Thank you Paolo, sorry I forgot the location and the date: Val d’Arda (PC), N Apennines, 7 August 2020. I hope the particular site within Val d’Arda - a 100 metre stretch of mixed earth and rock banking alongside a high-level single track road - is as productive next year! Just by good luck I found one rock partly covered with small rock flakes where as many as four different chrysidid species would come to hide and rest overnight without being scared off by me staring at them just a few cms away!
Best wishes, Brian
