Dangling Marsh-lover

Yes, another find from Ashdown. I think it's the first hoverfly (Diptera order, Syrphidae family) on the blog. I was looking at the excellent Hoverfly Recording site and according to them 106 hoverfly species have been recorded in my postcode (BN7)! This is Helophilus pendulus, one of the commonest species in the UK. Besides being important pollinators, hoverfly larvae are big aphid-eaters, making them a valuable friend in the garden.

The Streakt Cloudy Hog

Having done the Streaked Golden Hog (aka Small Skipper) I realised I hadn't done this beauty, photographed during my extremely productive sojourn to Ashdown Forest back in July. It is the Large Skipper, Ochlodes sylvanus, the commonest of our eight Skipper family (Hesperiidae) butterflies. It used to be known as The Chequered Hog or Streakt Cloudy Hog - much better names if you ask me, especially the latter.

Roesel's Bush-cricket

Found on the same day as the Mottled Grasshopper, this is a bush-cricket: Roesel's Bush-cricket, Metrioptera roeselii. You can tell a bush-cricket from a grasshopper easily: the latter have long antennae, usually longer than their bodies. Also the females have long, scythe-like ovipositors. Roesel's Bush-cricket has a cream edge to the prothorax. It is also an organism that is spreading in the UK as a result of global warming.

Small Purple-barred

Another find from the Ashdown haul. This is a Small Purple-barred, Phytometra viridaria, whose larva feed on Common and Heath Mildwort which is plentiful around where it was found.

Goldenrod

Having re-discovered my photos taken on the camera (or possibly Ian's camera) there are lots of things from our trip to Ashdown Forest that I didn't use nearer the time. This is one - a rather striking member of the Daisy family, about 70cm tall, with delicate flowers in a tight raceme. It's Goldenrod, Solidago virgaurea and at the time I didn't recognise it. The upper leaves are quite distinctive and differ from the basal rosette of long obovate slightly toothed leaves.
It is found in a range of habitats: dry woodland (where it can be an Ancient Woodland Indicator), grasslands (as here), cliffs and dunes.

Mottled Grasshopper

You will have to zoom in or take my word for it, but this is a Mottled Grasshopper, Myrmeleotettix maculata. You can tell because of the distinctive club-tipped antennae (lacking a white tip). This was take up on the heath in Ashdown Forest back in July.

Great Cormorant

Crossley ID Guide

Plenty of these in the Ouse Valley. They nest colonially on a tiny island in a small lake made by the owner of a local farm. The vegetation has been ruined through shear numbers. The Great Cormorant, Phalacrocorax carbo, is not to be confused (but often is) with the Shag, most notably by Christopher Isherwood in his poem The Common Cormorant.

Creeping Feather-moss

The problem with mosses is that it's very difficult to show them well in photographs. I was going to take a photo through the microscope but it didn't come out well and wouldn't be that instructive. This is a moss collected growing on the site of a WWI sea-plane hangar at Newhaven. (Well it's not the actual moss but the same species.) This time keying it out was a bit simpler - Creeping Feather-moss, Amblystegium serpens. It's very common and usually found on living or dead wood, but also on soil and stones, the bases of walls and tarmac.

Rook

I've noticed that some Rooks, Corvus frugilegus, are already nest building and possibly even sitting on eggs. It's such a mild winter that this can happen, although a cold snap can be catastrophic for the young if it is prolonged after hatching.

Black-Headed Gull

There were plenty of these around today down at Newhaven and roosting on the Lewes Brooks RSPB reserve earlier in the week. The 'black' heads of the Black-Headed Gull, Chroicocephalus ridibundus, is in fact chocolate brown and only seen in the breeding season. They have black wing tips which distinguishes them from the similar Mediterranean Gull. The latter also has a heavier bill without the black tip and a truly black hood which extends further down the nape.

Purple Sandpiper

Saw about eight of these little chaps milling about on the lowest parts of the east arm of Newhaven harbour. They are funny to look at with their short legs and dumpy bodies. The slightly down turned beak and beady eye gives them a somewhat shifty appearance. There's something incongruous about their habit of pootling about where the mighty ocean crashes into the land right next to them. The Purple Sandpiper, Calidris maritima, isn't particularly purple even in its breeding plumage. It breeds on Arctic islands and most don't come as far south as Sussex. Their loss from this county is possible with continued global warming, although some regularly overwinter in Portugal.

