Ik zou graag willen weten welke soort dit is.
Het gaat om deze waarneming: https://waarneming.nl/observation/255072661/.
1 Veldsikkelwants - Nabis ferus imago
datum: 2022-09-19
locatie: Waspik (NB)

Ik zie in de beschrijving dat de beharing van de lederhuid nodig is om een onderscheid te maken tussen Nabis pseudoferus en Nabis ferus. Kan deze soort beter gezet worden als Nabis ferus/pseudoferus (nieuw toegevoegd worden als verzamelsoort) of Nabis spec, of compleet als Nabidae indet?
Ik ben geen expert, en maak nog veel fouten.

Ferus/pseudoferus with tendency towards ferus.

Thank you very much. I wonder if we can differentiate N. ferus vs N. psuedoferus, as I do have some other images. I wonder on what characteristics the accepted observations have been accepted and how mine "not yet accepted" can also turn into one  ;D

Ferus is broader, lacks dark spots on the exocorium, lighter in colour (but this is variable) and some pseudoferus have somewhat shortened wings - but not as much as rugosus or brevis, remaining able to fly.

Thank you very much! I added some extra pictures. I believe the spots on the exocorium (or the lack of) require quite a good photo, so might still not be a certainty. Something to watch for the next time  :right: thanks again.

The spots are actually well visible when present, even on a less good photo :) yours seems to lack them.

Oh, my bad. Thanks for the feedback again!  :blink:

Keep in mind Nabis pseudoferus may also occasionally lack the spots. I would put it as cf. ferus unless someone more familiar with ferus (I have never seen it, I only know hundreds of pseudoferus) confirms it beyond doubt.
