Rhinophoridae

The first time I found a Louse Fly, around a year ago, I remember thinking it was a Tachinid and then having no luck I think I finally stumbled across the Rhinophoridae key that is an appendix to Steven Falk's draft key to Calliphoridae.

Yesterday I managed to complete my set of Fife Rhinophoridae with Melanophora roralis. This was my third species this year. Considering the county list at the start of the year was 2 species that's not bad going!

This is the blackest of black flies. Its wings are black. Even its calypters are black. And its halteres. Remarkable. At first when I swept and potted it I expected to just confirm it was Melanomya nana, which is a pretty common fly here (Little Black Blowfly or something like that), so when I popped it out under the microscope last night I was well pleased!

Actually I lied a bit earlier. Since this species was only known from the Isle of May it means there was only one mainland rhinophorid species at the start of the year. NBN shows only 10 records for the family in Scotland, which probably shows a remarkable dearth of dipterist activity as much as anything else.

I also see that NBN has zero records for Rhinophora lepida for Scotland, which maybe I ought to have checked out earlier (did i and I forgot? Maybe). In fact it has apparently a very southerly distribution, though I have two vouchers of it from the square this year!

Anyway, here's the black fly, my only ID success of last night but I can live with that!

Emmesomyia grisea - new to Scotland (probably)

So I finally took a spade to the beach last night to dig up some lugworms. New species are proving a slog at the moment. Birds aren't playing ball though the flies and fungi are sort of ticking along. Two easy ones yesterday though (in ID terms - digging sand is still work!). However the third from yesterday was more interesting.

I decided the other night to give the proper respect to an anthomyiid that I netted at the weekend. Very happy I did too as it's the most northerly record for the species and more than likely new to Scotland - Emmesomyia grisea. As I've been making progress with calypterates it's been bugging me that I've sort of ignored the Anthomyiidae as difficult. Don't get me wrong - they ARE difficult, but they are getting easier. The difficulty lies in their similarity and the consequent nuances of setae organisation (and naming!) that you have to understand to work the keys. Females are still off the list, for the moment at least.

Fly by night

After Friday's new Fife fly while searching for moss I found another new Fife fly while searching for moths. This is a cracking little thing and my first in the Keroplatidae. It's only Fife's 2nd recorded one as far s I can see though there must be lots more. Fortunately it did me the honour of attending my MV trap and even more fortunately (for a change) wasn't in the Mycetophilinae so I actually had a key for it!

I bagged some water cress also on Friday and was pleased to confirm the species which I had suspected was really the more common (in the county at least) hybrid.

Sunday turned up some nice mushrooms and all-in-all not a bad weekend, though a September finish seems to be drifting away

Two steps forward ...

... one step back.

The two steps forward are a nice new county-first soldierfly Sargus bipunctatus and the more routine Spruce Carpet moth. Yesterday lunchtime, having added one moss species to the list, I decided to target another. Not long ago I discovered that a small stream ran through someone's garden and exited at the coast. This wasn't apparent until the house owner cleared the garden of all the overgrown vegetation and exposed a couple of small "pools" (Belfast sinks embedded in the ground!) . So I went to the bottom of it, outside his garden, to see if there were mosses on a couple of exposed rocks. Short answer is yes, but my first guess at ID (a Hygroamblystegium) looks wrong so we'll come back to that.

I did, though, consider that this different piece of habitat might make it worth carrying a net - good call! Settled on a leaf beside a small seepage-type area was the female Sargus.

A somewhat subdued moth-trapping session last night produced only Spruce Carpet. So far. I may have another once I figure out what it is!

On the "step back" the discovery of Lepista flaccida has rolled out to engulf the previously claimed Clitocybe gibba. Examples of the latter proved to be the former under close examination! This means some record revision must be done, probably including for last year. Dammit.

As I approach 1000 I want to be as critical as i can in reviewing the records so that the total is as solid as it can be. Chances of error are still > 0 of course, but that's just a fact of life.

Funnel fun

Got up early this morning to watch some birds fly past but they weren't co-operatiing. They're probably still sulking since they threw me a Ross's Goose last week and I hadn't bothered to go and look. It flew over a nearby watchpoint and probably right through the middle of my square. Anyway ... a Kingfisher settled on the rocks in front of me before hovering over the tideline and making a dive. First time I've seen a Kingfisher hover (well, a British one) so that was my highlight.

A couple of additions from yesterday, but one of them may lead to the loss of another as I may have been misidentifying all the Lepista flaccidas (Tawny Funnel) on my patch as Clitocybe gibba. Doh! I feel like I had nailed the ID but now I need to go back and check. The Eurhynchium I was amazed to find that I hadn't recorded already.

On the ivy front things are looking up, so I expect to spend a lot of time there in the coming weeks.

Yippee!

Game's a bogey!

For those outside the correct geographic area the above phrase means more or less "match abandoned". I now need over 4 species per day to complete in September. Now if there were two days left I might feel optimistic about that with a final push but 4 spp./day over 17 days is optimistic I reckon. I do have some fungi-bothering friends coming nearer the end of the month and I may do a couple of extra shifts on the moth trap but in reality even the stocks are becoming bare.

On the brighter side two new flies last night, so forward momentum isn't completely stalled.

Opomyza florum

Neuroctena anilis

(edit: due to a hardcoded spreadsheet cell the spp./day wasn't updated and is in fact only 3.5! I am actually 9 spp. behind minus whatever i can scrape out today)

The Great Slowing

After a hell-for-leather rush over the 900 barrier it seems that the next slow cycle is here. Material is on pins and in pots but the wheels of identification grind exceeding slow. Fungi especially I can spend a lot of time on without a satisfactory answer.

Last night I managed to key out both of the things I attempted, only to discover that I already had recorded one of them. Well, it was an anthomyiid and I felt pretty pleased about it anyway, especially since of 47 couplets in the genus key it keyed out on the 47th!

The nice shiny new list addition is the solitary wasp Mellinus arvensis. This is the 4th one I've keyed out in my new solitary wasp book and takes me to 33 for hymenptera - about 23 more than I expected I think.

Birds are just .. let's not talk about birds ... have a wasp

Mellinus arvensis
Also since I have a photo here's Hygrocybe acutoconica, which used to be called H.persistens. The latter (former) name was much better because this is one tough Hygrocybe - with a gracile stipe and not discouloring it will hang around for weeks.


Actually on birds maybe it's worth noting the first returning Turnstones and first passage Linnets (lunchtime). They aren't new but why not make a note of it. It can't be all about the new stuff, can it?
