hmm. I just noticed the size and there is a better match: Buchenblattlaus oder Wollige Buchenlaus (Phyllaphis fagi) Familie: Callaphididae (Zierblattläuse) Best wishes, John
Hallo Heinz, Wolligen Blattläusen (English: Woolly aphids) Familie: Aphididae, Unterfamilie: Eriosomatinae Eriosoma lanigerum = An Apfel Eriosoma ulmi und E. lanuginosum = An Ulmen If you have Apple trees somewhere nearby, then it is most likely Eriosoma lanigerum Best wishes, John
Hello Jürgen, I also agree with roeselii. I have alot of experience with what is supposed to be longiceps and i do not see a match with longiceps. For one thing, the pronotum of longiceps is most often very pale and it has black/dark colored punctures. The dark area on the corium is less intense or "indistinct". I have dissected two longiceps males that were dead on my window and the genitalia matches what is called longiceps. I have found them under bark of platanus trees here in Berlin every w...
Hi Beate, Cecidomyiidae. I do not have alot of experience with this family and i do not have keys and descriptions. Best wishes, John
Hello veryone, Thereva cf. plebeja note the dark spots between the eyes, which eliminates Acrosathe genus. Best wishes, John
Hi Jörg, immature Clubiona can be quite difficult to bring to a species level id as they often look different as adults. I think that Clubiona lutescens is a better match but immature spiders must be prefixed with confer (cf.). Best wishes, John
Hallo zusammen, Rhagoletis meigenii weibchen tip: alot of flies like to drink our sweat. The proboscis of Tephritidae is not designed for penetration. Best wishes, John
I meant to type Superfamily Eriocranioidea. I just got home and i typed too quickly I guess that i need a speeding ticket. I will correct it Best wishes, John
Hi Christine Thank you very much for finding a genus for this little creature. I have not seen the adults before. I will keep my eyes open. Also, i forgot about lepiforum website, which is a fantastic resource. I figured that it could be a Schmetterling oder Motte. You are wonderful, Christine. I hope that you have a pleasant evening. Best wishes, John
Hallo zusammen, Foto: Mai, 2017. Berlin, DE. I cannot find a match for this larva. Any tips? Best wishes, John
Hallo, Band 1-12: https://www.e-periodica.ch/digbib/volumes?UID=ihf-001 Diptera Tephritidae - Band 10 (1994) Merz https://www.e-periodica.ch/digbib/view?p…001%3A1994%3A10 Diptera Asilidae. Band 11 (1995) https://www.e-periodica.ch/digbib/view?p…001%3A1995%3A11 John
Hi Bernd I wish that i could say more but i do not study Sphaeroceridae. I can only suggest Gattung Crumomyia as a possibility. Try searching near Crumomyia nitida for a match. Best wishes, John
Hello Bernd, Familie Sphaeroceridae. Best wishes, John
Hallo Jörg, The hind femur and the overall appearance is a determining factor for me whenever i am in the field. The size of the spots on the abdomen are also a factor. I find it difficult to describe but there is a visual difference between the two species and i deduce it to be stoutness of body and the hind femur. Bristles on the hind femur are also different. I can see larger bristles in your photo which are smaller on X. abiens. The best photographic angle of these flies is lateral so that t...
Hi Jörg, I have photos of Chalcosyrphus nemorum male and a comparison photo of Xylota segnis female. Your photo contains a female Chalcosyrphus nemorum - the only other Chalcosyrphus recorded in Germany, to my knowledge, is chalcosyrphus femoratus and the femora are reddish orange. note the pale base of the hind tibiae on Xylota spp. edit: there are 3 other Chalcosyrphus recorded in Germany besides femoratus and none of them are candidates. I do not see a need for a confer. Also, the hind femora...
Hi Jörg, whenever i try to key it, i end up at Thaumatomyia, Chlorops or Chloropsina. I cannot see enough to continue with the keys, hence a specialist is required. Specialists have enough experience to skip keys and/or guess that features are present or not. You could post at diptera.info and send a message to Dr. von Tschirnhaus requesting a genus. Best wishes, John
yes, i see what you mean. I will look at keys whenever i have some free time. I only have one Chlorops species documented and it is larger than 3mm. I also have Thaumatomyia notata recorded, so i will look at those photos too. The only options that i can see are Chlorops or Thaumatomyia.
