Relationship with Welwitschia
They are best known for their association with the unusual plant Welwitschia mirabilis, also endemic to the area, but it is in doubt whether they actually serve a role in pollination or only drink Welwitschia sap.[3] In addition, they may spread a fungus, Aspergillus niger, in the process, which is harmful to developing seeds.
Comparison with Probergrothius sexpunctatus
The species has been recognized under a misattributed name, Probergrothius sexpunctatus, for several decades, but P. sexpunctatus is a separate species that occurs farther to the north.[4] P. angolensis is yellowish with four black markings on its wings, while P. sexpunctatus is more reddish, and the anterior spots are separate, so the wings have six black markings.
