Planuncus tingitanus s.l.

Planuncus tingitanus s.l.

''Planuncus tingitanus s.l.'' is a working title for any of the species belonging to the ''Planuncus tingitanus'' species group, of the cockroach genus ''Planuncus'' . As the exact status of some the species in this group can not be determined without more research, the whole species complex is referred to by the name of the oldest species in the group sensu lato .

As such, ''Planuncus tingitanus s.l.'' refers to an adventive species, or possibly a complex of cryptic species, that has dramatically expanded its range over the southern parts of Northwestern Europe in a very short period of time during the first decades of the 21st century.
Planuncus tingitanus s.l. - teneral ootheca on female A fresh ootheca on a Planuncus tingitanus s.l. in the process of being produced. It will rotate 90 degrees when completed and she will carry it around like that for a short while until it has hardened and she has found a good place to drop it.

Habitat

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. Contrary to similar looking cockroaches such as the German cockroach they will however not likely procreate inside and as such need not be considered to be a household pest.
