Summery wildlife garden

A walk around the lush meadows of the wildlife garden yielded a number of invertebrate sightings. The day flying Six Spot Burnet moths, with their bright red-pink and dark metallic wings feasted on the knapweed (above).
A Meadow Brown feeds on the abundant oregano.
I caught a Small Skipper and a Six spot burnet on knapweed.
These are two shots of Small Skippers, one of my favourite butterflies. The way they carry their wings, held at different angles, instead of pressed together like other butterflies, is quite characteristic.

On the grass, there were many nursery webs of the nursery web spider Pisaura mirabilis. With a bit of patience, the guarding females could be spotted on or under the tents. She guards the eggs, and then the spiderlings which hatch inside the nursery web and remain in it for a few days.
A female Pisaura mirabilis.
My first summer generation Comma Butterfly.
And the first Gatekeepers. These two weren't wasting any time and were mating
Male Gatekeeper.
A Ringlet sat atop a ragwort inflorescence. Once I got closer, I realised the butterfly was dead, prey for a spider that often builds its web under flowers, Enophlognatha ovata.
This large hoverfly is one of my favourites, Chrysotoxum festivum. I often see a male hovering over the pond in the wildlife garden.
I took this shot on the 9th of July this year of the hovering male.
And in the oregano, a cuckoo bumblebee, Bombus ruderarius rupestris which parasitizes the similar looking Bombus lapidarius.

Marmalade fly ovipositing

Aphids are everywhere now, under tree leaves, on herb stems and on tender bush shoots. But they have many enemies. Amongst them, many hoverfly species are busy egg laying, carefully choosing their oviposition sites to be next to rows of fat aphids. This is my first photo of the year of a Marmalade Fly, Episyrphus balteatus: a female laying on a Wood Avens stem full of aphids. It was the only shot I took before she flew away. Soon their voracious larvae will be munching aphids away.

Zebra-striped hoverfly

It is unfortunate that not many hoverflies have English names - only the Marmalade Hoverfly and the Large Narcissus Fly come to mind. However, this large hoverfly, Scaeva pyrastri, with its very distinctive bold black and white abdominal pattern and hairy eyes could be named the Zebra-striped hoverfly, as suggested by John Wall in BugGuides. It is a high summer hoverfly, I have only seen it in July and August, and is a regular immigrant from the continent, and comes here to breed. It can feed on both tubular, deep flowers, like Red Valerian, Verbena bonairensis, Agapanthus and Lavender and also on flat ones like Fennel. Today's was the first of the year.
