I literally dipped in and out of Cosmeston on 2 May, for a quick look at the dipping pond to see if I could spot any Water voles. I dipped on the voles but I did see Ma Mallard and her two gorgeous ducklings, and a gazillion tadpoles.

11 May  I needed to stretch my legs after spending the previous day sorting out after my birding trip so off to Cosmeston I headed. I came in from the north end via Old Cogan farm, where a pair of Swallows was sitting on the wires. I suspect they nest in the old barn as I see them there often over the summer months.

Apart from those Swallows, it was quiet on the bird front and, as a cool wind was blowing, there were no butterflies about either. So, I took lots of photos of newly blooming wildflowers  …

While doing that, I found an interesting little critter mooching around on some leaves (it looked like a weevil without a long snout but I haven’t positively identified it), and I spotted my first cuckoo spit of the season (I just know you’ll be delighted with that find!).

15 May  A brief walk through on my way home from Lavernock. I wandered along the edges of Sully brook and then, once again, stopped for a few minutes at the dipping pond. The bad news was that mother Mallard only had one duckling remaining – fingers crossed it makes it to adulthood. The good news was that I saw my first damselflies for the year – both Azure and Large reds were out in numbers.

17 May  I passed through Cossie again, this time on my way home from Sully. A Common whitethroat was showing well in the reeds near the cafe, and a Coot was shepherding her three young offspring around the west lake. The chicks were well developed, which bodes well for their survival.

20 May  This time my 3-hour mooch was all concentrated at Cosmeston. I went early to avoid the Sunday crowds and the scorching sun, and walked the east and west paddocks from one end to the other and back again, along the various trails. I was looking particularly for orchids but saw only leaves, a few with the stalks of flower buds just emerging, and for butterflies. The Dingy skippers and Common blue butterflies were out in good numbers, and it was a pleasure to watch them flitting to and fro.

24 May  I went early again to Cosmeston but not early enough, as the rain came in almost as soon as I arrived and I didn’t have a coat with me. I lingered long enough to enjoy the glorious Hawthorn blossom that covers the hedgerows like summer snow, before striding quickly homewards.

All spit and no cuckoo

Cercopis vulnerata, cuckoo spit, froghopper, red-and-black froghopper, spittle bug

What an intriguing insect this is! I’d heard of spittle bugs, of course, but didn’t really know anything about them until I started researching their story to go with my photos. Briefly, here’s what I’ve discovered …

160630 Red-and-black Froghopper (1)

The Red-and-black froghopper, scientific name Cercopis vulnerata, spends most of its life as a nymph living around the roots of trees, and the adults only appear above ground for a few short weeks in the summer.

So many British insects are hard to identify but the colours of this froghopper make it truly unmistakable – good news when it’s looking for a mate. Please excuse yet another voyeuristic photo of insects in copula!

Now comes the weird bit, the ‘cuckoo spit’, so named because it appears about the same time cuckoos reappear in Britain and can be heard broadcasting their characteristic call, though why the spittle is referred to as their spit escapes me. And it’s not really spit at all – it’s produced by the tiny froghopper nymph to protect itself from drying up and as a place to hide from predators.

This cute little nymph actually mixes a fluid from its anus with a secretion from its abdominal glands and then blow bubbles into the mixture from a valve on its tummy. (And I touched that stuff!) After hanging out in its bubble sac for a while, the nymph heads underground, where it sheds its skin several times before changing into its red-and-black adult form and starting the process all over again.

Oh, and the froghopper part of its name comes from the way it imitates a frog by leaping away from danger, though I’ve never seen one do that. Maybe my camera and I don’t look all that dangerous.
