Hello Holly, This looks to me to be a female Dysmachus picipes. However, I leave the final judgement to Quaedfliegh... Greetings, Ectemnius Edited by Paul Beuk on 07-11-2014 09:49 |

Thank you guys! May you explain the useful characteristics to identify the species? Federica And everything under the Sun is in tune, but the Sun is eclipsed by the Moon - Pink Floyd |

Take a look at an ovipositor (female's black chitin organ used to lay eggs) and those long hair on its underside, which are well seen on your first and last photo. Here it's even more visible: http://www.robberflies.info/keyger/images/800/Asilinae/Didysmachus/picipes_f1_01_COGG.jpg

So, is this the only species to have hair on the ovipositor? Thanks again! Federica And everything under the Sun is in tune, but the Sun is eclipsed by the Moon - Pink Floyd |

Nope  For instance D. harpax has them also, but little shorter and the shape of an ovipositor is much different. On the other hand a similar ovipositor have females of D. fuscipennis, but not so elongated as D. picipes and hair are barely visible. At first I meant to emphasize the most striking feature - the length of hair, which is characteristic for this species. Nevertheless you should always pay attention to the shape of an ovipositor. It's is a well distinguishing feature within females of Dysmachus, which is quite untypical for Asilinae.

The thing is that this is not an ovipositor of a Dysmachus species cerci should not be sticking out like this. In Dysmachus the bristles would cover the entire back of the mesonotum. This is a Machimus species. Maybe M. rusticus
