i agree with Dima. Hemiptera > Aphidoidea > Aphidiidae |

...rather Hemiptera > Aphidoidea > Anoecidae, but not shore. |

The short antennae suggest Anoecidae or Pemphigidae, but as always with aphids, it would help to know what it's on.

Hello, Damned, it is the third time I see this Aphid in a few days. A clear whitish belt and black pterostigma. And nobody can give a clue... Edited by pierred on 14-09-2007 21:25 Pierre Duhem |

Is it not a psyllid? The antennae look a little short for an aphid. |

I think John is completely right! It does look like a psyllid. But what subfamily/genus/species? I will ask around to try to find out more! Jan Willem |

I'll stick with Aphidoidea on this one - the hind legs are not enlarged enough for Psylloidea, and the antenna look to be 7-segmented, not 10 which is usual for Psylloidea. The fore-edge of the wing is also rather straight. Psyllids normally have a more convex costa.

Hello, Here is my picture of (what I think being) the same species. Maybe it can help. pierred attached the following image:  [76.29Kb] Pierre Duhem |

Definitely not psylloid, neither the first nor the second picture.

Dear dipterologists: this is one of those Anoecid aphids that are neither psocid nor flies (even in English) but are food for numerous flies. They multiply in big numbers on grass roots and now they are looking for their winter hosts (usually a shar so thy are the bigest part of early fall air pnacton and they can be verywere now... |

Yes, I withdraw my psyllid suggestion. I've taken the picture home and compared it with the key, and the wing veins are wrong. It doesn't have a cell cu1 that seems to be everpresent in psyllids. John Bratton |

well... I will install the total confusion  this is a Psyllidae (i'm talking about the first photo). According to Dra. Diana Percy, expert on psyllids: "This is a psyllid. Family Triozidae, superfamily Psylloidea. Aphids usually have 2 cornicles - small protrusions on the back of the abdomen, see: http://www.ipm.uc.../?printpag" Edited by jorgemotalmeida on 20-09-2007 18:28 |

Think my vote goes for aphid. It seems to have a single proboscis under the head which neither psocids or psyllids have. I think the cornicles are small (they are on some aphids) and hidden by the wings. Just noticed I've got a pic of the same bug I think- definitely an aphid. brian V.  |

fraid not Jorge,- just had a look at the original shot and it has what appears to be tubes on the side of the abdomen which I think lead to the cornicles even though the cornicles are not visible. AFAIK this is typical for aphids. brian V. I've played with and cropped the original shot for more detail.

That's some detail Brian! Clearly an aphid. (As is the first photo!)  Tony ---------- Tony Irwin |
