I reckoned you're having too easy a time. ;)

As for the 2nd one, I think I took it off a birch tree. Struggling to remember though. I've let it go, so won't see the adult.

Hello Angus,
Your description of the Shieldbug on Birch, could fit the Birch Shieldbug but not the Parent Bug which is also a Birch feeder, but without a picture we're stuck for a definate ID. I'm still working on the little ones.

As for having an easy time, I WISH. I have just spent the last week finishing off a report for the MoD, and have three further reports to write, all larger than that one. I'll be lucky to finish them by the new year.

Aww Harry,
You know we all love you :flowers:

Hello Jen :hi:

Sorry about the 'grump'.

In reality I have a job that most people would cut my throat for. I get to spend nine months of the year out in the countryside doing insect surveys, advising on conservation, etc. I work every day when the weather is fine and get days off when it's raining (I had a lot of days off this year). However, the work has to be done, and if it means working a sixteen hour day, then that's what I have to do.

Fieldwork slows down in October and that's when the paperwork starts, the only break I get then, is giving the occasional lecture to Natural History Societies or Field Clubs.

Strangely that's when the pressure is really on, because everyone who has commissioned work wants their report done first. Grrrr. I hate paper paper work. :storm:

:gn:

I can sympathise with that Harry, I'm in the middle of an Odonata survey report for the Wilts Wildlife Trust added to which it's the first report I've compiled [at least one that I've been paid for] and I'm anxious to make it look like it was 'worth' the money ;)
By the way, on the subject of late nymphs. I just found this afternoon what I assume to be a freshly 'emerged' [if that's the right term] Hawthorn Shieldbug. It was next to it's shed larval skin and was still damp and it's markings were pale looking. It was on, of all places, the inside of the lid on a plastic recycle skip/bin at the Trusts office.
Cheers,

Steve.

Hello Steve,
It'n nice to know someone sympathises. I trust you removed the shieldbug to a safer place. I'd feel rather sorry, if it ended up on the local refuse tip.

I know how you feel about your report being value for money, I try and do the same. One thing to avoid is 'waffle', it's far better to stick to the facts.

I always have a map of the site(s) examined, alongside the site information. I always try and obtain photo's of the pond, lake, stream etc which can be better than a written description, these can be placed in an appendix. Photo's of the species recorded can also add to your report, not everyone who reads it will know all about dragonflies or what they look like.

I always include pond or lake area, altitude, weather conditions on the day(s) each site was visited or examined. Even air temperature, if you have recorded it. A detailed description of the aquatic, emergent and bankside vegetation for each site adds more 'facts' and these are important, it shows you are doing the work on site.

Establish a standard method for reporting on each site and keep everything in the same order for all the other site reports.

A page or two on possible/suggested conservation measures on any site you think may be in need of it, is always helpful to the WLTrusts.

Always have a species summary and a note about the known modern and historical distribution of the Dragonflies seen (check with your local BDFS County recorder).

Don't forget to have a 'references' section and an acknowledgements page at the end.

Try and create a personal 'style' and stick to it in subsequent reports, changing styles can be confusing to the readers. People like continuity, so don't make waves. lol.

Always Email a copy to a friend to check it for errors, the human brain is a funny thing, reading over a report you have written yourself and trying to spot errors is difficult, as you tend to read what you think you wrote, and that may differ somewhat from what you actually wrote. (if that makes sense). It pays to print out a rough working copy on 'El Cheapo' paper and go over it with a highlighter pen, it is easier to spot errors in print form, than on a computer screen.

Good gramma and spellin is helpful. lol. Italicise all Latin names. Vary font sizes in a standard way and don't be afraid to use Bold text.

I hope this is helpful, if not, bin it. ;)

Hello Jen, :hi:

If I was clever, I wouldn't have started two consecutive sentences with the words "I always". See post #225 para.3. A classic case of bad English. It just goes to show that even a small 'post' also needs 'Proof reading'. :scribe: :-C

Well Harry, here's another that I now think may be a Shieldbug nymph. It was swept from grass in July. Really very small, only about 3-4mm in length.

Hello Angus,
I've managed to run down the identity of your baby Shieldbugs.

They are second instar nymphs of the Green Shieldbug P.prasina.

First instar nymphs are a pinkish/beige with black abdominal and thorassic markings as per your picture.

In the third instar the black triangular thorassic marking turn to a dark green but it does retain the black cross bands on the abdomen, which is a lighter green than the thorassic area.

In the forth instar the nymph is a uniform green.

In the final instar it reverts to a similar colour to the third instar nymphs but with the wing buds starting to extend from the thorax over part of the abdomen.

I did get confirmation of the ID by Emailing your thumbnails to Dr. B.Nau, the National Hemiptera/Heteroptera Recorder.

Hi Harry,
I brought the shieldbug home with me, waited for it to 'colour up' to confirm it's ID before releasing it in vegetation in my garden. So hopefully it will find somewhere cosy to ride out the winter.
Thanks for all the suggestions and advice on report making. I fear my first one won't be as detailed as you think it ought to be. But then, the reserves manager I'm writing it for is pretty laid back and knows it's my first.
I did take pics of the ponds I've surveyed, but I'm very weak on plant ID [both terrestrial and aquatic]. Consulting wth the county recorder will be easy - that's me ;)
To be honest I think he 'commissioned' me to carry out the survey as a means to utilise the 'spare' fund money. As you know, if funds aren't used then it's harder to justify applying for them, or similar, again!
Cheers,

Steve.

Hi Jamie,
it looks like a Hawthorn Shieldbug to me. The markings look a bit 'muddled' but I guess that's due to a general darkening of the pigmentation that affects most species that overwinter [not sure if they all do - recently got the Surrey book but not had a chance to read it yet].
Not seen any species myself for a couple of weeks so good to know they are still active somewhere.
Cheers,

Steve.

Hi,

thanks. I also though it looked like hawthorn but the previous ones were all about 14mm in length but this was tiny (9mm). Perhaps it is just a runt

Regards,
Jamie

Hmm - yes, the size didn't register when I scanned yur message. It is a bit small isn't it. Perhaps it is a recently emerged specimen and as a nymph had a hard time finding enough food. I wonder if that is normal for late season individuals! Harry - help :h?:
Cheers,

Steve.

Hello Jamie,
It's not a Hawthorn Shieldbug as Steve seems to think, but a Green Birch Shieldbug Elasmostethus interstinctus.
I have lightened your picture somewhat so it is more clearly seen. They do darken down somewhat prior to hibernating. It's usual size is between 9 and 10mm. The shape of the 'shoulders' clearly shows it isn't the Hawthorn Shieldbug.

That'll teach me to go jumping in with both feet. It's more obvious now you've lightened up the pic Harry. Also [and I don't know if this is diagnostic] the tips of the wings are rounded whereas in Hawthorn they look more pointed. Why can't they all stay the same colour - they ought to rename them chameleon bug ;)
Cheers, and sorry for the misdirection Jamie,

Steve.

Hello Steve,
He who never makes mistakes, never makes anything. I have made some really big ones myself, like getting divorced six months before my ex wife inherited 3/4 of a million. Ouch.

Re: changing colour, have you never sunbathed? lol. I change colour dramatically once a year............... When I have my annual bath. Boom, Boom.
