Butterflies in Tuscany

Common Blue [L’icaro o argo azzurro] (Polyommatus icarus) on Lavender beside the swimming pool of the lovely agriturismo farm, Rocca di Cispiano, where we stayed in Chianti. Species names are shown in English [Italian] and (Latin).
Pool area: not an obvious place for butterflies, but the clever planting of a Lavender border made all the difference

Scarce Swallowtail [Il podalirio] (Iphiclides podalirius), a large butterfly with a distinctive sailing flight, taking nectar beside the pool
Silver-Washed Fritillary [La pafia o Tabacco di Spagna o Fritillaria] (Argynnis paphia), a handsome and distinctive species

Tuscan landscape (Chianti): hilltop farms, Vines (bright green rows), Olive trees (blue-gray trees in rows), low mixed maquis (macchia mediterranea) forest, Cypress trees on left skyline

Nine-Spotted Moth [La fegea] (Amata phegea) frequently visited the lavender border and other flowers. It was once also found in England; Chris Manley suggests that global warming might allow it to return (a possible silver lining to that cloud).
Brimstone [La cedronella] (Gonepteryx rhamni)
Hummingbird Hawkmoth [La sfinge del galio o sfinge colibrì] (Macroglossum stellatarum), darting from flower to flower each time just before I managed to focus the little camera …

Bee-fly (neither a bee nor a butterfly) half-hovering to take nectar, making a particularly loud buzz

Meadow Brown [La Giurtina o Maniola comune] (Maniola jurtina)
Red Admiral [L’atalanta] (Vanessa atalanta). It has  a chunk out of its right hindwing, showing it survived an attack.
The enormous, fearsome, but non-aggressive Mammoth Wasp, [La vespa mammuth] (Megascolia maculata), on Wild Artichoke. Presumably its sting would be serious but I can’t find any record of people being stung by this peaceful insect.

The bushes by the pool attracted this Southern White Admiral [Il Silvano azzurro o Piccolo silvano] (Limenitis reducta)
Swallows  [La rondine] (Hirundo rustica) swooping over the pool at sunset. Many pairs nest in the farm buildings; there were two active nests inside our porch.

Perfect butterfly habitat a short walk from the agriturismo: meadow grass by Olive groves with Scabious (blue) and St John’s Wort (yellow). There’s a tiny Queen of Spain Fritillary in the picture!

Sloe Hairstreak [Satiro dell’acacia] (Satyrium acaciae)
Swallowtail [Il macaone] (Papilio machaon); this one at Brolio castle, but there were many near the agriturismo too
Queen of Spain Fritillary [La latonia]  (Issoria lathonia) on Scabious
Clouded Yellow [La crocea, La limoncella, Il postiglione] (Colias croceus) pair in nuptial flight
Marbled White [La galatea] (Melanargia galathea)
Probably Eastern Burnet Moth [La carniolica] (Zygaena cf carniolica) on Scabious.

Zygaena cf carniolica taking flight. The brilliant red underwings give a strong and honest warning signal of the insect’s inedibility.
Eastern Dappled White [L’ausonia] (Euchloe ausonia)
Olive Grove and Spanish Broom. Butterflies skittered about the flowery meadow below the trees.

Wall Brown [La megera] (Lasiommata megera)
A lizard, probably the Common Wall Lizard [Lucertola muraiola] (Podarcis muralis) given its dark chin, scurried along the wooden rail at the edge of the pool area.

Great Banded Grayling [Circe, Satiro circe, Sileno] (Brintesia circe)
Dingy Skipper [Tagete] (Erynnis tages). There were Large Skippers about too, but their habit of perching on slender waving grasses made photography hopeless.
Painted Lady [La vanessa del cardo] (Vanessa cardui)
Spotted Fritillary [La didima] (Melitaea didyma)

Some rather fine wasps apparently attempting to mate

Although it was a bit late in the season for them, we saw half-a-dozen fireflies in the woods by the strada bianca (unmetalled road) and among the olive trees, half an hour or so after sunset.

I made no attempt to photograph birds, but a Hoopoe flew over the pool, and Turtle Doves cooed nearby. A Cuckoo called from far across the valley; a Song Thrush sang; a Green Woodpecker gave its laughing cry. White Wagtails flew up to the roof, and Italian Sparrows hopped about. Goldfinches twittered in the trees. A Sardinian Warbler raced for the cover of the trees, its black crown conspicuous; a Melodious  Warbler sang from the woods. In the night, an owl called, it could have been a Scops Owl. And of course, Cicadas buzzed and Bush Crickets chirped all day long.

