Hallo zusammen, P. vagabunda ist nicht möglich, z.B weil die Basicosta schwarz gelb ist. Pollenia pediculata männchen Freundliche Grüße John
Hallo zusammen, Familie Tachinidae, Unterfamilie Phasiinae. I'm not a Tachinidae specialist. I do not have experience with alot of genera from this family. However, it reminds me of Strongygaster globula You may want to ask Dr. Tschorsnig for an opinion about the genus. Best wishes, John
Hallo zusammen, Linnaemya sp (Tachinidae) Best wishes, John
Happy New Year, Jürgen. I hope that you can find many new species this year.
Zitat von »Jürgen Peters« Die Basicostae sind hell, also die übliche Lucilia sericata?
Hallo zusammen, I agree with Hydrotaea Best wishes and Happy New Year! John
Hallo zusammen, Sarcophaga (Sarcophagidae) is a better match. Best wishes, John
Hallo zusammen, Protophormia terraenovae male Protocalliphora azurea males have 3 ac bristles (think Lucilia but blue) and always show dusting on the thorax and abdomen. he frons is very narrow compared to Protophormia terraenovae males Protophormia terraenovae males lack the ac bristles and are not dusted. They also have a dark basicosta and infuscated calypters. The frons is wider than Protocalliphora azurea males Phormia regina have a conspicuous orange anterior thoracic spiracle, orange pedi...

Hi Jürgen, I apologize for my absence in the forums. I had covid which beat me up for a week and a half. I started feeling better and i caught the flu. The flu (Grippe) has really put me down for the count. I had to go to the Krankenhaus because my temperature kept climbing. I decided to go to the Krankenhaus when my temperature reached 39,7. I am not well right now but i am slowly gaining energy. I have been in bed most of the day for weeks. My stomach muscles are weak and i feel extreme pain e...
Hallo zusammen, The photos are very small but the basicosta is dark and the parafacialia are touching or nearly so. Calliphora cf vomitoria is a better match. Best wishes, John
Dear Jürgen, Protocalliphora = the basicosta and both thoracic spiracles are brown The species in your photo has a bright orange or yellow anterior thoracic spiracle Protophormia = both calypters are dark brown. The species in your photo has white calypters, at most the lower is slightly tinted Diagnosis: Phormia regina male Congratulations if this is a new species for you. I have not found a male yet. Best wishes, John
Hi Alex Thank you for the link to your observations. You have some very nice photos of this species. I have only seen it twice now. well, three times if you count the nymph. I imagine that eggs have been laid in autumn, so i will probably see more of it next year in Spandau. I found my specimen on a building. The same building that i found the nymph (my Hausartzt has an office in this building. I was waiting for my Wife when i found the nymph.) Hi Konrad I hope that you are doing well. I like ci...
Hi Ulrich, Fieberiella is a better match. I have not learned how to separate the species yet. I have a Fieberiella cf septentrionalis waiting to be examined. I think that florii has smaller white spots on the wings but morphology is often variable with cicadas. Perhaps someone with more experience will help you further. Dr. Nickel pops in from time-to-time. Best wishes, John
Hi Beate, I do not see a reason to disagree with your determination. immature (Jungtier) C. mildei stem from late July, so September is correct for such an encounter. Best wishes, John
Hi Jürgen, I think that the keys make them difficult. I am trying to examine more Fannia because the keys need revised to include photo identification. The keys that i am using require a specimen because one has to see the coxae. I know for a fact that certain Fannia are under or equal to 3mm, which is a good place to start keys. I am working on a review of European Fanniidae as a side project. I will focus on finding every species in Europe. Then we will have better keys to work with... Best wi...
Hallo zusammen, I have trouble thinking in German language whenever i am sleepy. I just woke up and i need my coffee. I should have posted more photos. My apologies for this error. I am still battling an illness and not thinking clearly. Anyway, i found a nymph at the end of Ocober. My Wife and i believe that the nymph is H. halys. I have been looking for Halys since 2017 but i have not seen it. I saw an adult on the same day as the nymph but i assumed that it was Rhaphigaster nebulosa (it is al...
