Habitat preference: Allochernes wideri is associated with dead wood, especially with oak, and can be found under tree bark or in the decaying wood (Legg & Jones 1988). In Slovakia it has been reported from bird nests (Christophoryová 2011d; Christophoryová et al. 2017b), from ant nests (Červená et al. 2020b; Christophoryová et al. 2017b), from mammal nests, from the combined nests of birds and mammals (Christophoryová et al. 2017b), from heaps of decomposing plant material (Kaňuchová et al. 2015), from compost heaps (Christophoryová et al. 2017a), from dead wood and from tree hollows (Christophoryová et al. 2017c). It has also been reported from under dead wood bark in Lithuania (Krajčovičová et al. 2018). In Hungary, it has been reported from a pasture with trees (Kárpáthegyi 2007), and in willow forest (Novák 2013a). During the present study, it was found in artificial bird nesting holes, in maple forests, in loess steppes, and in lakeside (microhabitat not specified).

Remarks: this species was first recorded from Hungary Kárpáthegyi (2007).A second occurrence was published by Novák (2013a).
