Netherlands, today, near lake I am aware of the difficulty of this species, but I was wondering if the black banded at the back of scutellum (seen in the 2nd picture) is something that is seen by more Helina species?

I think, this apical black spot is based on reflections and not relevant for determination. I cannot clearly decide whether there are presutural acr bristles (H. cf. impuncta) or not (H. cf. depuncta) - but I'm not a "Helinastyc" expert...
Greetings, Eric Kloeckner |

That sounds far more reasonable, as I have not noticed this before  I notice the H. impuncta/depuncta are one of the more easily recognized species in the genus. What makes these two so recognizable? Is it the light coloured thorax and orange femur/tibia combination?A very interesting (and common), but very difficult genus |