Hi Jörg I cannot get to my foto drive at the moment, i have to get my son to school. I will post some photos here later today and also send to you an email message Best wishes, John
Hallo Bernd, Ich hab keine ahnung ab jemand das aktuelle vorhandensein in Deutschland untersucht. Vielleicht wird es selten fotografiert. Es wird in nestern von Ameisen gefunden und auch unter steinen. Best Wishes, John
Hallo Bernd, Fischchen. Siehe Atelura formicaria https://www.researchgate.net/profile/Wou…a_Nicoletiidae/ http://fdickert.de/fischche/nicoleti/nicoleti.htm Viele Grüße John
Zitat von »Frank Sudendey« Zitat von »JohnEs81« ... in your low-quality photo ... In der heutigen Zeit sollten tatsächlich bessere Bilder möglich sein, auch dann, wenn man nur wenig Geld für eine Kamera ausgeben möchte. Ich meine das gar nich böse, aber selbst ein Handy bekäme das besser hin BG. von Frank well said, Sir. I am not trying to be disrespectful but that is awful quality. Also: Tut mir sehr Leid. Deutsch ist nicht meine Muttersprache
Hello Karl-Heinz, which Steatoda do you propose as a possibility? The only Steatoda that bears any resemblance to the spider in your low-quality photo is S. triangulosa I have altered a photo of mine to look similar to your photo. The female in my photo is pregnant (Schwanger). Difficult to id with any certainty. welche Steatoda schlagen Sie als möglichkeit vor? Die einzige Steatoda, die der Spinne in Ihrem Foto niedriger Qualität ähnelt, ist Steatoda triangulosa. Schwierig zu Identifizieren. Be...
Hi Jürgen, fantastic photo I have not seen the babies forming such a mass before. I always find them running around the nursery. I have a photo of a baby Listspinne attempting to balloon. Best wishes, John
a-ha! I found the photo. She is at the nursery with her babies. :-)
Hello everyone, Pisaura mirabilis is my favorite spider. Thank you for sharing your color variations Angelika und Reimund I have an old compact camera photo of a golden female with very little markings. I will try to find this photo and add it to the thread. Best wishes, John
Hi Jürgen, very nice photos yes, that looks quite painful. I hope that i do not get bitten by that one. Another spooky biter is Stomoxys. I got a look at that proboscis in my microscope. I would imagine it is quite painful as well. I will try to find some different Tabanidae next year. Hopefully i can accomplish this task and revisit our conversation
Hi Jürgen, Thank you for updating this post. Much appreciated. Nikita's opinion supersedes my opinion regardless, so it is nice to share the same opinion. I like Nikita. He is very nice and very knowledgeable. I try to keep in contact with him and also Dmitry Gavryushin from diptera.info. Best wishes, John
I have yet to find these flies where i live. I am surprised that you find them in November. I guess i have to venture out to see if i can find some around Berlin.
Hi Jürgen, I just remembered that i have seen one other Tabanidae where i live. I made a photo with a 70-300mm telephoto lens, which i was using to photograph birds. I saw a few flies out on the lilly pads so i snapped a few photos. I think that it is a Tabanus sp. but i have no experience with this family. I would have to examine the fly for an id. I gave up on an id. I made this photo in 2015. I was photographing baby Mallards (Stockenten). Best wishes, John
Hi Jürgen it tried to bite you through your jeans? that is nasty. I know what you mean about pursuit. The H. pluvialis sometimes stalk me like a blood-thirsty shark. I usually just get out of the area. Very annoying. I cannot imagine the larger Tabanus species following me around. speaking of jeans, i remember one day i was kneeling on a pathway to photograph a Labyrinth spider in its web and i felt a tug on my jeans like someone was tugging at my pants with their fingers. I looked down and saw ...
Zitat von »Jürgen Peters« - Chrysops caecutiens (very annoying...) - Chrysops relictus - Haematopota crassicornis - Haematopota italica - Haematopota pluvialis (also annoying) - Haematopota subcylindrica - Heptatoma pellucens - Hybomitra micans - Hybomitra muehlfeldi - Tabanus autumnalis - Tabanus bromius - Tabanus maculicornis - Tababus sudeticus (very impressive) Impressive list I have no experience with this family. I did not know about Philipomyia aprica. I am starting to download documents...
Hi Jörg, I am attaching a photo of the development stages of Zygiella x-notata for learning purposes. Zygiella do not have hairs covering their head at any stage of development. The abdomen of babies/spiderlings is typically black/dark blue with white marks I agree with L. cornutus from experience. Your new photos of the babies is fantastic! Nice work Best wishes, John
Hallo Jörg, I really enjoy viewing spiderling photos. Your photos are great. I would like to find alot of spiderlings and publish a book someday. Some of these baby spiders are absolutely adorable. Two of my favorites are Pseudeurophys lanigera and Platnickina tincta. I've attached a photo to show how cute they are. I am a big fan of baby spider photos Best wishes, John
Hi Bernd, the wing venation does not fit with most Tipula. I failed to start with rule number 1: examine wing venation. The closest match that i can find by wing venation is Angarotipula tumidicornis. I use the following site when trying to id any Nematocera: https://eskoviitanen.fi/tipulidae_wing_e.htm you should definitely seek out a Tipulidae expert, such as Oesterbroek for an opinion. Best wishes, John
well Simeon is a Nematocera specialist (as well as Arachnologist), so you have a trustworthy opinion. I'm a specialized Brachycera and limited spider enthusiast. I specialize in Calliphoridae/Polleniidae but i am able to help with Muscidae, Fanniidae and a small amount of Anthomyiidae. I do focus alot on Helina and Phaonia genera from Muscidae. The only Nematocera group that i can regularly identify with accuracy is Nephrotoma. I have trouble with Nematocera so i only id by male genitalia. Thank...
