Tephritidae in Düsseldorf (24.7.19)

Hello Peter,I think that the wing is more like Rhagoletis cingulata. You should seek the opinion of a specialist. You could post at diptera.info and get an opinion from Ben Hamers or Valery Korneyev. Side note: I think that R. indifferens has been removed from the list of German diptera, so genitalia would be needed to prove its presence in Germany. Best wishes, John

Große Echte Fliege (Muscidae) am Licht (05.08.19) --> Mydaea corni (m)

Hello Jürgen, you often find odd flies. this one should be recorded because it is larger than usual. I think that Mydaea are recorded at 10.5mm but this is a bit larger. Very interesting. Best wishes, John

Melanomya nana vs. Phania funesta --> Phania funesta

Hallo Rainer, field recognition is easier if you keep this in mind: the wings of M. nana are infuscated. The abdomen is more slender and lacks strong bristles like that of a Tachinid. see my photo attachment of M. nana female. Notice the infuscated wings and long slender abdomen lacking strong bristles. Best Wishes, John

Schwarzweiß gefleckte Zikade am Licht (28.07.19): Allygus maculatus? --> Allygus mixtus

Hello Dr. Nickel, Thank you for clarifying the matter. I was concerned that the keys of Dr. Niedringhaus may be erroneous, I am not aware of any material from you, so i do not possess any books from you. I will definitely try to track down any books that you have published so that i can add them to my library. I judge diptera too quickly sometimes, so it is normal to overlook something. Identification by photo can be extremely difficult sometimes. I know this as a matter-of-fact. All is good. I ...

Zitat von »Herbert Nickel« Sicher A. maculatus. Ist tatsächlich noch nicht aus NRW publiziert, dürfte jedoch weiter verbreitet, wenn auch nicht häufig sein. Habe sie aus dem NLP Eifel. Herbert Hello Herbert Nickel, I use the keys of Dr. Niedringhaus which specify that A. maculatus should have two long blackish transversal spots at the vertex. I do not see the long black transversal spots on the first three photos. Do you suggest that the keys are invalid? I do not see a gender related note eith...

Fliegen auf dem Fell einer Kuh --> Deutsches Schwarzbuntes Niederungsrind

Hallo Frank, Ich spreche ein bisschen Deutsch. English ist meine Muttersprache. Vielleicht kann Jürgen später alles übersetzen? the flies in the photos are very small, so features of the flies are not visible for accurate determination. However, Muscidae are very common on cows. Two common species found on cows: Stomoxys calcitrans and Haematobia irritans. The frons of Stomoxys males and females is much bigger than the frons of the flies in the photo, so it is not Stomoxys. My guess is Haematobi...

Schwarze, borstige Fliege --> Raupenfliege (Phania funesta)

Hallo Karl, vide Phania funesta of the family Tachinidae. The strong marginal bristles on tergites 3 and 4 eliminate other candidates from the genus Phania, so i don't see a need to use a cf are you sure about the size? it seems more like 5 or 6 mm to me.Best Regards, John

Hello Jürgen and Thank you for the kind welcome message, I will try to use German language whenever it seems to be most appropriate. Afterall, Ich wohne in Berlin. Das ist Deutschland. Ich muss Deutsche sprechen I also have the Fotoatlas book. My wonderful Wife bought both of them as gifts. I am happy to have the Fotoatlas book because the identification book only has black-and-white drawings. yikes! sometimes i need more than a description as confirmation please let me know if you need to check...

Schwarzweiß gefleckte Zikade am Licht (28.07.19): Allygus maculatus? --> Allygus mixtus

Hallo Jürgen, Schöne Bilder, mein Freund Tut mir leid, Ich spreche ein bisschen Deutsch. English ist meine Muttersprache. Das ist Allygus mixtus (Gemeine Baumzirpe). Ich habe das Buch "The Plant- and Leafhoppers of Germany". Allygus mixtus = "vertex at fore margin mostly with six small black spots" whereas for Allygus maculatus: "vertex with two long black transversal spots". Best Regards, John
