Long-tailed Blue

 


A couple of years ago we planted Everlasting Pea in the garden in the hope of attracting the Long-tailed Blue Butterflies. Mid September, last year, and we had success with a couple found in the kitchen and another three in the garden (see blog here)

There had been no sign of  caterpillar action on the Everlasting Pea but perhaps just having the plant in the garden is enough to attract females looking to lay eggs late in the season. The males will be sure to follow. We also have late flowering nectaring plants in the garden including Verbena which the butterflies seem to like.

This year September was no show and by the end of October I was starting to give up hope, my latest sighting ever had been 25th October. Then on 30th October during a heavy rain shower Sue walked into the kitchen and spotted one sitting on the kitchen window.

The next couple of hours played out exactly as last year. I took a few photographs. The butterfly refused to stay on any of the household green plants, preferring the windows and work surfaces. As with last year it only gave me one brief view of an open wing shot. Not ideal but you have to take whatever you are offered and it at least shows that this is a female.

With heavy rain outside I left it on one of the windows where it sat quiet happily till late afternoon.

Then with the sun breaking through I through I might have a chance of a picture on the garden greenery. I took it outside on my finger and gently placed it on the Verbena, with the image of it nectaring on the blue flowers already in my mind.

It was not to be, the instant it touched the plant it took off high over the garden, hovered there for about thirty seconds, then took off across the adjoining gardens. A replay of exactly what happened last year.


Long-tailed blues have successfully bred in this country but it is not clear if they can survive the winter in any stage of their life cycle. Perhaps with climate change we will eventually have a self supporting colony here.

I just hope she survives the incoming Storm CiarĂ¡n.





Willow Tit

 


Willow Tit, a rare bird for me as we don't get them in Sussex. I was staying up in Derbyshire with the family for a few days and with a rainy wet morning, the others were either off swimming or having a lie in, so I headed over to Carsington Water to see what birds were about. The target was the Willow Tit which e-bird said had been reported from around Stones Island on the reservoir.

After a couple of hours wandering around in the rain I had seen plenty of birds but had little in the way of pictures to show for the effort. A distant Tree Sparrow eventually gave itself up for a picture but on checking it later my initial reaction was to delete it. Mist, dull light and high ISO had given an image that was barely recognisable. Second thoughts when I got home and half an hour playing around with Photoshop eventually gave me a recognisable, if disappointing image.


Tree Sparrow

Still it was worth recording, my last sighting was at Bolderwall Farm Dungeness in 2019.

No sign of the Willow Tits so I retired to the bird hide adjacent to Horseshoe Island to eat my breakfast. It had a couple of feeders with various tits and finches dropping in to feed. I don't like taking pictures of birds on feeders but with a chance of the Willow Tit it was worth getting the camera ready.

Nothing unusual for thirty minutes or so but as I was getting ready to leave a bird dropped in that looked promising. I managed to snap a few quick pictures and it was gone. 

The trouble with photographing birds is that you don't really look at the bird, you are so focussed on taking the picture that you don't see the detail. Once it had flown I realised that I didn't know if it was a Willow Tit or a Marsh Tit.

Fortunately a couple of the pictures gave a clear view of the bill with no white spot on the upper mandible and with a face pattern and a pale wing patch that strongly suggested the Willow Tit. I didn't hear it call but I did have the Merlin App recording and it was showing Willow Tit confirming the sighting.

So a miserable wet morning had turned into a successful birding session, my first Tree Sparrow for four years and then my first Willow Tit since 2016 at Fairburn Ings.

I also had good views of Dippers on the River Dovey but unfortunately was travelling light that day and had left my camera at home. Three birds I do not get to see in Sussex, I will have to visit the area again.

Spectacles

 


The weather in July had not been good for putting the moth trap out but with warm dry weather returning at the end of August and into September there was a chance to do some catching up. The moths would be different but there might be an opportunity  to get some new garden ticks.

Plenty of moths but where to start, perhaps the Spectacle. Easy to spot from the head shot but a bit harder to tell the Spectacle and Dark Spectacle apart.


Spectacle


Spectacle - Abrostola tripartita


Dark Spectacle - Abrostola triplasia

They are probably easy to tell apart when in pristine condition but once a bit worn and with markings beginning to fade it becomes a bit more challenging.


There have also been good numbers of less common moths, ones that I would have considered rarities and probable migrants, just a few years ago. Portland Ribbon Wave (6+), Channel Island Pug (6+), Blair's Mocha (10+), Clancy's Rustic (8+), Given the numbers involved and the nights they were caught I think local breeding populations are more likely.


Portland Ribbon Wave - Idaea degeneraria



Channel Islands Pug - Eupithecia ultimaria


Blair's Mocha - Cyclophora puppillaria


Clancy's Rustic - Caradrina kadenii


Clancy's Rustic - Caradrina kadenii


Best moth of the year so far and new for me, a Convolvulus Hawk-moth. It's not the rarest moth that I have caught but there is just something that raises the spirits when you open the trap and see a hawk-moth sitting there.


Convolvulus Hawk-moth - Agrius convolvuli 


Also new a Dewick's Plusia and an Old Lady.


Dewick's Plusia - Macdunnoughia confusa


Old Lady - Mormo maura


Others worth recording


Radford's Flame Shoulder - Ochropleura leucogaster


Scarce Border Straw - Helicoverpa armigera


Hedge Rustic - Tholera cespitis


Blackneck - Lygephila pastinum



Four-spotted Footman - Lithosia quadra


A lovely Frosted Orange, new for me but unfortunately not found in the garden.



Frosted Orange - Gortyna flavago



Large Thorn - Ennomos autumnaria



Straw Underwing - Thalpophila matura


Also a couple of green coloured moths. The moths are not rare but I don't find many of them in the trap.


Light Emerald - Campaea margaritaria



Small Emerald - Hemistola chrysoprasaria


One new micro


Red-barred Tortrix - Ditula angustiorana


And two that got away from me. Nice pictures but they need dissection to confirm the identity of the moths. Must check to see if there is anyone in West Sussex that offers this as a service although I am not really sure that I want to kill them just for the sake of my garden list.


Bordered Marble - Endothenia marginana or Teasel Marble - Endothenia gentianaeana


My money is on the Teasel Marble but I will never know. Over a hundred of these two species in the county records, were they all dissected to identify them?

And below what I thought was a Clover Case-bearer but now relegated to Coleophora agg



Possible Clover Case-bearer - Coleophora alcyonipennella


The catch through August and September has been good although I am still below last year on the number of different species recorded, with the bulk of the numbers usually made up of Box Tree, Yellow Underwings, Lunar Underwings, Rusty-Dot Pearls and Light Brown Apple Moths.


The moth trap is out again tonight, maybe still a chance to catch that Oleander before the cold weather arrives!
