I hope you get an answer, Bruce - I also have one in my unidentified files. |

Definately a fly of some kind - definately not a Psyllid. |

Hi Bruce,
It's probably Psilidae, Psila fimetaria which are 10-11mm. It should have a small black area where the arista joins the antenna, if you have another shot showing this you might be able to see it. There's another much the same but not as common.. I got it today too!  It's one I see most years.
Janet

So Psyllids and Psillids are not the same thing! I read that a particular Psyllid aphid species has been deliberately released into the wild in Britain in an attempt to control Japanese Knotweed (Fallopia japonica). Sounds like the old woman who swallowed a fly but apparently the Psyllid in question, Aphalara itadori, is very fussy about what it eats and if it can't find Fallopia japonica it will die.
Take care,
Paul |

They aren't, as you say. Psyllids are Hemipterans and Psillids are Dipterans. Surprised Matt didn't pick up on it! |

Psila fimetaria would appear to perfectly match my photos including the dark mark on the antenna that Janet mentioned. But I can't find any records in the whole of S W England.
Is there another very similar alternative or is it another case of under reporting? | | | |
