Rhithrogena germanica - Marchbrown - Martovka

Fantastična slika Mixe....oće li taj nastavak

The post about Rhithrogena Germanica is not translating very well.

Are the posts saying the photographs show the nymph of R.germanica?

I am 100% sure the attached photograph shows the nymph of R.germanica - in most years we have it in large numbers on my home river .
Prevod:ne mogu da prevedem lijepo post o Rhithrogena Germanica.
Dali poruke iznad kažu da fotografije prikazuju nimfu R. germanica?
100% sam siguran da moja priložena fotografija prikazuje nimfu R.germanice-u većini godina mi ih imamo veliki broj na mojoj domaćoj rijeci.


In the UK and on my home river there are two species of Rithrogena - R.germanica and R.semicolorata.

The single dark mark that is shown on each femur in my photograph is one of the key factors for the ID of Rhithrogena. This mark is also presant in the dun (sub-imago) and spinner (imago).
Prevod:U UK i u mojoj rijeci postoje dvije vrste Ritrogenije-germanica i semicolorata.
Jedan(jedinstveni) tamni znak na svakom femuru(gornji dio noge,što se jasno vidi na slici) na mojim fotkama je jedan od klučnih faktora za identifikaciju Ritrogena.
Znak se takođe nalazi na imagu ili subimagu.

Aha momci Čika Rej je u igri
Čini mi se da se ne slaže sa vašim fotkama nešto baš


Translation:uncle Ray is on this,beware
I think that he dont approve your photos

Dont happy be vory
I am just joking.....dont vory mate,You are our very good friend and forum is all about debate.

Meni se čini da uvažena gospoda Ado i Ray nisu postavili slike samo vrste Rhithrogena germanica.
Na Adovoj drugoj slici je jednodnevka iz veoma sličnog i rasprostranjenijeg roda Ecdyonurus, čije prestavnike većina balkanskih mušičara naziva martovkama. To nije čudno, jer su ti insekti izgledom veoma slični i imitiraju se istim muvama. Postoji jedan drugi, veoma važan razlog da ih ipak razlikujemo, ali o tome ćemo tek da pišemo...
Ray je pogrešio. Na njegovoj slici je nimfa najrasprostranjenije vrste roda Rhithrogena - semicolorata - Olive Upright. Vrlo ju je lako razlikovati od R. germanica - martovka izgleda kao džin pored nje.

For Ray:Mr.Ray, you are bit wrong .Your fly is Rhitrogenia - semicolorata - Olive Upright. It is easy to distinguish germanica and semicolorata.Germanica is like the giant next to semicolorata.

Hi Mr. Mixmaster
The automatic translator is not working very well on this post, so I apologies if my understanding of what you have written is not correct.

First I think we both are saying that the photo by Aldo is an Ecdyonurus of species, pointing the rear projections are very clear on the pronotum (last segment on thorax) - these are present in Ecdyonurus and not in Rhithrogena.
Second I think we both agree that my photo is of a Rithrogena species.
Third I think we are agreeing that Rithrogena Germanica nymphs are larger (longer) than Rhithrogena semicolorata.
So at least we agree on somethings. : lol:
Both R.germanica and R.semicolorata are found in my home river (they are the only 2 species of Rhithrogena present in the UK)
The scientific key I use to identify the nymphs states that it is not possible to visually separate the two species - R.germanica and R.semicolorata appear anatomically identical.My experience is that at any time in the year, R.germanica nymphs are much bigger and darker in color than those of R.semicolorata.
In the UK typical size of the adult R.germanica is 12 to 16 mm and river on my 13 - 15mm and main hatch is between end of March and end of April (and occasionally May).In both the UK and my river typical size of the adult R.semicolorata is 10 - 12 mm. and main hatch is between mid May and end of June.
My photograph of theR.germanica nymph was taken on 17 March 2009, it already was 13 mm long and very mature, almost ready to hatch, and already
bigger (longer) than the maximum size of R.semicolorata. On the same day I also collected a nymph of R.semicolorata (photo below) and you can see that it
is only 6 mm long and not very mature.

This is the basis of my conclusion that the first photo is of R.germanica and my second is R.semicolorata - I hope it convinces you also.

Hi Mixmaster
There is no need to be sorry - between us we have now got it right.

I have a lot to learn from you.

Prevod:pozdrav Mix
nema potrebe da ti bude žao-između nas smo usaglasili kako treba.
Mnogo sam naučio od tebe.
