Friend or foe? - Luridiblatta trivittata
San Anselmo, Marin County, California, USA
October 14, 2006
Size: 1-2cm
Started appearing over the last month. Thought they were baby roaches, but they are all the same size. I find them on the kitchen counter, and on the floor. Generally in the morning cleaning up in side and outside. Quick little guys. I have also found them under cardboard or dry leaves outside. Now that it got cold and wet they are gone. Oh they squish easily - I tried to pick one up. The picture is a macro shot after I got one in a wine glass.

Invating Napa, CA
We started seeing these after our trip to Monterrey. So far I have found three. One inside the durty clothes from our trip, one near the garage door and today in our patio table in the back yard. Grrr! These are descusting looking and can't imagine finding these inside my home next. We have small children, how can we get rid of these? Anyone? Please let me know!

Moved from Cockroaches.

Phyllodromica trivittata
The species is Phyllodromica trivittata. For more details see here.

Yes, these are definitely cockroaches - and they are adults - but they are not any of the typical house pest type - i.e., not the German roach or American roach, etc. We (at CDFA) were alerted of this cockroach over the last year or so, but can find no one who knows the species. We have sent specimens to numerous people to try to get an identification, but so far turning up a blank. I will be curious if anyone knows what it is in this forum.

They are certainly young roaches, and yes they do squish easily. They traded in their heavy armor for speed ;-)
