Zitat von »Bernd Cogel« A new species for me. congratulations I am happy for you. Dear Michael, I have found them only in May. I noticed that Bernd mentioned 25.01.25, so i checked my records and i only have it recorded as early as May. Thanks for the tip! I will look for them in February and March. Perhaps i have overlooked them all of these years...
Hi Karl, Tachinidae. I think that it belongs in subfamily Tachininae. Somewhere near Linnaemya. Best wishes, John
Hi Karl, I cannot think of a Tachinid that one could mistake for Cylindromyia, so Cylindromyia must be correct. The fly certainly resembles Cylindromyia. However, rufipes is absent from the central european keys. I had to search for other keys and i came across Cerretti, which is written in Italian. I know a little Italian and i think that i understand the following description: femori e tibie di colore arancione o rosso addome interamente o quasi interamente nero. my attempt to translate into E...
Hi Karl I have to remain at Lucilia sp. because i cannot see the necessary features to bring it to a species level. Best wishes, John
Hi Bernd I agree with your determination. Best wishes, John
Hi Karl, I am not convinced that it is a Tachinid. I cannot think of a Tachinid with such an appearance and small size. I wonder about Oplisa tergestina (Rhinophoridae). Best wishes, John
Hi Konrad, I do not have enough experience with Lepidoptera to id this Raupe with certainty. If noone has an opinion about Camptogramma, then i am happy with Geometridae. I have not seen any cicadas this winter but i have not had time to go out and look for them. I have been very busy lately. I am happy for you I have not recorded Tremulicerus fulgidus, so it is a nice find, my friend I hope that you have a nice day, John
Hi Karl, Lydella, Admontia and Exorista are within Unterfamilie Exoristinae. So, yes, i am saying that it is a fly within Unterfamilie Exoristinae. I have only recorded Eurythrocera, Istocheta, Medina, Meigenia, Ocytata, Pales, Phorocera, and Spallanzania from this Subfamily. I have not seen this fly before and keying it would cost many hours and i could end up at the wrong genus. I have to leave it at Exoristinae but it is not a fly of any of the genera that i have recorded. Best wishes, John
Hello everyone, I have checked the pages at Lepiforum against all of the Geometridae species that i have photographed in this park and the only similarity is Camptogramma bilineata https://lepiforum.org/wiki/page/Camptogramma_bilineata I do not know if this is a match other than general appearance, since i am not a Lepidopterist. I find Camptogramma bilineata very close to this birch tree almost yearly, so maybe it is a possibility. i can show a photo of Camptogramma bilineata from this immediat...
Hi Karl, I do not know a genus and it is difficult to key. I have looked at alot of photos lately and i wonder about Lydella. Alot of features seem to match Lydella, so it must be somewhere around this genus. Best wishes, John
Zitat von »Jürgen Peters« Phania funesta sollte stimmen. Thank you Jürgen
Thank you Konrad how are you? i remember our cicada conversations. You are a nice man. I appreciate your opinion. I am happy to know a family for this larva. I can look at all of my Geometridae moths and butterflies and see if any match the larava at the Lepiforum. Maybe i can deduce a species from it but honestly i am happy with a family Best wishes, John
Thank you Bernd I am happy with Geometridae Best wishes, John
Hello friends, Foto: August 2016, Berlin I am hoping that someone recognizes this green larva that i found hanging from a Birch (Betula) tree. I do not know if it is Lepidoptera. Maybe someone has a tip. Thank you , John
Hi Karl, I do not have time to examine the fly but it looks more like Simulium species (Nematocera -> Simuliidae) based upon the antennae. Simuliidae are difficult to id because i cannot find keys. I have only identified S. angustipes via genitalia. I think that Simulium argyreatum looks similar but i cannot confirm it. Best wishes, John
Hi Karl, try Phania funesta. I am out of time for now, so i cannot confirm it. I will return whenever i have free time... Best wishes, John
Hi Karl, Stechmücke (Culicidae): a male (= plumose antennae) Mosquito. I think that genus Aedes is a possibility. Aedes vexans is common but i am not a Nematocera specialist. Best wishes, John
Hi Karl, I agree. I have both P. atra and P. leachii documented. P. leachii has yellow fore- and mid femora. The hind femur has a dark ring near the apex. Best wishes, John
Hi Karl, Musca domestica male. Best wishes, John
Hi Jürgen, I have sent a private message to you. I noticed a problem with the forum software, so i wanted to bring it to your attention. Best wishes, John
Hi Karl, I have not examined or photographed a Macquartia sp. I am not sure why i have not encountered Macquartia yet. Assuming that Macquartia is correct, then Macquartia grisea is a good match, especially with those long legs. Best wishes, John ps: Weibchen
Hi Karl, using "Updated taxonomic keys for European Hippoboscidae (Diptera), and expansion in Central Europe of the bird louse fly Ornithomya comosa (Austen, 1930) with the first record from Slovakia": tarsal claw simple -> wing with one or more cross veins -> Wing distinctly crenulated and tinted, with two cross-veins; head not broader than long -> Hippobosca. veins of wings dark pigmented; scutellum white in middle, dark on sides -> Hippobosca equina. Best wishes, John
Hi Karl, I can only add Sarcophaga species because females cannot be identified by photo (Dr. Pape). Best wishes, John
Hi Karl, see Psilidae. I think that Psila cf fimetaria is a good match. Best wishes, John
i mean the name Tachina, such as Pelatachina, Xylotachina et cetera. As Tachina genus goes, magnicornis legs are quite dark. However, i have been looking through some photos and i wonder about Blepharipa pratensis. The keys to Tachinidae by Tschorsnig are quite difficult because they require a specimen. One must work from the top of the keys to over half of the species just to arrive at a tachinid as simple as Cylindromyia. I have no time to key this fly but it looks similar to Blepharipa praten...
