A lot less bovver

Lunchtime I headed for the coast to try my newest piece of surveying equipment (will be revealed if/when it works!) and found my tenth hover species of the campaign. Not bad up here for April, and intriguingly the 9 species I've recorded on my inland reserve by this time of year are quite different from those I've found here on the coast.As far as I know only the Eristalinus is truly coastal though Platycheirus ambiguus seems to have an affinitiy for Blackthorn which the reserve doesn't have. The rest may be made up for in the larger woodland where the reserve has species of grassland and waterside. I have yet to see a Cheilosia or an Eristalis!

I was surprised to spot a large bumble bee on seaweed half way across the rocks, and fortunate enough to net it and see how good a mimic the hoverfly Criorhina floccosa is! This is another new species for me and this shift of habitat (I do usually hammer the same patch(es) over and over anyway) and I'm looking forward to seeing what other surprises are lurking. Actually I have found also a Dasysyrphus larva but not ID'd to species. I'm feeling pretty comfortable with a prediction of 50-60 hovers, though it may actually go beyond that

Better late than never - Phaonia errans

RES key:
 1. no ps acros
11. mouth not in front of frons
13. palpi not dilated
14. 4 ps dc
15. scut apex trans r-y
19. no bristles front tib
21. eyes hairy
23. all femora r-y
Phaonia errans

I have tried this on several species of Phaonia before finally finding the right foot for the slipper.  I knew it didn't match anything I have n my box! Good news is that it's a new addition to my box.





500 not out!

So this morning Nebria brevicollis became my 500th species for the square. I tried very hard last night to make it a muscid fly but it was refusing to lie down!

Nebria brevicollis
I must have a bit of a review later but it's great to be at the half way stage and 4 days before schedule. Also during the course of yesterday evening the site coughed up my 100th lifer of the year in Psylloides napi.

Also I really should mention how good Duff was in sorting out a flea beetle I never thought would happen, although to be fair the FSC guide was if anything more direct.

And so without further ado, here are the final entries of the end of the beginning
497 Gongylidium rufipes A Linyphiid spider
498 Tipula varipennis A cranefly
499 Psylloides napi A flea beetle
500 Nebria brevicollis A ground beetle

My new water trap

Courtesy of the soul-of-the-world, the tides and some careless tupperware husbandry I have acquired a new water trap.Found it the other day when I had a bottle of soapy water with me (doesn't everyone?) and thought it might be worth a spin. Apparently it was.


48 hours after siting it had the aforementioned two calyptrate flies, three Linyphiids, a millipede and two beetles (actually also some springtails but looked Orchesella vanilla). I spent the morning wishing I brought my sweep net out as there must be Linyphiid treasure in them thar hills.

Fly and pineapple sandwich

Found some pics of a fly that I caught the other night, photographed, identified and ... forgot! No recording, no adding to the list. Poor thing. Well, now it's on the list with my humble apologies.

My Sandwich Tern finally showed up this morning and some pineappleweed in an untended flower bed was an easy mark. Those places really are good for ruderal species. I'm sure there's more in there, too.

Also I'll later feature a water trap that looks like it's going to do the business.  It's a discarded tupperware dish rescued from the strandline that probably fell off a yacht. Half-filled with sea water and topped with a small amount of detergent. This morning's unidentified catch: two calyptrate flies, one millipede, two beetles and three Linyphiid spiders.Not a bad haul and the top's not even level with the ground.


Numbers:

494 Dicranomyia chorea A cranefly
495 Sterna sandvicensis Sandwich Tern
496 Matricaria discoidea Pineappleweed

Zombie Crab

After adding a handful of not-particulary-interesting microfungi and another couple of flies I was able to make a low tide foray on Sunday morning. First Common Terns of the year were screeching around Hopeward Point and I eventually found this young Edible Crab ...



I don't expect to see Spirobranchus worm on the top of a baby crab so I turned it over and ...


there it was -  Sacculina carcini - the parasitic barnacle, noted to be common in Green Shore Crab population, but apparently also in Edible Crab.

Pushing on towards the 500 seriously now and should break it before the end of the week without too much trouble

Lunchtimus mirabilis

It was 50/50 whether I finally caught up with gym time or went outside at lunchtime. Fortunately I went to bed to late last night to be bothered with the gym and it was sunny into the bargain.

Headed straight for the blackthorns where I had caught and then lost a lovely tachinid yesterday, which I'm pretty certain was Paracraspedothrix montivaga, a species I have recorded in the square last year. Anyway ... First to catch my eye were Peacock butterflies chasing up and down the upper shore, before I spotted an all dark large hoverfly on the strandline. Could it be?

