Roachsmith Posted July 31, 2009 Share Posted July 31, 2009 Can someone please ID these roaches for me? I found them in Santa Rosa, California. They're small, about .25" and appear to be adults. I originally thought they were nymphs because of their size and they resemble german roach nymphs. However, one of them is laying an ooth! Hope someone knows what they are!

RosenKrieger Posted July 31, 2009 Share Posted July 31, 2009 You might have better luck with an ID over on the SCABIES forum. Someone's bound to have found these before. I know Andrew found some interesting desert roaches a few months back. Quote Link to comment Share on other sites More sharing options...
Allpet Roaches Posted July 31, 2009 Share Posted July 31, 2009 It's a recently introduced species (probably brought in with nursery plants) that's been around Marin County California for at least four years. Are you from there? Unfortunately, I don't think anyone has been able to identify it. Quote Link to comment Share on other sites More sharing options...
Roachsmith Posted July 31, 2009 Author Share Posted July 31, 2009 Interesting. I'm in Sonoma County which is pretty close to Marin. Do you have any suggestions of where I might send one (or a pic) for ID? I will try the SCABIES forum too. Thanks. Quote Link to comment Share on other sites More sharing options...

Allpet Roaches Posted August 1, 2009 Share Posted August 1, 2009 Roachsmith, your best bet is trying your local Agriculture extension agency though there's a good chance they'll have no answer. whats the scabies forum? anyone speakee english here It's a southern California arachnid group.

Kimix Posted August 2, 2009 Share Posted August 2, 2009 So I looked this roach up on bugguide.net out of curiosity And there's a few postings of it, along with a response from a guy from CDFA from '06 that they tried to have this roach ID'd, and couldn't. "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." Link to Above: http://bugguide.net/node/view/87476/bgimage That guys email is available if you click on his name, perhaps drop an email and see if he ever got an ID?

Allpet Roaches Posted August 2, 2009 Share Posted August 2, 2009 There are short winged species like Blattella lituricolis but it's too small and the cerci are wrong. Did you happen to find/see an adult male? Quote Link to comment Share on other sites More sharing options...
Roachsmith Posted August 2, 2009 Author Share Posted August 2, 2009 I have never found any males, but there seems to be lots of females under bushes. I'm wondering if maybe males hang out in the bush instead of under it. I'll have to take a better look next week. I did get a reply from someone at the California Academy of Sciences: "The cockroach that you are seeing was first noticed in Marin County a few years ago. Specimens were sent to the California Department of Food and Agriculture, and they in turn sent the specimens to a specialist in Germany. So far, we have not heard back from them. There are no specimens of this species in the CAS collection. It appears to be from a species group found in SE Asia. By the way, only females are wingless – males have wings." Norman D.

Ralph Posted August 3, 2009 Share Posted August 3, 2009 It's quite cute. Have they been seen to be pestiferous? Quote Link to comment Share on other sites More sharing options...
Roachsmith Posted August 3, 2009 Author Share Posted August 3, 2009 They don't seem to be. The majority of them prefer to be outside. Quote Link to comment Share on other sites More sharing options...
Roachsmith Posted August 10, 2009 Author Share Posted August 10, 2009 Someone at the British Museum has identified them as Phyllodromica (Luridiblatta) trivittata. I'm sending them some specimens for study Quote Link to comment Share on other sites More sharing options...

Roachsmith Posted August 11, 2009 Author Share Posted August 11, 2009 They're pretty hard to catch and I'm starting to find less of them. I'm working on getting more though so I'll let you know The roaches that hatch out of those ooths must be TINY! The ooth is only as big as a grain of sand!

Ralph Posted August 11, 2009 Share Posted August 11, 2009 How would one contain a roach that small? If they couldn't climb glass, it'd be easier. Quote Link to comment Share on other sites More sharing options...
Roachsmith Posted August 11, 2009 Author Share Posted August 11, 2009 Maybe! I will see how many I can collect this week Quote Link to comment Share on other sites More sharing options...
Roachsmith Posted August 11, 2009 Author Share Posted August 11, 2009 How would one contain a roach that small? If they couldn't climb glass, it'd be easier. I don't know. They can climb glass very well. Bug barrier might work, I haven't tried that yet. Quote Link to comment Share on other sites More sharing options...
Ralph Posted August 11, 2009 Share Posted August 11, 2009 Putting a couple nymphs in tic-tac boxes or little bug-magnifying cube things until they get to be managable sizes is worth a try. Or they could be like Parcoblatta where the nymphs can't climb but adults can. Quote Link to comment Share on other sites More sharing options...
Roachsmith Posted August 11, 2009 Author Share Posted August 11, 2009 I have them in a plastic cube right now with no air holes yet. If I find any nymphs or some hatch out I'll see if they can climb glass. Quote Link to comment Share on other sites More sharing options...
BugmanPrice Posted August 13, 2009 Share Posted August 13, 2009 How would one contain a roach that small? If they couldn't climb glass, it'd be easier. microscreen and copious amounts of petroleum jelly. Quote Link to comment Share on other sites More sharing options...
