I can start with the family: Cicadellidae.

Hello! Paul Beuk wrote: I can start with the family: Cicadellidae. I'm happy that this time I can contribute something (normally only posting questions)  : it should (hopefully) be Acericerus heydenii (Cicadellidae, Idiocerinae), a species living at maple (Acer) and often overwintering at/in buildings. I had found this species (confirmed by Dr. Herbert Nickel) often here in Germany at our house in the last weeks.

Hi J?rgen, I am nicely surprised to hear the sp. name from this family. I checked the dutch sp.-list and it's more than a thousand of species! Another Acericerus sp. is Acericerus vittifrons, 'the brother' of Acericerus heydenii. Do you know if they differ a lot? I found the Cicade on a bridge in the Amsterdam Forest. Thank's a lot for your reaction! Robert Heemskerk Edited by Robert Heemskerk on 09-01-2007 12:27 |

Hello, Robert! Robert Heemskerk wrote: Another Acericerus sp. is Acericerus vittifrons, 'the brother' of Acericerus heydenii. Do you know if they differ a lot? I have never seen vittifrons here, only ribauti (which differs quite a lot) and heydenii, so I'm not 100% sure. Do you understand a little bit German? (Otherwise I'll try to translate later.) Dr. Herbert Nickel, an accepted authority on cicadas and especially this subfamily (he had established the species A. ribauti) has explained the diagnostic attributes of A. heydenii here: http://insektenfo...eadid=4993 It is possible that the "eye glasses" marking on the pronotum is typical for A. heydenii (not visible on your photo - as the other mentioned attributes of the face are), but he wanted to take a look at his collection to verify this. Here is another typical pic of these "eye glasses" on A. heydenii: http://insektenfo...entid=9423 Edited by Juergen Peters on 10-01-2007 08:25 Best regards, Jürgen -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Juergen Peters Borgholzhausen, Germany WWW: http://insektenfo... -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= |

I watched the 'eye-glasses' marking on the pronotum. On my photo, the cicade seems to have 'gleichseitige(hard to see) flecken' under the 'Thyridialflecken (A. heydenii got them above this black spot) When I looked at the cicade Idiocerus herrichi on: http://gallery.kunzweb.net/main.php?g2_itemId=279 It seems that such cicade got these black triangle too (under the Thyridialspot) that gives me the conclusion that I am further from home, know a bit more about these group of cicade. A good shot from the face of the cicade can give some help to identify. thanks for your links and help! Robert, Edited by Robert Heemskerk on 10-01-2007 11:53 |

Robert, Hello Robert, for Idiocerus herrichi: it has a few differences in the wing venation compared to Acericerus sp., and your photo looks clearly like Acericerus. For A. vittifrons: it seems to be a bit tricky to differentiate this from A. heydenii if you do not see the "face". If the size you give is correct, it should be A. heydenii (and I think Juergen is correct with this, but my opinion is of limited value here ;-) ), A. vittifrons usually does not reach 6 mm (about 5,5).

Thank you very much for your comment Martin. I will call it A. heydenii and put a questionmark next to it. The size is not hard, just a valuation of mm.. |