A swing ... and a miss. Fly escapes. Next it, or another of the same, shows up on a blackthorn flower but in a tricky spot. A swing ... and a miss. Aaaaargh!

Suddenly from the strandline a large beetle burst onto the wing and i thought I was in for my first carrion beetle of the year. But no! What the bejeesus is this?! A fantastic Creophilus maxillosus, a big furry Staph of similar magnitude to the Devil's Coach Horse only all fancy-likes with a fur coat. What a beauty! This is a quick record shot and the distribution map for the species as per NBN (I happen to know it HAS been recorded in Fife). In case you don't know where I am, it's just above Edinburgh in that vast white space ;)



After a ten minute stalk I did manage to catch not one but two Eristalins aeneus, first for mainland Fife and a fly I've been longing to see for a long time. For completeness the pic and map for that species too.

The forgotten moth - Phyllonorycter geniculella

So I potted a swept moth from the woodland floor. It lived (loosely speaking. it was terminated) in the pot on my desk for a few days before being taken home and again languished in the "to do" list despite being a lovely little thing that I was genuinely interested in looking at.

It was obviously a Phyllonorycter, and only on further investigation turned out to be geniculella, a leaf miner of sycamore, which is abundant in the woods


Another moth, not forgotten, was this fantastic Beautiful Plume. It's an adult hibernator and it's only been a week since I had one in the garden trap one square away.



Not quite so immediately appealing is this saxicolous lichen by the shore - Opegrapha calcarea

Diptera day effects roll on

So on the 12th a lovely sunny day produced lifer Epistrophe eligans, lifer and county first Platycheirus ambiguus and now another lifer and county first - Lypha dubia (Lifer non dubia in this case). A nice start to spring!

Many thanks to CR for his usual invauable assistance




Good Friday - Mollusc Magic

Had a nice wander around at low tide on Friday with some new mollusc action. First I was amazed when I looked down at a small pool in the sand to see a squirt of water break the surface. On closer inspection I found a scallop which when picked up tried to swim off (in the open air - didn't work). I tried to persuade it to swim after that but it was having none of it.

Next up an overturned rock produced a Grey Sea Slug which was a great addition. But it wasn't over as it seems a peculiar looking collection of eggs in a spiral ribbon appear to be Sea Lemon eggs. I still need to confirm that this is a structure unique to the species but the implication in Collins is that it is.

A few other bits and pieces were picked up over the weekend, not least the new-for-county hoverfly Platycheirus ambiguus, the males of which were loosely swarming over the flowering blackthorn.This is my third addition to the county Platycheirus catalogue.

Spring bounce and numbers

The species per day total is starting to reflect the spring bounce, with March a hiatus between the counting of the winter and "ever present" species and the beginning of the spring emergence of plants and animals. Or maybe that's an overanalysis. Anyway, long may it continue. An average of three species per day really ought to be quite manageable for the next few months.

spec/day rqd 2.29 2.17 2.11 2.08
spec/week rqd 16.01 15.17 14.79 14.59

I finally got aruond to incorporating this year's totals into the ones from the end of last year, showing a total of 573 species for the square.

Diptera delight!

A good lunchtime yesterday when I discovered the blackthorn on the shore was in flower. It was breezy, but a small corner was sheltered by a rock outcrop and so attracted a good range of flies. Some I;d already counted, some I couldn't ID yet and some were new. This included Epistrophe eligans, a spring hover I've been after for a couple of years, and a scathophagid which was to be my 200th fly. I had hoped it would be the tachinid I caught but discretion was the better part of valour there and it's currently pinned with its bits out before I attempt to ID it. (it was county first Lypha dubia and the M.mellinum on closer inspection were county first Platycheirus ambiguus!)

So my 200th fly is the shore scathophagid Ceratinostoma ostiorum

( Scathophagid keys and atlas are available free here )

The Epistrophe is also my 75th hover, which is a nice mini-landmark. I expect that the total number of hovers from this year in the square will not be far off that, the square already having produced some very nice hover records.

200!

Oh look - an Eristalis ...

but wait ... no wing loop! Epistrophe elegans

Double-counted Agonopterix heracliana. Damiiiittttttttttttttt

One down. 451.

