I don’t have a good photo of the area just posterior to the anterior thoracic spiracle but I suspect that those bristles might be visible in a dorsal view. If they would be, I don’t see them. Assuming that there are no bristles there, this appears to key out to Lonchaea using both the Manual of the Nearctic Diptera and the Lonchaeidae Online keys: setulae on lunule, one bristle on katepisternum (as seen in ventral photo), aristae bare. I’ve included a poor photo showing the fully extended ovipositor in case it’s useful. I’d really appreciate input from those with more expertise than me. TIA Edit: fixed the link to the lousy ovipositor photo Edited by Steve Scholnick on 10-10-2022 04:43 |

Ah - North American Lonchaeidae - a rather neglected group in recent years! Anyway Steve you are quite correct this is a female Lonchaea spp perhaps near to Lonchaea albidala McAlpine although its almost impossible to tell without having the specimen under a microscope. You don't still have the specimen by any chance?? best wishes ............. Iain http://lonchaeida...cies.info/ Iain MacGowan |

Thanks Iain! I'm afraid I let her go after I was done taking photos – I keep insects confined to a spectrophotometer cuvette when photographing indoors. What would you need to see under a microscope to make a species ID? If it's an external feature, I may be able to photograph it if I catch another one Thanks again. Steve |
