Roachsmith Posted August 8, 2007 Share Posted August 8, 2007 I've read some mentions of aquatic and semi aquatic roaches on different websites, but I can't find the species name. I'm really curious to learn more about them. Does anyone know what species they are? Quote Link to comment Share on other sites More sharing options...
Allpet Roaches Posted August 10, 2007 Share Posted August 10, 2007 I read something lately claiming Opisthoplatia orientalis are semi-aquatic in the wild though I can't recall exactly where I saw it. In the past I've seen some 'aquatic' species but they don't look different from normal roaches, nor are the requirements different. Quote Link to comment Share on other sites More sharing options...
Fredrik Posted August 10, 2007 Share Posted August 10, 2007 Orin, if you ever find it, please don't forget to post it on the forum as I'm very interested to find out more about them in the wild. Best wishes Fredrik Quote Link to comment Share on other sites More sharing options...
Megaloblatta Posted August 10, 2007 Share Posted August 10, 2007 There are dozens (if not hundreds) of species of aquatic roaches, all of which belong to the Blaberidae subfamily Epilamprinae. They are found throughout the tropics in rainforest habitats and I have personally collected them in Ecuador (from water-filled bromeliads), and in Papua New Guinea, Madagascar and Malaysia (under stones beside forest streams). Some species are more aquatic than others e.g. Epilampra abdomennigrum from Costa Rica actively swims and dives below the surface of water, whilst Stictolampra trilineata from Papua New Guinea climbs over submerged rocks (probably because it lives in fast flowing streams and would be swept away if it tried to swim). For more information about aquatic roaches see the excellent recently published book on cockroaches by Bell, Roth & Nalepa (http://www.amazon.com/Cockroaches-Ecology-Behavior-Natural-History/dp/0801886163).

Best wishes Fredrik Hi Fredrik, I can't remember where I read it. It was a report on the species in the wild, not a caresheet. A little experiment in a 40 gallon and they are able to surface after being submerged and can stay afloat at least two hours and the water doesn't see ot harm them at all. That's better than other semi-aquatics I've seen. Aquatic insects like waterscorpions would drown in that amount of time without a place to perch. Although there are a number of species associated with aqutic environments I dont believe there are any with oar-shaped legs or really noticeable external differences.

Ah ok. That's what I was imagining an aquatic roach to look like. Now I understand that they're just sort of resistant to water. There are quite a few bugs that can survive for some time submerged. I used to go around the pool at my grandparents house when I was little and fish out all the isopods on the bottom and most of them were still alive.

crittergu Posted August 16, 2007 Share Posted August 16, 2007 Are any aquatic roaches available in the US? IME in a viv isopods drown very easily. Some survive and manage to climb up the glass, only to drown in the film of water on the glass. Also, does anyone know if Lethocercus grandis is available live in the US? I hear they are sold in Chinatowns as food but have never seen them. Quote Link to comment Share on other sites More sharing options...
Allpet Roaches Posted August 17, 2007 Share Posted August 17, 2007 Opisthoplatia orientalis are available. Also, you can get waterscorpions from bugsincyberspace.com Quote Link to comment Share on other sites More sharing options...
Keith Posted September 15, 2007 Share Posted September 15, 2007 The American Cockroach I would say is semi-aquatic being it can swim so well and mostly living in sewers you get ALOT of water constantly. Even if another roach could live in a sewer and stay out of the water, the large amount of moisture would kill them not to mention the ever changing temperature.

Keith Posted September 17, 2007 Share Posted September 17, 2007 If you live by me there isnt many, but yes somewhere else in the world they may be lots of them. I only know of the American Roach here who thrive by areas with alot of water. Quote Link to comment Share on other sites More sharing options...

Keith Posted September 19, 2007 Share Posted September 19, 2007 Exactly I dont live in Taiwan, so I never saw that type of roach before. But thats a cool picture! Quote Link to comment Share on other sites More sharing options...
Allpet Roaches Posted September 20, 2007 Share Posted September 20, 2007 unknown sp from Taiwan That's a great photo. Is that species often found under water in real life or under specific conditions? Is that an adult female? I thought there weren't any unidentified roaches in Taiwan Quote Link to comment Share on other sites More sharing options...
Matt K Posted October 5, 2007 Share Posted October 5, 2007 While I was in Costa Rica, I found this roach to be pretty common in (extra) wet areas and in running water. If it were feeding on something above or near the water, it would run to the water or just dive in and go under some rock or other available crevice. I even found some underneath a submerged piece of wood. If they get into water they can move very fast. Quote Link to comment Share on other sites More sharing options...

I had the pleasure of owning a small colony of these briefly, but it nevertook root. entertaining little fellas, had to keep them in a semi aquatic state.. i forget exactly how i kept them its been so long but they were good swimmers.

Chun Xing Wong Posted July 19, 2014 Share Posted July 19, 2014 I photographed this semi-aquatic cockroach nymph in a river in Tawau Hills Park, Tawau, Sabah, Borneo (Malaysia). They are usually seen scavenging on river banks in disturbed forest here. Anybody got any idea on it's ID? Thanks. Quote Link to comment Share on other sites More sharing options...