Pooh and The Rather Blustery Day

Bit blowy here yesterday and almost a high tide too, so not much was to be made of sweeping or rock pooling/turning. The up side of this is that I had to pay attention to something else and I noticed a good handful of flowering plants that had emerged un-noticed in recent days.

With nothing in sotck for evening perusal I did manage to add a couple of species to the square - but only from last year! At least they were both new for me.

As I approach the 500 I do notice a slight fatigue creeping in, particularly when identifying groups I don't really "care" about (yes, that exists!). I may re-jig the target groups to de-emphasise groups that I find tedious. It has to be fun, hasn't it?

Bee Fly

A nice bee fly was the most enjoyable find of the weekend, and one (same one?) was buzzing around the flowers of Honesty yesterday, busy enough to ignore me taking dodgy mobile phone pictures. Some flies proved to be either repeats or tricky, so my stock of unidentified flies grows. Hopefully I will find time to resolve at least some of them shortly. I do always forget just how steep the on ramp is when invertebrate activity starts up though!



Numbers bit;

Sweeping changes

Sweeping pathsides yesterday turned up quite a few species - flies, sawflies and bugs - though most of the flies are already listed as is the common Anthocorus bug. Bibio johannis was a new one to me, (and the species on the front of the Bibionidae key!) while I was surprised to find that the sawfly Aglaostigma aucupariae was already on my PSL list.

Bibio jonhannis

Aglaostigma aucupariae

Not a bad haul from yesterday then, with five new additions.I also just noticed that I have forgotten to add Arion ater from the other night, so I'll have to do that too.


436 Phylloscopus collybita Chiffchaff
437 Fannia mollissima A lesser house fly
438 Bibio johannis A Bibionid fly
439 Triphleba lugubris A Phorid fly

Painting by numbers




The chase is better than the catch

Last night wandering with headtorch along the coastal path I caught only previously recorded moths and not much else, but at one point I saw the reflection of eyes from the rocks below...

I could see both eyes as perfect circles of reflection and walked slowly towards them, hoping whatever it was would be dazzled or at least a bit confused (spoiler - it wasn't a Snipe). Suddenly I felt the animal tense, a barely percetible movement of the reflections. I prepared myself - if it moved left or right, as it was sure to, I would know what it was ... then there it was! A flash of black and white ... the tinkle of a bell on a collar ... sigh. Always the most probable, but it is my first domestic cat in the square.

Luckily a new spider and a late night email letting me know my Anthomyiidae couple had been identified saved the day

This is Lasiomma seminitidum. Not well known from Scotland but in typical fashion it's already recorded for years on end by my invert-bothering buddy Gordon. It's probably everywhere. Some species just don't get recorded by anyone!

Lasiomma seminitidum

Today, finally, I recorded Chiffchaff. Like Collared Dove I suspected I may have to wander inland to houses and other small woods to score, but it showed up. Still no Sandwich Tern though.

Bumping along

A sunny day with a lowish tide but I couldn't get any traction on rock turning for some reason. Failed to find the great rock I turned yesterday and mostly found only Green shore Crabs. I didn't catch the same Sea Scorpion again as I figure it could use a break.

It was one of those days when you feel the season has changed. Bluebells were out all over though I swear I saw none yesterday! Calliphora were abundant on every sunny stone - vicina and vomitoria. And where last week there was a bee or two they are now buzzing here there and everywhere. I probably should have made more effort to connect with another species but (I'll say it quietly) I just can't get exercised about bees.

Keeps the numbers ticking along anyway. Soon individual pots will be replaced with a WatDon big ol' cannon pooter and my backlog of unidentified flies will start to look vaguely intimidating.

Tedious wildflower

Lovely Hopeward point

Latest numbers:
03/04/2017 426 Asterias rubens Common starfish

Revisions

Eagle-eyed observers may have noticed me reporting two different species as the same one yesterday, mixing my long-spined and short-spined sea scorpions. Yesterdays newbee was the Bull Rout Myoxocephalus scorpius (too many English names - that's what I blame!) and its orange underside appears to indicate that it was a girl.

The putative nudibranches were, of course, not. I had idly wondered if they were sea squirts as I walked back to the car yesterday but I honestly didn't know even what kingdom sea squirts belonged to...

Anyway, they were the sea squirt Ascidiella scabra. The quantity alone should have been enough to avoid going down the nudibranch flight of fancy.  

On putting them under a lens in a petri dish i spooked a scaleworm which was apparently resting on them - the already-recorded Lepidonotus squamatus Or is it. Am I mixing up two scaleworms ...

A fried egg?

Two siphons
