Can anyone say for sure what species these soldierflies are, photographed mating and after separating? The spiky thorax and wing patterning/ body colour etc seem similar to Beris vallata images I have seen, but there may be some more definitive characters I'm missing...

Hi Nick, not vallata, that has an orange abdomen, which would show through the wings. This is either morrisii or chalybata with all yellow femur and tibia; wide frons on the female suggests chalybata. Tim |

I should add that the black hairs on the male's thorax also indicate chalybata. Tim |

OK, many thanks Tim for the pointers to the key details. Yes, B. chalybata looks just right. At least I got quite close! Nick Upton - naturalist and photographer |
