, I go out every morning to look for frogspawn and on the morning after Valentine’s night — there it is!

Something for our newts to eat.

Otherwise things look quite wintery though the moss is strangely spruced up and vibrant.

It’s making the most of the early sunlight before being caste into shadow by the burgeoning verdure that will soon overwhelm it — the uncurling fronds of the ferns  and bracken and the canopy of oak leaves.

And the lichens are looking shaggy after a winter unfettered by the competition and unbroken by the resting bottoms of weary ramblers.

The wild unicorn on Van Hill still has his winter coat and hasn’t started yet to get his new horn when he will hide in the woods like the moss.
