Note sugli ospiti

Habitat conosciuto

Habitat  
Piante per posa/rifugio Inula viscosa Ait. and Lavatera arborea L. infested by aphids, leaves of Ceratonia siliqua L., flowers of Euphorbia cyparissias L., Rubus (Invrea, 1922), flowers of Euphorbia (Schmidt, 1977)
Parassiti noti  
Note biologiche Because Pseudomalus females have never been observed at the nest entrances of their hosts, the suggestion is that Pseudomalus species place their eggs on the body of aphids before they are collected by Pemphredoninae (Veenendaal, 2011)
