Hover time

My kitchen rocket plant which has attracted so many hoverflies to a sheltered spot just by the front of our house over the last couple of years did not reappear this year. Last year we tried growing some Nicotiana in the vague hope of attracting Convolvulus Hawk-moth (bit of wishful thinking I know), the plants did grow and flowered at the right time but didn't really attract much, let alone the hawk-moth. This year we tried some dwarf sunflowers, some in pots (currently tucked away in the conservatory so the wind doesn't destroy them) and some transplanted into the veg patch (fingers crossed with those). I also came across a random crucifer and put it in a corner of the bean patch. The last couple of days have shown the value of these plantings.

 Two Episyrphus balteatus and a Syrphus sp on the crucifer


 Female Eupeodes corollae on the flowers (id the yellow runs across the margin from upper to lower body surface).
 Female Syrphus, either vitripennis or torvus, to get to species level need to see the extent of the tiny hairs on the 2nd basal cell of the wing, a microscope job.

Out and about down the track and around the Wee Wood there have been huge numbers of hovers. Cheilosia illustrata has just begun to be seen in some numbers. It is a small and not especially good mimic of bumblebees.

Most hovers were on Creeping thistle heads.

I counted 139 Helophilus pendulus between the Weee Wood and the hawthorn hedge, but there were 100s more than that I suspect.

 In amongst all the H.pendulus I did find this pair of Helophilus hybridus. Black line between T2 and T3 absent in male and  hind tibia with apical half (rather than third) black.  I usually find that the stripes on the thoracic dorsum are less bright.

Syritta pipiens and thing (LJ can you get that to family?)

Sericomyia silentis a wasp mimic

 Male Platycheirus manicatus, front tarsi enlaged, dull thoracic dorsum, yellow/orange and black

Female of the same species showing the sticking out face (females do not have enlarged tarsi).

There have been some good moths lately as well, I'll post them shortly.

Windy and quite wet here today, not much good for insects but I got a new bike the other day, well I've had the Kona for 26 years so I don't think I'm being too extravagant and got a good deal via the Cyclescheme (tax free (ish) purchase). So time to get muddy...

Micros

I've been running the actinic down in our Wee Wood these rainy nights. Last nght was the first time for ages I'd run the MV, not a huge catch but a few micros of interest. Micros are a bit of a pain in many respects even if they are in the trap that is no guarantee that they will make it to a usable image or in to a pot. I usually try for both unless they are something like Eucosma cana (seen quite a bit and distinctive), Cnephasia sp (need to be dissected to get to species level), or totally worn (surrender!). Usual scenario - see micro, grab camera, aim at moth, look in screen, press button and review shows it flew off in that moment. Or - get pot, get paintbrush, moth flies and lands on outside of pot, on me, on nearby surface, and then vapourises never to be seen again. Even if I get a decent image then identifying micros is a whole other ball game... Sterling and Parsons is excellent but still a challenge. Fortunately the recorder is very helpful and so are some of the folk on the local Facebook group. I've recently signed up to the UK Yahoo group as well. But micros are worth the effort as some of them are lovely things.

Acleris bergmanniana, a lovely wee thing and quite local

Agonopterix nervosa, new to me but common

Agriphilia tristella, a large "grass moth"

Fairly sure this is Scoparia subfusca


I can't figure this one out, a dark form of Endothenia quadrimaculana maybe. Whatever it is I see it quite often.

On The Shunan the juvenile Moorhen and juvenile Coot are closely associating, following each other around and feeding together. The adult Moorhens are still present but the adult Cotts left ten or so days ago.

Yesterday this Blackwit with a damaged leg was feeding by the track. In order to change its feeding place without flying it would balance on its bill and one good leg and flap to maintain its balance.

Poor, neglected blog

I haven't posted anything for ages, I will try to back-fill from here...


Smart but nasty! I originally identified this as Notch-horned Cleg, Haematopota pluvialis, but it has been pointed out to me that the similar Black-horned Cleg, H.crassicornis has been recorded here, or is at least possible. I need to look at all the photos now and see if I have one from the right angle to see the notch!

I think this photo shows the notch...


Yesterday I saw the first two Udea lutealis of the year, the first one was conveniently in the garden.


Decorating for the last few days, I managed to get a splinter in my finger.


It was straight down under the nail and broke off, ouch! The dissection kit for insects came in handy!

The day before I pulled this out of the MV trap.




Not great pix, I have it in the fridge and will try to get better ones but it is Palloptera quinquemaculata (confirmed ID) which until recently had not been recorded from Orkney.
 
Palace this evening and there were quite a few waders at low tide at the burn mouth, 15 Sanderling, 25 Dunlin, a Turnstone, some Ringed Plover, good numbers of Redshank. Only the second Arctic Skua of the year flushed everything briefly.

Orcas from the garden

Scanning from the garden towards Clestrain Sound, 10km away, and looking for Gannets there were a few big splashes. Gannets I thought and then had a re think as I hadn't seen a bird and those were mighty splashes. Next thing a large black shape hurtles out of the water and makes a more serious kind of splash, ah, so that explains it. Louise had a look as well and the beast breached again. Couldn't see any white markings unfortunately, the distance might have had something to do with that.

The scanning had earlier produced brief views of an Osprey. The pair of Goldfinch from yesterday re-appeared on the front feeder.

No pictures of any of these but some nice hovers and some moths earlier and a backlog of photos to post anyway.

Invasion - what does it mean?

Millions of the tiny migrant moth Diamond-back have arrived in the county, the garden and any sheltered spot is full of them. As the afternoon shifts to evening they begin to fly and yesterday evening it appeared were generally heading north. On Friday night there were 116 in the MV but in perfect catching conditions on Saturday night there were 414. Today there did seem fewer about and last night the MV caught only 15 or so, but I over-slept and it was a clear bright night. There have been other migrant insects also with four Painted Ladies, Silver Ys in the MV and four Dark
 Sword-grass.

 The invading force has arrived



Quite likely a migrant also, Angle Shades

Silver Y a classic migrant

I don't see many of these, Dark Sword-grass

Star moth of the last few days is this Glaucous Shears, a tick

I'm writing at nearly midnight and have just finished watering the garden, at 1:00 this morning there was still a very healthy glow in the sky. The not getting dark is odd, even after being here for seven years it is still odd.

Having dipped on Cuckoo last month when younger daughter got one in the garden I was finally rewarded this morning as I fettled the moth trap, first one in the garden for two years.

There are also hundreds of these about at the moment, Cocksfoot Moth, Loch of Bosquoy


I had come across the CMs here before but this was new for me -



Nettle-tap

Hoverflies have been pretty good too with these my favourites


A slightly confusing Helophilus hybridus, thanks to Roger Morris for confirming this

This one was more typical and an easier ID


Eupeodes corollae

Both these species are potentially migrants also.

Other than the Cuckoo it's all been a bit quiet on the bird front the odd Redpoll has popped in on the feeders or flown over but mostly it's checking on the breeding birds... a flyby Bee-eater wouldn't go amiss.

Sitting on a post means just one thing...

Something's awry
