-Zygiella x-notata-

UPDATE: 2020/02/18

Waarneming.nl admin Hans Nieuwenhuijsen, expert on Pompilidae, indicates that the wasp is not Auplopus carbonarius like I had determined but:

a female Agenioideus sericeus [1,2], with captured orb-web spider Zygiella x-notata (det. johanb).

This is a very rare wasp in the Netherlands that until recently only occured in Limburg [3], the most southern province, but may be expanding northwards according to Hans. This wasp has a preference for Zygiella x-notata. The observation and comment by Hans can be found here.

An awesome observation!! Only bummer is that I did not get the species correct the first time 😅. In hind site the differences between the species are clear.

A nice little wasp that I hadn’t seen before. She pulled the spider across the ground but unfortunately I did not see what she did with the spider as I was distracted by another insect that was my target at the time.
