Priorslee Balancing Lake and The Flash

12.0°C > 17.0°C: Much medium / high cloud after a better start. Moderate easterly breeze. Good visibility.

Sunrise: 04:46 BST again

I am having a few days watching birds elsewhere. Back Monday all being well

* = a species photographed today
$ = my first sighting of the species for this year
$$ = my first ever recorded sighting of the species

Priorslee Balancing Lake: 05:05 – 06:05 // 07:10 – 09:40

(145th visit of the year)

Bird notes:
- a Common Peafowl (Peacock) was heard calling from what was the Telford campus site.
- the Canada and Greylag goslings all still present and correct.
- I do wonder whether we are going to get any cygnets this year. The pen Mute Swan was yet again away from the nest site for some while. From ring data she is just four years old and this is likely her first nesting attempt.
- the duck Mallard still with one duckling. *Another duck Mallard located with at least nine ducklings.
- the duck Pochard still here.
- the octet of over-flying Starlings were at a very different time and place to the 14 seen earlier on the "football field". From calls both adults and juveniles involved
- a Grey Wagtail was briefly on the dam-face. It is several weeks since I last recorded this species here.

Around sunrise the sky was the clearest it would be all morning.

Looking to the West the cloud as building.

The camera comes in handy. There is no other way to count the Mallard ducklings and even then, and on high zoom, I am not certain. Nine?

The juvenile Great Crested Grebe from the second brood to hatch. I was surprised to see it dive. Here it is calling for the adult to feed it....

...which it did, dropping a small fish in the water in front of the juvenile, teaching it how to pick up fish for itself.

It is not much fun being a Common Buzzard. Crows and Magpies want you well away from them.

My second sighting this year of a Song Thrush smashing a snail. It was still early so the light is not great. The snail in the thrush's bill looks to be a White-lipped Snail Cepaea hortensis. When the thrush attempted to smashed the snail it dropped off the kerb in to the road. When the thrush picked it up...

...it was back-on to me. The smashed shell is between the thrush's legs...

...and the bill has some sticky bits of snail on it.

I saw several of these Green Oak Tortrix moths Tortrix viridiana on my latest visit to Woodhouse Lane. This is my first around the lake for several years.

Another micromoth species from a difficult group. I am reasonably confident its is a Thistle Root-borer Epiblema scutulana.

An exciting looking insect. It is a female ichneumon but I can get no further than "in the Pimplinae group" from any web site.

Another ichneumon for which I could not get an identification.

This is the sawfly Macrophya montana.

This sawfly is possibly Rhogogaster chlorosoma. There are two other similar species both of which show dark marking on the abdomen that this seems to lack.

And this is an unknown sawfly. As with ichneumons there are very many species, many poorly known and with little literature or internet information.

A hoverfly with no visible means of support. In fact the wings are beating so fast the camera has been unable to record them. The triangular spots on this female suggest it is a Chequered Hoverfly Melanostoma scalare.

With the light at the right angle it is possible to notice that the abdomen of the dagger fly Empis livida is banded.

A "greenbottle" from Lucilia species species group. I cannot see species any illustrated on the web with the dark banding between the abdomen segments.

This was a new fly here for me yesterday. Tubby, all black with orange at the base of the wings and pale feet. It is a Noon Fly Mesembrina meridiana.

A fly species I confirmed for the year yesterday. It is the semaphore fly Poecilobothrus nobilitatus, so called because the males have white tips to their wings which they wave to attract the females.

A very common fly I have had limited success in identifying it. It is possibly Tricholauxania praeusta or similar from the Lauxaniidae group. These are not well illustrated on the internet.

It is some days since I saw my previous Mirid bug Calocoris alpestris here.

A species of click beetle possibly Athous haemorrhoidalis though there are similar species.

 Harlequin Ladybird Harmonia axyridis can be orange-toned or....

...deep red. Both are of the form succinea: all the adults I have seen this year have been of this form.

The ventral view of a Cucumber Green Orb Spider Araniella sp. either A. cucurbitina or A. opisthographa with who knows what in its mouth.

I think this is "money spider" not all of which are basically black with red legs. I still cannot provide an ID.

In the Priorslee Avenue tunnel:

Moths:
*1 Flame Carpet Xanthorhoe designata

Flies
1 cranefly Limonia nubeculosa
1 moth fly Psychodidae sp. [Drain Fly or Owl Fly]
26 midges of various species.

Spiders, harvestmen etc.:
*1 possible Snake-back Spider Segestria senoculata
1 unidentified spider

A moth at an odd angle but I decided against standing in the middle of the Wesley Brook for the best angle. It is my first Flame Carpet Xanthorhoe designata of the year.

My second attempt to photograph this spider and once again Obsidentify is 100% sure it is a Snake-back Spider Segestria senoculata. Perhaps it is.

