An Exciting Couple of Weeks

The good weather broke through in the middle of July and I have been taking full advantage by getting out as much as possible.  I'll start at the beginning...

On the 15th Malcolm and I did a fishing trip to Milkhope Pond, determined to put some fish on the bank after our previous blank at Brenkley.  The tactic was to scale down the tackle but using baits that would be big enough to put off the tiddlers.  In the end we had four skimmers and two roach, all from the margins on legered sweetcorn and no tiddlers - but no carp either.

The day after we linked up again for a dog walk through the meadows by the River Aln.  Early sightings of a small skipper and a burnet moth promised much but otherwise ringlet and meadow brown predominated.

Small Skipper

On the Saturday I took part in a bee hunt at Watergate Park organised by the Natural History Society's expert thanks to whom we were able to identify amongst others a vestal/gypsy cuckoo bumble bee (which I fortuitously came across), furrow bee (minute) and male buff-tailed bumblebee.

On the side I also noted a marmalade hoverfly and a shaded broad bar moth as well as several more small skippers, which seem to be very common this year and were to appear at further venues.

This Monday I was out hunting hairstreaks and for about the fourth time visited Bywell Bridge only to find overcast weather and little sign of activity in the elms.  By contrast an evening visit to the viaducts at Hamsterley Mill provided two or three strong but fleeting purple hairstreak suspects.  Probably too early though for them to be on the wing in large numbers.

After taking part in a walking cricket session (yes it's come to that!) I went to Wingate Quarry around Tuesday lunchtime hoping to see a marbled white at the only site in Northern England where they are present.  I must have seen approaching 100!  Introduced in the hope that they would spread, they seem to be very happy where they are.  

Marbled White

Also sighted in this very scenic setting were good numbers of small heath, small skipper, common blue (though only 2-3 females) and burnet moth as well as the inevitable ringlet and meadow brown, large numbers of red-tailed bumblebee and I think a white-tailed bumblebee.

Perhaps more significant was this latticed heath moth, which I believe is somewhat scarce.  However, I see that I also have a less good photo of one at Watergate Park too.

Latticed Heath

The day after I set off late in the evening to go on a nightjar watch near Slaley.  Nightjars are rare in Northumberland but we managed half a dozen fleeting sightings as the darkness encroached and heard a fair bit of churring.  The most impressive bit was watching one hunting and returning to the same dead tree. There were plenty of toads and midges around plus an orange underwing moth but only one bat.

Thursday was nominally a day off but I couldn't resist this heron fishing on the edge of the marina at North Shields.

On Friday I was back on the hairstreak trail again, this time with almost completely opposite results.  After some delay I arrived at Bywell Bridge going on on 1.00 pm, having spotted my first red admiral for several weeks on the way.

This time the sun was out and after a few minutes I started to notice suspicious activity in the elm tree at the north-eastern corner of the bridge.  It wasn't too long before I got a positive identification of my first ever white-letter hairstreak.  In the course of the next hour I must have seen 20-30 individuals, coming in little flurries and briefly settling on the tree leaves.  Rather contradicting the advice I had read on the West Sussex Butterfly Conservation site, they were mainly on the sunny side of the tree and not totally out of the wind, which I have however noticed is pretty variable in this location.

By contrast my evening visit to Hamsterley came to an abrupt end after sighting just one suspected purple hairstreak when the cloud moved in and obscured the setting sun.

The weather is closing in again so I may not have so much to report over the next few days!

Bishop Middleham Quarry

After a year long covid-inspired delay, a few of us from the Naturewatch group finally managed a trip to Bishop Middleham Quarry, which is one of the highlights of the Durham magnesium limestone belt.

It was indeed a productive habitat and very easy on the eye.  The flora are probably the most outstanding, notably the helleborines and orchids, of which we saw I think four varieties.  The ones not pictured were common spotted and fragrant orchid.

Of course a large part of my interest was the hope of seeing some less common butterflies but the conditions were rather overcast and our hopes were not high.  Fortunately we got the best of it around midday wheen a number of ringlets started to show and it wasn't too long before I saw the star of the show - my first ever brown argus in this country and it proved to be the first of several.

Distinctly small in size, I was also surprised by the amount of blue on the body.  I also found myself wondering about nomenclature as the Northern Brown Argus is supposed to occur here too. However my European Butterfly Guide talks instead of Mountain Argus but they appear to be the same thing.  As the Northern version of the northern/mountain species has a white not black upperwing spot, I'm confident it wasn't what we were seeing. Never mind the fact there are examples with black spot within a white spot!

Away from the wonderful world of terminology, further butterfly species sighted were meadow brown and small heath.  Thre was just one common blue and no appearance by (perhaps surprisingly) small copper and less surprisingly wall brown (not sunny enough) and dingy skipper.

Ringlet

Only two burnet moths were spotted plus one other I needed to research to discover it was a blackneck but there were surprisingly few bees.  The ones that were out were mainly carder bees and red-tailed bumblebees.

Red-tailed Bumblebee

It's funny how you see things again not long after you've seen them.  While helping out at the tennis club yesterday there were a couple more of the common wave moth I spotted in Cumbria.  And this morning while out for a paper there was another small bumblebee on lilac that had a red tail.  The trouble is it also had a second yellow stripe on the abdomen and I had neither camera nor mobile phone on me.  So I'll have to pass on that one.

New Species Seen

Last Saturday I took a chance on the weather improving for a trip to Campfield Marsh in Cumbria with my son and fiancee in the hope of seeing a marsh fritillary.

Unfortunately the sun refused to shine but it was still a pleasant walk in a wetland environment with some different flora and fauna.

For a while I thought the only sign of butterfly or moth would be a drinker moth caterpillar but on coming to a woodland edge I noticed a moth that I later saw a few times - an aptly named common wave.

Further into the wood I saw a couple of light-coloured bumblebees I didn't recognise visiting foxgloves.  It was frustrating trying to identify them but I think from video evidence they were moss carder bees.

There were also a few birds around, notably a little egret, a single speckled wood butterfly and a strange growth on a tree.

Still after marsh fritillaries we dropped in for a shorter walk at Finglandrigg Wood with no more success but I did see the first definite meadow brown of the summer on one of many common spotted orchids and another bee imitator, this time a bumblebee hoverfly... if I've got it right.

Back at home the day after I spotted to spot a patchwok leafcutter bee, no great rarity but a first for me.

The jay is still  appearing from time to time but is very shy and disappears as soon as I move around in the house.

As you can see, s/he's about to disappear again.

I thought that the baby woodpecker was now feeding independently but there was a recent visit yesterday when the parent bird obliged, I think with some reluctance.

Woodpeckers

This Tuesday another butterfly target went unachieved as, in spite of reasonable weather, I couldn't see any sign of the white letter hairstreak at Bywell Bridge but there were a couple more first seasonal spottings when I saw a small skipper by the Tyne as well as three ringlets.  The latter may have been fresh on the wing and weren't settling but I have seen a couple since.