Hi Bernd, Hi Jürgen, Männchen Best wishes, John
Hi Jürgen, Pollenia angustigena Weibchen Best wishes, John
Hi Jürgen, Pollenia angustigena Weibchen Best wishes, John
Hi Jürgen, Pollenia angustigena Männchen Best wishes, John
Hi Jürgen, Pollenia angustigena Männchen tip: notice the av hairs between av bristles on the hind tibia. The hairs are growing downward, whereas the hairs are erect on rudis males/ Best wishes, John
Hi Karl, I wonder if Pinus pine trees grow near your Obst-Kräutergarten? mein Deutsch ist nicht so gut aber gibt es Pinus Nadelbäume in der nahe? Best wishes, John
Hi Manfred, Ja das ist eine Kohlmeise. Ich habe so etwas noch nie gesehen. Ich denke es ist sehr selten so etwas zu sehen. Best wishes, John
Hi Karl, the central hairs of the abdomen are decumbent / lying down, so the fly matches the keys to Eliozeta. I think Eliozeta cf helluo Best wishes, John
Hi Karl, Tachinidae. The fly has recently emerged from its pupa. I cannot place it but it could be a Tachina or something similar to Tachina. Best wishes, John
Zitat von »Jürgen Peters« Hydrotaea I have tried to find a species but no luck yet. We shall keep it as Hydrotaea Weibchen for now... Best wishes, John
Zitat von »Jürgen Peters« P.S.: Onesia floralis seems to be Onesia sepulchralis meanwhile (?). yes that is correct. floralis is a synonym. I do not know which is the preferred name. I will ask Dr. Pape the next time time that i write to him, since he is a taxonomist. Best wishes, John
Hi Michael, Ectophasia crassipennis is known to have a darkened abdomen but it is rare. I do not see a reason to suspect E. oblonga, so i will agree with this determination and add Weibchen to the conversation. edit: i meant to type Männchen. sorry for the error. Best wshes, John
Zitat von »Michael Stemmer« By the way: "chaetotaxy" is a new term for me. Hi Michael the term was proposed by Oosten-Sacken in 1881: https://www.zobodat.at/pdf/MitthMuenchEn…5_0121-0138.pdf I respect the work of historical figures, so i use the term in place of bristle arrangement. I learned the term form Dr. Knut Rognes. I do not know of an equivalent German word other than Behaarung, so Die Beinbehaarung passt nicht zu Pegomya - ist das richtig? Best wishes, John ps: if you need to see photo...
Hi Michael, costa section2 fits notata, so i see no reason to disagree with this id. Best wishes, John
Hi Michael, Phaonia pallida male. leg chaetotaxy is not correct for Pegomya. Best wishes, John
Hi Jürgen, seems to be a Bellardia vulgaris male but i will give it another look tomorrow. I must log off soon. also, i agree with Melinda gentilis female for the second photo Best wishes, John
Hi Jürgen, the bend of the m-vein is too much of a hook to be Melinda and not enough of a hook to be Calliphora. Protocalliphora have a sharp corner at the bend rather than being rounded. Onesia floralis female. Best wishes, John
Hi Jürgen, difficult to judge, so we must stick to the basics: bend of the m-vein restricts us to Bellardia, which can be confirmed by the presence of 1+2 ia. I cannot bring it to a species level with certainty from this single photo but it should be B. vulgaris female with 2 pv on the foretibia (not common but it is known to have two.) Best wishes, John
Zitat von »Jürgen Peters« Bellardia? Hi Jürgen, ! Bellardia vulgaris female. Best wishes, John
Hi Jürgen, Onesia floralis female Best wishes, John
Hi Jürgen, 3 post ia eliminates Calliphora and Bellardia. The bend of the m-vein is not sharp enough to be Protocalliphora, so we are left with Melinda gentilis male (width of the frontal vitta). Best wishes, John
Zitat von »Simeon Indzhov« Ist das nicht einfach Calliphora vomitoria? Ich meine, einen kupferfarbenen Bart zu sehen. Simeon yes but be careful judging pale hairs on the back of the head, since many genara of Calliphoridae and Polleniidae have pale hairs on the back of the head (which can appear to be golden in certain lighting and in some cases, extend into the cheek area like Onesia austriaca). Thank you, Jürgen, for the illustrative photo of Onesia with the strong golden hairs on the back of...
Hello Jurgen and Karl, so i have done some research on Eliozeta and Clytiomya today (and the wing venation of Clytiomya is not different from Eliozeta). Honestly, the two cannot be separated by this photo without the opinion of a specialist. I see some very dark or thick looking hairs in the middle of the tergites, which indicates Clytiomya. However, this photo is not clear enough for me to judge the hairs accurately. My photos of Clytiomya make judging the hairs very easy. For a better understa...
yes, Jürgen is correct. I have a male Clytiomya continua documented. I looked at my photos and the wing venation does not match. Eliozeta is correct but i do not have time to key it today. Best wishes, John
