Dusky Cockroach - Ectobius lapponicus

Dusky Cockroach - Ectobius lapponicus

More likely Ectobius lapponicus ?!
Howdy,

To me this is a rather typical female Ectobius lapponicus. At least in Europe E. pallidus does not (ever) have the heavy dark/black spots on the elytra and in E. lapponicus these are standard issue.

Cheers, Arp

Tawny cockroaches
The size and coloration of this specimen are more consistent with E. pallidus rather than the larger, darker E. lapponicus. All three Ectobius species in the US are invasive, and so come with European common names. E. pallidus in Europe is called the Tawny Cockroach, but in the US is called the Spotted Mediterranean Cockroach (ESA-approved common name). Here, we had been referring to E. lapponicus as the Tawny cockroach, but I am not sure if this was a mistaken misapplication of the European common name for E. pallidus. In Europe, E. lapponicus is referred to as the Dusky Cockroach, which is much more appropriate for the darker color of this cockroach. There is no ESA-approved common name for this species as of yet. I’ve removed the listing of “Tawny Cockroach” from the preferred common name from E. lapponicus in hopes of avoiding confusion over this.

Moved from Ectobius lapponicus.
