This is quite a small doli 1.3mm body length found on top of leaves in my garden in Northern Illinois. We live in a forested area and the garden gets some sun, but mostly shade. Any help with ID? Hmmm can't get the photo to post... It is smaller than 200K and the file name has no spaces... so I posted all the full resolution images to flickr and provide the link below. Help posting directly would be appreciated.  ps mid by bugez1, on Flickr  ps 001 by bugez1, on Flickr  ps 1 by bugez1, on Flickr  ps 1 by bugez1, on Flickr  ps 1 by bugez1, on Flickr  ps1 by bugez1, on Flickr Edited by Keith Short on 09-06-2013 02:00 |

Hi Keith, what is the equipment you have to produce these beautiful pictures? |

tyrolean, I use photo stacking and a rig of my own creation. My equipment is described here http://www.photom...hp?t=12851 and here http://www.photom...hp?t=13427 Optics wise I use a 10X microscope lens with a 200mm fixed focus camera lens as the "tube lens". For processing the image stacks, I use Zerene Stacker. The light I use with the microscope lenses is described here. http://www.photom...hp?t=15788 I became interested in flies because of my love of the stacked photo process and the amazing features on insects that the photos reveal... Kind regards, Keith |

hi Keith, thanks for posting links to your equipment! Now I understand why my pictures are different!  There's no way to install such gear in my workroom ... Keep up the good work! Very impressive! |

tyrolean, Many thanks for the kind words. I have migrated toward smaller flies and ID is difficult as few have studied such minute subjects. Kindly Keith |

Nice photos. Unfortunately, female. At a first glance, Sympycninae (?Sympycnus), but such a small doli can be ID by a male only.

Igor, Many thanks for the tip on the ID. I have several other similar flies, I'll check to see if any are male and post the photos. Kind regards, Keith |

I think this is the male as it is nearly the same size 1.3mm, was found in close proximity to the female, and looks right. Found in Loves Park, Illinois in my flower garden. Females were perched on the tops of leaves. Males hovered about. First the head  ps 1 by bugez1, on Flickr  ps 1 by bugez1, on Flickr Then the male parts  ps 1 by bugez1, on Flickr a stereo of the male parts  male organs ventral by bugez1, on Flickr Thanks for help with a genus ID or species if possible |

I'd say Sympycnus. Hind tarsus is often modified.

Robinson (1964) keyed five species of Sympycnus from eastern United States, of which lineatus Loew is the best match to your flies. |
