I was hoping I had kept this one, but I couldn't find it. Tried to key it from the pictures, but I don't see enough detail. First impression was Nemorilla, but it could be something else. Southeast Norway 18 July 2023.

Thanks a lot! Could I ask you: 3rd antennal segment is 1.55X as long as the 2nd. (If I measure from photo no. 2) The 2nd antennal segment is yellowish and the frons is also quite wide - could it be F. maculosa? Morten |

Females are very tricky, but abdominal pattern disagrees with maculosa, I’d say. Length of third antennal segment is sexual dimorph, as probably is yhe colouration. Are you sure you are citing female values ? Theo |

Thanks! You know this much better than me!. But yes - according to Tschorsnig key:Floralis: Females: frons 0.75 - 0.92x as wide as one eye; 3rd antennal segment 1.64 - 1.96x as long as the 2nd; 2nd antennal segment black to brown. Maculosa: Females: frons 0.90 - 1.06x as wide as one eye; 3rd antennal segment 1.23 - 1.71x as long as the 2nd; 2nd antennal segment yellow to brown. Morten |

Colouration supports maculosa, but vertex says floralis and third antennal segment looks loger to me. When possible, I prefer structural features above colours, which have a tendency to be more variable. But, ID based on males is always to be preferred in Nemorilla ! Theo |
