Hi Nick,

Interesting to hear details of your portable trapping efforts. I find that some trapping sites, even if they look good, are often poor for reasons that often baffle me.

I read a study once that reported micro moth diversity to be greater inside woodland than at the woodland edge – my own personal experience is in line with this. With macros, I tend to find that things are the other way around, but the make-up of woodland interior catches is usually noticeable different from the make-up of woodland edge catches.

I look forward to reading of your further mobile trapping exploits.

Iain,
This whole business of two different light sources and their respective catches is, at the moment, causing me some angst. Superficially it seems that the two attraction mediums ought to be regarded as stand alone although obviously there will be a large degree of overlap.
In this regard I'll post more fully at the weekend.

Nick.

Hi Iain and Nick,

regarding catches of moths in promising looking habitats, I did an Open University course years ago which included a study of a site in England which was allowed to progress over a long time from an open field to woodland. It was discovered that as the site advanced towards "climax" vegetation (in this case woodland) diversity (of total species) actually decreased. I remember thinking that this suggested that the type of pristine habitats which were favoured for conservation purposes were maybe not the best places to be offered protection. Maybe better to value derelict urban sites, non descript looking woods, and generally places which are edgy, neither one thing or the other and subject to random change. I am not condoning draining raised bogs and chopping down ancient woodlands - these places may contain distinct specialists - but rather finding a way to evaluate all those horrible places which should be dreary and dull, but actually turn out to posses fantastic diversity without anybody with a "management plan" being anywhere near them. Iain, it would be interesting to compare the moth diversity (for example) at the woodlands of Ardeer Quarry LNR with that of a fine ancient woodland. What is important? specialists versus diversity. The same OU course (I think) proposed that diversity influenced resilience, and that if humanity was to survive we should pursue diversity.

Alistair.

All,
After last weeks capers I've restricted my self to trapping at home with nothing of much interest to report, Merveille du Jour is always nice to see, a regular but not common species here, as is Brown Spot Pinion. Sitting outside with my mid morning coffee on the 24th a very large moth flew across the bottom of the garden so close that I could see the wing beats, I presume it to have been Convolvulus Hawk Moth which I have recorded here once before in Sept 2003. Annoyingly it has yet to show up in one of the traps!
On the subject of traps plural I've been running the Actinic about 5 metres from the MV and by and large the catch in the Actinic is better than in the MV. As you will see below I didn't run the Actinic on the 25th but when I looked prior to bed there were a lot of moths around the MV, certainly far more than were reflected by the catch. Conversley, in the past, when I've run the Actinic and left the MV switched off the number of individuals seems to drop....I'm sure that we can all see where this is going!

Iain,
This Ichneumon caught my eye in the trap on Sunday morning. It was so distinctive that I thought it would be an easy ID, how wrong I was!
As you previously alluded to an interest in wasps...over to you. The white on the rear legs forms an unbroken band however the white on the antennae is dorsal only, as is, (as far as I can see) the white on the middle legs. Sorry, don't know the correct term for them. As you can see I retained the specimen, should you want it for detailed examination let me know.

Hi Nick,

Thanks for the offer - I’ll contact you off-forum shortly re. getting my hands on your insect specimen. Whereas there are a couple of hundred species of solitary wasp in the UK, there are thousands of ichneumon species. I can’t tell at the moment whether or not it belongs to a family for which there are identification keys available.

All,
Another worthwhile week in terms of catches, once again the actinic proving its worth. I'd started to wonder about the MV bulb's effectivness (apparently ions migrate from the fillament to the coating on the inside of the bulb and act as a UV filter)
At a rough count I reckon the bulb must have 5 or 6 thousand hours under its belt so I replaced it with a new one for the night of the 4th but it didn't seem to make much difference!
Haworth's Minor was a nice surprise for the last night of September, a species I hadn't encountered before. Second generation Brussles Lace last night (4th Oct') was also interesting.

Sorry about the lack of photos but it's just not 'dooable' at 6.30am.

Hi Nick,

Those are some very good catches for this time of year. I read a suggestion somewhere that actinics do better late and early in the year.

All,
I'm only trapping on Friday and Saturday nights now unless the weather looks to be unusually still, mild and dry. This year seems to have finally 'hit the wall' with a marked drop in both numbers and species last week.
With the exceptions of Angle Shades, Pine Carpet and Green Brindled Crescent all of the following list came from on or around, but not in, the traps. The Epirrita which chose to settle on a red watering can amused me, clearly its self preservation genes were lacking!

All,
Despite my rather gloomy prediction last Sunday this week hasn't been too bad at all.
Small Fan-Footed Wave on the 15th gave me some trouble due to the time of year, R.Leverton kindly confirmed it and opinioned that he had not heard of a second generation in GB before.
The Brick on the 17th was a new species for here, and The Streak on the same date is at best occasional.
The night of the 18th was so windy that, although in a sheltered corner, the Heath Trap was blown over
