For same reasons than the previous species, this species belongs to the rhenanus species group. This species is commonly found in uncultivated areas and sometimes in crops in Europe, mainly on plants of the family Lamiaceae . However, no data on its biology were available until recently. Five populations of this species collected in South of France have been studied. Their abilities to eat Tetranychus urticae as well as their fecundity were assessed in lab experiments. Differences between the five populations have been observed. The fecundity rates (number of eggs/ female/ day) ranges between 0.5 and 1.4. The number of eggs T. of urticae consumed per female and per day ranges between 8 and 18. When the amount of prey is important in first days of the experiment, predation rates higher than 40 eggs consumed per female per day have been observed ( Tixier et al. 2016 ). The number of prey consumed for some of the populations herein tested is quite similar to those reported for some predatory mite species used in biological control, such as Neoseiulus californicus , for example. Such results emphasize the potential capacity of that species to regulate T. urticae . Furthermore, as this species is endemic of Europe, such results open new insights for using endemic biodiversity to limit side effects of biological control within international exchange rules. However, additional studies are clearly needed to determine optimal rearing conditions, prey ranges and predation behaviour in field conditions ( Tixier et al. 2016 ). This is the first mention of that species for the Slovenian fauna.
