Over the Pond

I like to leave overgrown corners for wildlife but it’s time to cut back the nettles, hogweed, blackberry and sorrel behind the pond before they take over.

Nettle Rust Fungus

Orange stipples of rust fungus, Puccinia urticata, have caused a swelling on a stem of stinging nettle. This fungus has an alternate generation which grows on sedges, which doesn’t result in swellings. This nettle was growing next to a pendulous sedge, Carex pendula, behind the pond.

Harlequin Ladybird

When I started my Wild Yorkshire blog, harlequin ladybirds had yet to be recorded in Britain. The first records were in 2004 but now they’re our commonest ladybird.

Dozens of them spend the winter gathered snuggly in the narrow gap between our back bedroom window and its frame. There’s a great variety in their markings. A harlequin might have red spots on black or black spots on red. They can vary from having zero to as many as 21 spots.

Flea Beetle?

I’m going for flea beetle, possibly Altica lythri, as the identity of the small beetle I found on a sorrel leaf.

According to the ukbeetles.co.uk website: ‘Altica species are easily recognized by the 11-segmented antennae’.

The UK Beetles website describes it as a common beetle of parks, gardens, wasteground, dunes and salt marsh. The food plants of its larvae include willowherbs, loosestrife, enchanter’s nightshade and evening primrose.

Brown Rat

The rat jawbone may be the remains of a fox kill but the foxes haven’t succeeded in eradicating every last brown rat in the area.

We had one of those sudden drenching showers this afternoon with hailstones falling amongst the heavy rain. As I walked across the back lawn later it was squelching underfoot. The run-off noticeably topped up the pond and it will have refilled the water butts attached to the fall pipes from our roof.

The local rat burrows were probably flooded too as we saw a large brown rat run across the patio, only to change its mind and run back again a minute later. It was the first we’ve seen for months, if not years.

Harlequin Ladybird

A map on the Harlequin Ladybird Survey website shows how this North American species, introduced to Europe in 1988, has spread from the south-east of England. From a couple of records in Yorkshire in 2003-2004, it has now been recorded across most of the county, with the exception of parts of the Dales, the North Yorks Moors and the Wolds. It’s apparent absence here may be the result of there being fewer people to record them.