Pointed Spear-moss

Ciarán Byrne @kiwibyrne  

This grows (abundantly) in my lawn and I've tried a couple of times before to identify it. The last time was probably February, which was probably the last time I'd got the moss book out. It was a eureka moment to finally pin it down but not before I'd arsed about in the acrocarp keys: what an idiot! It's a pleurocarp of course. That's what happens when you don't know what you're doing and you don't start at the beginning.
Anyway, having dissected it under the stereomicroscope and looked at the cellular structure of the leaf under the compound microscope, I could have identified it without either if I'd just followed the key.
It is Pointed Spear-moss, Calliergonella cuspidata. I've nicked the photo from Ciaran Byrne's twitter feed. Ciaran is an amazing ecologist and prolific tweeter. I would urge anyone with Twitter access to follow him.

Floating Sweet-Grass

This is Floating Sweet-Grass, Glyceria fluitans, doing what it says on the tin. It is common in slightly nutrient enriched fresh water ditches where it forms rafts, as seen here.

Watercress

This is Water-cress, Rorippa nasturtium-aquaticum, which is common in the ditches around the reserve. The Latin name gives away its culinary comparison with nasturtium - a peppery flavour. Care should be taken if eating wild Water-cress as it can harbour the cyst stage of liver-fluke, a parasite of sheep and cattle. Only take it from a stream with running water where there are no grazing animals.

Broad-leaved Pondweed

It's been so mild that there is quite a bit of growing going on out there. This is Broad-leaved Pondweed, Potamogeton natans, growing in one of the many ditches. It's only in this ditch that I've come across it, unlike the ubiquitous Lemma minuta. The pondweeds are a tricky group with around twelve species. This is fairly easy to identify because the leaves float and there is often a discoloured joint at the end of the long leaf-stalk.

Black-Tailed Godwit

By Richard Crossley (Richard Crossley) CC BY-SA 3.0 via Wikimedia Commons

I was doing the WeBS survey down on Lewes Brooks RSPB reserve this morning. There was no wind and it was cold but not crisp. Still few wildfowl, just mallards and a handful of wigeon and teal. But the lapwing were there in numbers, around 200 or so, and when the flock was in the air I noticed another bird flying with them. It looked like an oversized snipe but the trailing feet, clear black terminal band on the tail and white trailing edge of the wings showed it to be a Black-Tailed Godwit, Limosa limosa. It is unusual to see a solitary bird and I think this was the first time I'd seen one on the Brooks. The birds in the UK are of the Icelandic race, L. l. islandica. It calls repetitively in flight.
The similar Bar-Tailed Godwit has a barred tail (no, really) and an equally long beak which has a slight curve upwards. The Black-Tailed Godwit has been Red-Listed since 1996 but the numbers overwintering in Sussex have been increasing over the last 20 years with Pagham and Chichester harbours holding around 3% of the national total. 
 

Red Campion

Bizarrely I didn't take a picture of Red Campion, Silene dioica, so this is from the amazing resource that is Wikipedia. Red Campion is a bit more widespread than White Campion, growing up to 1000m altitude whereas White Campion is confined to lowland areas, especially those with calcareous soils. It grows at the back of the pond in the garden.

White Campion

Another plant I can't believe didn't get blogged before. The campions, Silene, are a familiar genus. Red Campion is probably best known, but White Campion, Silene latifolia, is also widespread. It can be confused with Bladder Campion and, by the sea, Sea Campion, which both have white flowers. White Campion is usually very hairy. It is also dioecious - having separate male and female plants.

Japanese Knotweed

This is the dreaded Japanese Knotweed, Fallopia japonica, introduced from Japan in 1825 and causing problems ever since. In my native Swansea it was a spectacular problem. Entering the city by train you passed through seemingly endless groves of it. It is listed by the World Conservation Union as one of the world's worst invasive species. In Australia it is actually illegal to have it growing on your property. This was growing on the edge of Amberley Brooks in West Sussex.

Grove snail

This is a common snail which can have be found with a wider variety of patterns. Cepaea nemoralis is known as a Grove snail or Brown-lipped snail and is a terrestrial, pulmonate, gastropod mollusc. Nice.
