Therefore, Bohn et al. (2013) prefer to identify the animals adventively spreading over Northwestern Europe, as well as the North African specimen (other than the types) as "belonging to the tingitanus-complex".

Now, Bohn et al. were prompted to publish the (preliminary) results of their studies "as is", without conclusive (molecular) evidence for the status of the species concerned.

Quite similar to Ectobius vittiventris, another species of Ectobiinae rapidly moving north in Europe, the animals seem to be more or less dependent on human activity, both for their range expansion and for survival.

Being of southern origin, it is not surprising that they seem to thrive best in the relatively warm and sheltered environments provided by buildings and parks or gardens in towns.

In this respect they will live much closer to humans than what would be normal for the native species of Ectobiinae and can readily be found on the walls of buildings and may even stray inside.