The Flash: 06:10 – 07:05

(143rd visit of the year)

Bird notes:
- I think the number of geese varies from day-to-day at least in part as once they have had breakfast they climb on the island. I do not count those that are already hidden on the island when I arrive.
- six adult Mute Swans. One, clearly a cob, was chasing what was likely #5 with the four that have been here at least 10 days left alone. These four behave as a pair and a pair that are not speaking – often close but not that close.
- the duck Gadwall seen.
- no Tufted Duck.
- a previously unseen brood of two were the only juvenile Coots I noted. The overall total was down also.
- only one Great Crested Grebe noted.

Bird notes:
- a Common Peafowl (Peacock) was heard calling from what was the Telford campus site.

One of the Greylag Goose goslings looks almost grown-up. The wing feathers need to grow more before it will be able to fly.

No fewer than 16 of these Common Nettle-tap moths Anthophila fabriciana were noted this morning without searching very hard. As previously noted I only saw three all last year. I am probably "getting my eye in" in being able to spot them but clearly they are abundant this year. Many insects do go through boom and bust years. The vernacular name raises the question as to whether there is a Less-common or Uncommon Nettle-tap. As far as I know there isn't!

A Garden Grass-moth Chrysoteuchia culmella on a street lamp pole just after dawn. This group of moths with blue eyes always look surprised. Perhaps they are.

I have been all over the place trying to identify this bee. I have eventually concluded it is probably a Furrow Bee Lasioglossum sp.. I cannot recall noting any previously and by "Field Guide to Bees". There are 34 species in the UK (1700 worldwide that includes the "sweat-bees"). To identify for certain requires the use of the species key at a far greater detail level than can be done from a photo. I will see if the Shropshire bee recorder can help but I expect not.

With a long ovipositor obviously a female ichneumon. Which? The best I can come with is "an ichneumon in the Pimplinae group".

The camera focusses fast but apparently not as fast as my first-ever ruby-tailed wasp, perhaps Chrysis ignita takes off in to the distance leaving an almost equally blurred ichneumon in its wake.

A White-tipped Sawfly Tenthredo livida.

Another sawfly: this is Tenthredo mesomela.

A new hoverfly for me and a strange one at this. It is a Small Spot-eye Eristalinus sepulchralis known to Obsidentify as Black Lagoon Fly (the creature from the black lagoon!).

Another view. Weird eyes! Why?

A Twin-spot Boxer hoverfly Platycheirus rosarum

This hoverfly had me puzzled. After research on Steven Falk's Flickr pages I concluded is the infrequently seen female form of the Common Twist-tail Sphaerophoria scripta. The abdomen of the female is significantly shorter than that of the male which is why the name "Long Hoverfly" has been dropped as not appropriate.

Hard to see against the background clutter is a female Broad-bodied Chaser dragonfly Libellula depressa.

A strange fly I see every year. It is a Thick-headed Fly Sicus ferrugineus. I like the alternative name of Ferruginous Bee-grabber. This group of flies sit with the tip of their abdomen folded back underneath. Why?

One I have been misidentifying. With the thin, tapering abdomen this is a Small Fleck-winged Snipe Fly Rhagio lineola and not a Black (or Common) Snipefly Chrysopilus cristatus as I have been assuming. Both are present in some number. This one had just flown in to a spider's web.

I think this is the gall fly Urophora cuspidata. There are similar species, the precise shape of the black lines across the wing subtly differ and I hope I have this right.

Not very inspiring to look at is this nymph of a Common Flower Bug Anthocoris nemorum. The bug itself is not much to look at either.

This nymph is of the Mirid bug Deraeocoris flavilinea.

A leaf beetle from the Donacia group is about all I can say. Too many similar species.

A new insect for me. A beetle, specifically a Garden Chafer Phyllopertha horticola

A spider I can identify! A Zebra Spider Salticus scenicus.

The white inflorescence of Meadowsweet [or Mead Wort] Filipendula ulmaria.

(142nd visit of the year)

Bird notes:
- initially seven adult Mute Swans with one departing. I was unable to get close enough to see whether any of these birds was ringed. No cygnet seen
- the duck Gadwall not seen.
- a trio of Tufted Duck again. Did they ever leave?
- the brood of two Coots were from what I believe to be the first to hatch. Despite these being well-grown they were in the nest and being fed by adults.
- two Great Crested Grebes. They did not seem interested it getting together, staying in different parts of the water.

Bird(s) noted flying over here:
- 3 Jackdaws

Not intended as a portrait of a drake Tufted Duck, merely to note that now in the post-breeding phase the white flanks are becoming a sullied grey. I will soon be reporting totals without attempting to sex them all.

I was none too surprised that Obsidentify was unable to help me identify this pug moth. It is well camouflaged against the street lamp pole and the pole is heavily streaked by leaves and branches that brushed against it in the winter gales. Hard to see!

A species of click beetle. There are too many that look like this. [not a dung beetle as I originally wrote]. No idea about its small friend, bottom right.