Hi Bernd, have you asked about Tipula paludosa? it seems to match quite well but i am not a Tipulidae specialist and i only id them by genitalia. Best wishes, John
Zitat von »Urs-Peter« Thanks John, From some part - at the moment i can't remember - it was determined as Tabanidae: Philipomyia aprica best wishes Urs-Peter I looked at that species and it appears to be a good match. I do not study Tabanidae. I'm just trying to investigate the unanswered posts in the forum. I have only seen Haematopota pluvialis in Germany. Honestly, i have not encountered any other Tabanidae species here. Interesting. Atleast you have an id, so we can close this thread. Best ...
Hello Jorg, xylota: hind tibia is said to have 20% of the base yellowish-white. the species in your photo has a black base. chalcosyrphus: abdomen has four large and rectangular yellow or gray spots versus smaller yellow spots of abiens. I lean towards Chalcosyrphus nemorum but you would have to ask a Syrphidae specialist since i would require a specimen or a view of genitalia. Best wishes, John
Hello Urs-Peter, If i were to encounter this species, then i would start examination at Tabanus bromius. it looks quite similar to your photo. https://www.spessart-fliegen.de/diptera/…us_bromius.html Tabanus species seems to be correct but i do not study Tabanidae. Best wishes, John
Hello Beate, Choerades fimbriata oder fulva Best wishes, John
Hello Bernd, Dryomyzidae Best wishes, John
Hallo Thomas, photo quality is not good enough for a species level identification. However, it is clearly a member of the rudis group and i suspect it to be either rudis or angustigena. Best wishes, John
Hi Jörg, confer Thaumatomyia notata (Meigen, 1830). You could ask Dr. von Tschirnhaus for an opinion. T. notata is quite common in autumn/Herbst. I find them often in October at a local park. Best wishes, John
Hi Jürgen, I sometimes forget that there is confusion with these species. Let me clarify my position: I believe that pruinosa and pallitibia could be one of the same or a synonym. I spoke with Nikita Vikhrev about this topic many years ago. Stephane Lebrun helped me with identification of pallitibia many years ago but i turned to dna for an answer due to confusion. Rozkosny has keys to females (1997) and he lists pruinosa as having biserial pre ac and pallitibia triserial pre ac. If you study th...
Hi Jürgen, Theo is a Tachinidae specialist, so that works out well. I cannot see a mismatch but i am not a Tachinidae specialist. Nice find! I have not seen it here in Berlin and Tschorsnig documents state that it is rarely seen outside of a mailaise traps and hosts are listed as unknown. Congratulations, John
Good morning Jürgen, Fannia pallitibia weibchen. I am positive. John Carr is very good at placing flies into a family. I have always liked John. He is a very nice man and very knowledgeable. He is also a computer programmer. Meantime, try to keep an eye open for the male. Although, i have only seen the male in August and far from where i found the females. I actually found a female trapped in the stairway of my flat (Treppenhaus). The male was found the following year in shady woods about two mi...
Zitat von »Jürgen Peters« How about Paracraspedothrix montivaga? Good morning Jürgen, I had to get my morning coffee before looking at my photos Microsoma is definitely not a match! Flight period is off as well. I will add a photo and you will see why... oops! I think that Unterfamilie Exoristinae is a perfect fit. I looked at your suggestion and i quite agree with Paracraspedothrix montivaga and the flight period is also a match. You will need a confirmation from a Tachinidae specialist. I do ...
Hi Jürgen, I have recently identified a Tachinidae from my own photos dating back to 2021. My subject turns out to be a female Microsoma exiguum. She looks remarkably similar to your Tachinid. I will check my photos tomorrow for confirmation, unless you can find a Tachinidae specialist to help you in the meantime. Best wishes, John
Hi Jürgen, Fannia. She looks similar to pallitibia. Unfortunately, i shut down my work computer for the night. I have to go to bed soon. I get up at 4:30 AM on weekdays. Anyway, i will check my microscopic photos of F. pallitibia tomorrow for confirmation or key it out to a better match. Best wishes, John
Hallo Bernd, D. melanogaster ist möglich, aber D. simulans ist sehr ähnlich. Sie mussen ein Drosophilidae expert fragen. wenn sie diese Fliege gefangen haben, dann können sie sie mir senden Best wishes, John