Hallo Bernd, Nigma flavescens Freundliche Grüße John
Hallo zusammen, Ist das Halyomorpha halys? Berlin-Spandau, November 2022 Freundliche Grüße John
Hi Jürgen, D. repleta rechts Freundliche Grüße John
Hallo Jürgen, Calliopum simillimum (von Foto 2) Freundliche Grüße John
Hallo Beate, 1. Anthomyiidae Männchen 2. Coenosia Weibchen 3. Anthomyiidae Weibchen 4 Stomorhina lunata passt 5. Calliopum aeneum/simillimum bleibt 6. Tachina fera passt 7. Delia Männchen (Anthomyiidae) Freundliche Grüße John
Hallo Thomas, Palloptera ustulata Weibchen (Pallopteridae) Freundliche Grüße John
Hallo Jürgen, Fannia Weibchen (vielleicht F. pallitibia) Freundliche Grüße John
Hallo Jürgen, Fannia Weibchen Freundliche Grüße John
Hi Jürgen, Fannia Männchen Freundliche Grüße John
Hallo Bernd, Platypalpus Art (Hybotidae) Freundliche Grüße John
Hallo Bernd, Neophilaenus campestris Freundliche Grüße John
Hallo Bernd, Acericerus heydenii Männchen Freundliche Grüße John
Hi Jürgen, 1,2: the darkened apex of the first costal segment is typical of D. repleta )photos 1 and 2) 3,4: I cannot see a reason to disagree with D. immigrans in photo 2. 5: difficult. I cannot key it from these photos and i have not examined a Drosophila with this morphology. I think about D. funebris but i really have no experience with D. funebris. You might wish to ask Jan Maca at diptera forum for an opinion (I think that is his name). Best wishes, John
Hi Volker, A good lateral photo is better than catching one and examining it. I have done this work in order to to enable a higher possibility of photo id. The terminalia looks very different in lateral view of the female abdomen. Simply train your brain to seek a lateral view of dark Calliopum. Also, simillimum has a very coppery shine on tergite 2 and a grayish mesonotum at various angles. Very different than the greenish shimmer of aeneum. Calliopum simillimum Best wishes, John
Hi Jürgen, I hope that you are doing well. I have been sick with some sort of sinus issue for two weeks now. Please be careful when you are out in public. Meantime, i have no doubts (photo 1 shows terminalia at a good angle) that she is Calliopum simillimum. I love these flies and Lauxaniidae as a unit. Wonderful flies! Best wishes, John
Zitat von »Herbert Nickel« Hi John, believe me: The alienus story is among the most complicated taxonomic stories among European leafhoppers. Greene focusses on Nearctic species and is not the most relevant here, though it is quite good. For the time being alienus in Europe is the large macropterous species that is not monophagous but takes any grass and migrates around and developes a late autumn generation in winter cereals. Hello Dr. Nickel, I had to use the Nearctic revision because i canno...
beute = Sarcophaga (Sarcophagidae)
Hi Thomas, Ja das ist Nematocera. Ich glaube Ptychoptera contaminata Weibchen Freundliche Große John
Hi Ira, 1. Coenosia Weibchen (Muscidae) 2. Anthomyiidae Männchen Freundliche Grüße John
Hi Jürgen, I see a darkened apex of the first costal segement, so it should be D. repleta. I have examined a very light brown male repleta before but i think that strong lighting against dusting creates a paler appearance. Best wishes, John
Hi Christine, I am not qualified to name a species from this genus. I apologize for my lack of experience. I can only suggest Aphis cf. grossulariae. I agree that the new photos appear to depict this species but i cannot say it with authority. Best wishes, John
Hallo zusammen, I appreciate the replies but I have already determined this species as P. alienus by genitalia of the male and of the female. vide Page 29 A Revision of the Nearctic Species of the Genus Psammotettix James F. Greene feturing male and female genitalia with descriptions includes alienus and confinis with a note about the aedeagus of nodosus Biedermann and Niedringhaus 2009 lacks female genitalia (note: alienus also has a 1.7mm hind tibia). Best Wishes, John
Hi Jürgen, D. busckii is quite distinct. I agree with D. busckii I have only seen D. busckii two times in five years here in Berlin.Spandau Best wishes, John
Hi Johann, I have not found a list for Deutschland but i use the lists from Italy and Czech Republic: Annotated Host Catalog for the Tachinidae (Diptera) of Italy https://www.zobodat.at/pdf/Stuttgarter-B…A_0305-0340.pdf Annotated Host Catalog for the Tachinidae (Diptera) of Czech Republic https://journal.fi/entomolfennica/articl…56/43505/125462 Best wishes, John
Hallo zusammen, simply follow the scutellum across the suprasquamal ridge to land at the basicosta every time (a diagonal line). Dear Chris, you can name it whatever you want to name it but the erect vestiture on t4 and weak tessellations on the abdomen are not correct for vicina. Not to mention the infuscated anterior spiracle and the frontal vitta more than two times as wide as a parafacial. Best wishes, John
Hi Christine, I think that Aphis epilobii is a better match than Myzus persicae. Best wishes, John
Zitat von »Jürgen Peters« Fannia?
Hallo zusammen, Bellardia viarum Weibchen. Sie ist sehr Schön Freundliche Grüße John
Hi Jürgen, The Lucilia sericata female is having a bad week (she looks rough and well worn). However, the sockets for the missing third bristles are well visible, the a preapical on f2 is well depicted by your skillful photography (nice job!) and the first flagellomere is well within the 3-4 times longer than wide range. Sometimes the basicosta is brown or very dirty yellow on worn-out species. Difficult to judge at times. The male fits best as Lucilia caesar. Best wishes, John
Hi Jürgen, you are correct: C. vicina Männchen October through January plus strong lighting can make even vicina basicosta look dark. Best wishes, John
Hi Jürgen, I have found a document with keys (in German language) and i have keyed it straight to Ectobius vittiventris. So i agree with you and congratulations! I have not found this genus yet. I am happy for you reference: Taxonomie der Bernstein-Waldschabe Ectobius vittiventris (A. Costa, 1847) (Blattodea: Blattellidae) und ihre Verbreitung in der Schweiz Best wishes, John
Hi Christine, Aphis gossypii is possible but i am not an Aphid specialist. Aphids are host specific or polyphagous. A. fabae is polyphagous but i do not know of them having yellow wingless adults. Aphis gossypii has been recorded on Capsicum (pepper plants) but i have not examined any Aphis species under a microscope to learn how to identify them. I cannot say more than Aphis sp. However, Aphis gossypii is a possibility worth exploring. Best wishes, John
