But can you rule out 'our simple' Blatella germanica?
Comment by geechartier at 28 Feb 2020 11:10:08
@oleg_kosterin I cannot rule it out but I cannot be sure that it is that. I have posted several photos of roaches in this family to the Cockroach Species File Facebook group and, in most cases, am told that not even a genus ID is possible. Until I can find some information to help ID these from photos, I have given up trying!
Identification by william91803 at 28 Feb 2020 13:57:51
Taxon: Blattella [genus]

The abdominal structures and genitalia are usually required to identify Blattella species.

@william91803 could you kindly let us know if only Blatella germanica abounds in houses at high latitude or we are unaware of some species lumbed under this name?

@oleg_kosterin I'm not sure about the indoor Blattella species in high latitude in your region, but B. germanica does can thrive in the building in such area. Normally, only B. germanica abounds and can reproduce constantly in house. However, sometimes other outdoor species will enter and reproduce in buildings by accident as well, but they're usually not doing good as german roach is.
