Hi, On 13 August, I came across the individual pictured below, which, although I am a complete novice, I would identify as Peleteria prompta, though I’m not entirely certain... Location: La Motte-en-Champsaur (05500 – France) Altitude: 2,100 m Approximate size: around 15 mm The fact that the black band on the abdomen is discontinuous does seem to fit Peleteria prompta quite well. I’d be very interested to hear what you think  Are there any other identification criteria that I might have overlooked?Have a nice day,  |

but also Peleteria rubescens. Prompta is an high altitude species. Theo |

Hi, I agree that both could fit, once we’ve ruled out the species with a yellow second antennal segment. That said, I don’t seem to be able to make out any dusting on the anterior half of the tergites… But perhaps I’m just not used to recognizing it, and it isn’t actually all that conspicuous. Also, it seems to me that the fact that the observation was made at 2,100 m could fit with the preferred altitudinal range of Peleteria prompta. What do you think? |
