    Another Archimandrita tesselata male hissing

    Today I managed to capture a video of another of my Archimandrita males hissing when disturbed.  Anyone else with hissing Archimandrita roaches?

    DIY Modified Sterilite Gasket Tubs from Target

    Very nice and good explanation!  Quite similar to what I do, albeit that yours look definitely better.  I recognize the 'broken plastic' issue. I did not dare to return to the shop... Buying a sealed container to have a hole punched in :)   I use stainless steel frying pan splatter guard as...

    Agar blocks with banana aroma as water source

    Does anyone else use agar gel instead of water crystals to water their roaches?  This is what I do: I make a 1% agar gel. I mix the agar with water and boil it. Next I poor it into a plastic box and let it cool. After that I cut it in small blocks and put them in a container with water.  To...

    Polyphaga saussurei elevated activity

    I have 7 Polyphaga saussurei roaches since november 2016. It looks like some are now becoming adults.  And while so far they almost never got to the surface, even at night, one adult female saussurei is above ground every night since a couple of days.  At first I was wondering that she might...

    Eupolyphaga sinensis: first babies (photos)

    My first Eupolyphaga sinensis nymphs appeared!  I managed to get some photographs of the 2 day old nymphs. They must have eaten already, as their intestines got dark. They are about 3mm / 0.12 inch in length.  The ootheca hatched after about 6-7 weeks (at constant 28C / 83F).

    Cockroaches on their back, flipping (and digging)

    Out of curiosity to see how different cockroach species handle being on their back on sand, I made some videos.  Fine sand is very difficult for insects deal with...  First: Eupolyphaga sinensis female:

    Advice on Polyphaga saussurei?

    I don't know the optimal breeding temperature. Although I think room temperature would do fine.  I can't immediately find the article I've reads about the life cycle of Polyphaga species in the region where one can find Polyphaga saussurei. I remember it to be a life cycle of hibernating in...

    Archimandrita tesselata Hissing

    I discovered that older male Archimandrita tesselata roaches can hiss. I was completely surprised that when I touched one of my 2 year old males, he hissed. Pretty much the same way as a Madagascar roach does (albeit much fainter). I checked to see if it wasn't through wings scrubbing or...

    Computer regulated enclosures

    Perhaps it would indeed be a good idea to put it all on my website.It's relative low cost, as it's mostly off-the-shelf material. I'll try to organize and document it all.  What took most of the time was building the software to do the motion detection, create decent PID temperature controllers...

    Computer regulated enclosures

    Maybe I should document it all on a blog or something. That would allow me to share code and designs (which a gladly would like to share).  It's fun to see their activity in real-time. I have to admit that I tend to 'check in' on my roach bins while I'm at work (and the boss isn't looking :)...

    Computer regulated enclosures

    The P. saussurei indeed a crepuscular activity pattern. They are often inactive in the middle of the night. The animals in the enclosure are adults.  The P. obscura roaches are much younger nymphs. And they are active the whole night.  The Therea roaches (also nymphs) show a much longer...

    Computer regulated enclosures

    Recentlly I automated my cockroach enclosures.  An automated day/night heatingcycle. Gradual light dimming with red lights at night. Automated fogging to add moisture. This all combined with cameras that register and quantify movement.  That gives me quite a good insight on the activity of...

    50th Post!: Tinley Park NARBC Expo

    I've good news regarding this issue: There is a Chinese article that describes how one can distinguish P. obscura from P. saussurei.  "Study on the morphology and internal structures of Polyphaga obscura Chopart" (http://europepmc.org/abstract/CBA/297263) I've manages to get the complete...
