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 am pleased to know that the keys are working.
Dear Jürgen,
Now that i know Dr. Nickel is in the forum, i will keep quiet with cicada queries. I am just an amateur. Although, i am happy to know that the keys work. :)

Best Wishes,
John
ps i'm going to search for books by Dr. Nickel now for a better well-rounded education about cicadas.

Sorry, I did it too quickly. It is a dark specimen of mixtus. A. communis can almost certainly be ruled out, because it is usually less dark.

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.

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 either. I typically key a species before dissecting genitalia and i find that the keys work before considering genitalia. I ask you because you do not specify a reason for this determination other than you stating that you are certain of your identification.

Hello Jürgen,
I hope that you find Orientus ishidae. It is a very pretty species.


I almost forgot about our moth conversation. Here is a photo of the Laothoe populi that i found last night. Such a pretty species, oder?
I am logging off for the night. I have a physical therapy appointment in the morning for my shoulder injury. I hope that you have a pleasant night.
Best Regards,
John :)

Hello John,

thanks a lot for your help. I have some older books on Cicadas, mostly with black and white drawings. I do not use them very often (would have to take them from under a large pile of other books... :rolleyes: ). I generally do not often use keys, because I mainly have problems with the technical terms. And I do not collect insects, only take photos in their natural surroundings (not all very natural, if you consider the UV-lamp in the garden ;) ...). On most of my photos not all relevant characters are visible, and because my interests are very general, I often do not know while in the field finding an insect, what details I should portray.

BTW: Orientus ishidae (nice picture!) is on my list of species I hope to find one day...

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 a cicada against the keys. I am happy to help.Regarding color, i often find cicada that are lighter or darker than the photos in the Fotoatlas. Sometimes it can be the difference between a male and a female. Other times, i find, it can be first or second generation differences. Using photos alone can be quite difficult because of matters like this.

Also, if you flip to page 206, then you will see Orientus ishidae. I just found this species last night. I will attach a photo for you to see.
I'm happy to be a part of the forum now. I will try to help id as much as possible.
Best Regards,John

Hello John and welcome to the forum!

Tut mir leid, Ich spreche ein bisschen Deutsch. English ist meine Muttersprache.

No problem, you can write in English here, most of the forum users will understand English. I have to say sorry, because MY English may not be very good...

Das ist Allygus mixtus (Gemeine Baumzirpe).

Thanks for the ID. Allygus mixtus is rather abundant here (see pics below). But judging from the photos in the "Photographic Atlas of the Planthoppers and Leafhoppers of Germany" (no key there, only photos) I thought, this animal was too dark for mixtus.

Hallo Jürgen,
Schöne Bilder, mein Freund :) Tut mir leid, Ich spreche ein bisschen Deutsch. English ist meine Muttersprache. :panic:

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
