Friendly Cockroach

Luridiblatta trivittata


Spotted these tiny Friendly Cockroaches hiking the Ferry Point Loop Trail in Point Richmond, CA. They were about 5mm long, had long antennae. They are native to the Mediterranean, adventive in our area (CA, recently introduced), now apparently in Marin, Petaluma and Cotati. (

You're welcome. I happened to be researching cockroaches recently so I knew what it was :)

Thank you Cindy for the ID and thank you oxyjack for realizing it was a cockroach!

It was really tiny and moving fast, so those were the best photos I could get. It definitely had more than six legs. I'll try to see if I can crop the photos that I have to get a better photo.

It certainly looks like one, but it looks like a tropical species. I'm not familiar with any living in North America with that appearance. If I could see one close up, I'd be able to say for sure. When you say "it had lots of legs" do you mean more than six? If so, it wasn't a roach because it wasn't an insect.

Is it a cockroach oxyjack? And yes, it was spotted in Point Richmond.

That's one heck of a pretty cockroach! Was this spotted in Richmond?
