    Aww man . . . what a ridiculous oversight!  I've been keeping bugs for over 20 years . . . just goes to show that even us 'old timers' can make a super rookie mistake!  

    Thank you for pointing that out . . . yes, I've been meaning to type Porcellio hoffmannseggi this whole time . . . 

    Guess that brings me back to my original question . . . Any good care info or links for Porcellio hoffmannseggi?  

    Mine do well in an 18 qt. container with good ventilation. Things are basically bone dry except for one corner of the enclosure that I keep a moist clump of sphagnum moss in. Besides that, they have a couple, large pieces of bark for hiding under. Their diet consists of dog food and carrot.

    I've been battling some phorid flies lately. I'm very confused why I keep finding dead adults in my b fusca and Peruvian bins. I have tons of nymphs and the living ones seem to be thriving, but I'll find a few adults dead swarming with flies pretty regularly. Don't seem to be finding any dead nymphs though. Are the flies attacking the roaches or do you think these roaches are just dying from old age? Everything seems in order 80ish temps, moist substrate with dry areas, ventilation, hiding, etc. I have 30 some colonies and I rarely find them anywhere else.

    If you could leave out a freshly-perished individual in a location where it is easily observed and see if the flies mess with it, that should make the lifestyle of your Phorid Flies clear as day I'm thinking. :) I would assume that the roaches are simply dying from old age though.

    Huh!  That's the first I've heard about them needing rotten wood.  Very interesting.  

    I've also read that they need a very dry setup with just a corner that's moist, and a lot of ventilation.  Seem about right?

    Indeed! Based on how few species require it, I would have never suspected that facet of their husbandry myself. lol Glad someone else did, though!

    For the rest, what @Cariblatta lutea said. lol

    I'd like some solid care info on Platyarthrus hoffmannseggi.  

    Is there a good link?  Or, please tell how you keep yours.  :)

    As @Arthroverts mentioned, me and @Cariblatta lutea are both keeping this species. I'm just starting out with mine, but from what Alan (C. lutea) tells me, the need for rotten wood is the only really unique part of their care from most other isopods in the hobby. He has been successfully culturing his for over a year now I believe.

    No, apparently not that. Beetles are daytime, and cockroaches are nocturnal; they just don't need such protection. In addition, this happens only in males, females are always clean and shiny. I assume that this is due precisely to the libido of males. There is an assumption that this substance has an attractive smell for females. It would be very good to examine the chemical composition of this substance, as well as the abdominal pleura for any glands there. Only who would do this? :D

    Or maybe it was simply thought of as a desiccation buffer, I forget. Either way, the other theories mentioned here are much more valid. 

    Exactly. LOL People can't even manage to figure out their taxonomy, let alone the even finer nuances of their beings. 😂

    Hello dear like-minded people!

    I am very glad that there are so many of us — Blattodea lovers around the world. Thank you very much to the forum administration for hosting me here!

    I have been doing Blattodea for over 20 years. His main interests are the tribe Gromphadorhini, the family Corydiidae, and the subfamily Panesthiinae. In general, I love everyone Blattodea sensu lato :rolleyes:

    Welcome! Awesome to have you here. 🙂

    I'm currently breeding 4 species of roach, and as the title suggests, would like to know whether adding unrelated bloodlines is necessary for a healthy colony. I've heard many different things from many different people and would like to hear from some veteran breeders on the issue. Thank you in advance for any help!

    I would say in the vast majority of cases, absolutely not. Really the only species in the hobby that's *thought* to possibly have issues stemming from that is Elliptorhina davidi (since the captive stock originally comes from a single gravid female), which have continued to flounder in captivity years after being introduced to it, but we also might just not understand some aspect of their husbandry. Almost all of the other species stocks in the hobby come from a handful of individuals imported multiple decades ago without any new bloodlines introduced since then, yet they still thrive to this day. 

    As for first hand experience, I have some colonies that have been going self-sustained for nearly half a decade now and I'm not seeing any signs of any sort of weakening.

    Hello all, so recently I was nosing about under some pots (like I usually do), and I found this:



    Apologies for the poor quality, it was completely dark when I took the photos and the camera didn't have enough time to focus once the flash went off.

    Anyway, just your regular Blatta lateralis. Pretty, but not very exciting. But that got me thinking. What species would you most like to find under a pot/log/stone? Say you are on a trip to somewhere, you flip over a log and bam! What species would you like to see? For me it'd be Blaberus/Eublaberus sp., or possibly some cool Panchlora sp.



    Probably some odd, large Corydiid or Eurycotis pluto. 🙂

    How do colony collapses happen? I run into that term a lot while reading the forums. Thanks!

    Usually they overpopulate, aren't tended to properly (lapses in feeding, watering, or temperature), catch an entomopathogenic fungus, or two species are kept together and one outcompetes the other,
