Neoseiulella aceri was the second most common species on walnut in Czech Republic and the co-occurrence this species and E. finlandicus was often observed (Kabicek 2010).

Despite these observations, the biology of this type III species (McMurtry et al. 2013) is almost totally unknown. This species is mostly reported on Acer species (Kanouth et al. 2012)

This is the first mention of that species for the Slovenian fauna.