Of Hoverflies and Bush Crickets

An English Summer is, as the saying goes, three fine days and a thunderstorm. Or, going out with sunhat, suncream, sunglasses… and a pullover and raincoat, just in case. Today it started out cold with a chill north-north-easterly wind, but quietened down and became rather too hot to work comfortably.

A tree had fallen across the glade in the Gunnersbury Triangle where the beekeeper is going to station one of her hives. I soon threw off my pullover, and my rainproof jacket never left my rucksack. The soft willow wood was no trouble to saw up, and I dragged the branches to the dead-hedge without much effort. A lot of small holm oak, an invasive alien species from the Mediterranean (think Ligurian coast) has sprung up from old stumps, so they joined the pile.  A Blackcap sang to me while I worked.

The butterfly transect revealed very little, though some Commas are encouragingly laying eggs. As for other insects, several species of hoverfly, from tiny and slender to large wasp mimics and a fine one largely black, perhaps a bee mimic, were active. They hover, perch and sunbathe, or dash and chase each other (specially the large black ones) aggressively. I had fun trying to photograph one actually in the air, you can see the atmospheric but not very useful result above. It does give something of an idea how much they whiz and dash about, hovering always on the qui vive.

Ragwort is getting more and more abundant on the reserve; today, Helen spotted some tiny (probably first instar) Cinnabar Moth caterpillars on one of the plants; an adult visited me while I worked.

The Peacock Butterfly caterpillars of last week seem all to have pupated in hiding somewhere; there are quite a few younger ones still on the stinging nettles, so there will be at least two lots of adults.

We found a Knot Grass moth caterpillar (a Noctuid moth) on a bramble. It is hairy and aposematic, with brown hair but without the four long brown ‘shaving brush’ tufts of the Vapourer moth caterpillar (a Lymantriid or Tussock moth), which we’ve also found here.

But perhaps the insect I was happiest to see was this young Bush Cricket, resting on a flower for no particular reason, and taking a risk as its fine spotted green camouflage was totally compromised by its white and yellow flowery background. It must be the first one I’ve seen this year.

I have always loved natural patterns. The bark of this Aspen tree looks almost as if it encodes symbols in some cuneiform notation.

Not much to see at this time of year?

After the brief heatwave it feels like March again. In the Gunnersbury Triangle nature reserve, willow buds are starting to open but only the evergreen trees like the native yew and holly, and the invasive holm oak (from the Mediterranean) are in leaf. Not much to see, then? Not a bit of it.

In the leaf litter under the forest canopy, a large and handsome white slime mould was spread out, draped over some twigs in a fine shiny film. In detail its surface seems almost fractal, full of rounded holes at different scales like a Sierpinski Triangle if you know what one of those is. The individual cells – I’d almost call them animals – of the slime mould signal to each other with a chemical (AMP), which causes them to aggregate; they slowly ooze along like amoebae, eventually forming fruiting bodies rather like small fungi. It’s an extraordinary process, and in an odd way quite beautiful.

Leaf Miner, probably Ectoedemia heringiella on Holm Oak

Meanwhile, the large holm oak by the picnic meadow looks utterly extraordinary, something like the horse chestnuts that have been attacked by plagues of leaf miner moths. Almost every leaf of the holm oak is scarred yellow and brown with the wandering trails of the moth caterpillars, making the tree look multicoloured and very badly battered. This is probably the work of Ectoedemia heringiella, according to the RHS.

Many of the leaves also have squarish brown furry patches (a filzgall or erineum ) on the underside; the leaves are naturally fluffy, with a tiny gall mite, Aceria ilicis, causing overgrowth; the thickened, darker hairs are too tough for the insect to eat, so the plant’s reaction works as a defence.

And that is not all; there are also a fair number of much larger pupae, probably of another moth species, wrapped in partly-rolled leaves, tied up with silk threads. We used to think of the holm oak as a useless non-native species with no pests or predators: not any longer, it seems, though at least the leaf-miner is a recent arrival itself.

Down at the pond, there are masses of frogspawn; at least a dozen large frogs, with at least four mating pairs, were responsible. When we came over the mound they must have seen us as there was a remarkable amount of splashing; even in amplexus they are capable of emergency diving: this is just as well, as much of the weed and reed has been cut during the winter.
