    Can anyone tell me what this is?

    Any pictures of the fusca hybrid - as adult? BR/ Ole

    Blaberus fusca

    How long are they? They seem to be a fairly good size. BR/Ole

    Roaches and Ants

    I have tried feeding E. posticus all sorts of insects, from fully alive to halfdead and dead, but nothing worked. But they prefer the high proteine fish flakes and they eat the dried sikworms that is also rich on proteines. ---- About the ant question, then they will not eat the ants, but some species live in a sort of mutualism. Some ants will bite off the antennas of certain roaches and keep them in the ant nest. The roaches get confused and loose orientation. So they wander around like cattle and is kept alive as long as the ants wants it... Certain Diptera (Conopidae) follow raiding army ants and paralyze cockroaches and lay eggs in them. Quite specialized. Some roaches live with the fungus growing ants where they live from licking secretions in connection with the chewing of the leaves. The common fact is that such species are adopted to their specialized behaviour over many many generations. However, to experience such mutualism in ones own hobby setup would be more than a challenge... unfortunately. BR/ Ole

    Baby Food?

    In several European languages compote is just a general term for stewed fruits. But since baby food is quite expensive - could be because it is a functional food - it would be much better to prepare one's own dish - including fruits. Actually I am using the oldest fruit with the brown spots because for some reason at least for some species they start with the brown spots before the fresher parts. Could that be because of their quite different bacterial composition or because of smell ?? BR/ Ole
  5. So you found the australean roach south in US, but how far north has it spread? To all states except Alaska, perhaps? BR/ Ole
  6. 5 month is a long time. However, I have noticed that if I change the complete layer of frass in the old bin with a new, fresh mixture, then the culture will start up slowly and if I look carefully fever nympth survive in the first time till it gets going again. My theory is that the nympth are eating the feces (think it is called coprophagia) to get started in their gut and then be efficient on all the different food that we all experiment with... So unless the culture is full of buffalo worms or similar, I have been adding at least 1/4 of the old material to the new. Have you similar observations or it could be more species-related with individual behaviour? BR/ Ole
  7. Thanks Bugman. That could solve it if I am lucky. Zephyr, just to see if it was possible to find something inside Venezuela, I have sent a mail to the so called "principal contact" of ENTOMOTROPICA "Sociedad Venezolana de EntomologĂ­a", a magazine there and asking them to point the right direction. Let's see what happens ... BR/ Ole
  8. HeHe, yes, a pitty I get there too little.... But that Hugo Chávez fellow gives me the creeps.... and he is calling USA names... BR/ Ole
  9. Thanks Bugman, Glad that you agree on the logic. Sorry that Venezuela was not amongst your references... Good joke about our plane-posticus... I can't help feeling reluctant to declare Venezuela as posticus-territory. Where else could such information be kept? BR/Ole

    Ant Attack!

    Here we normally lay out borax on the ant trail considering that it is not somewhere close to human paths so that it blows away. When the ants tread on it they try to lick it off and gets it in their stomachs. As the ant attack weakens, we usually vacuum all the ants and the remaining powder. But there are probably hundreds of advices and any pharmacist might advice you differently... BR/ Ole
  11. Are any of you roach-enthusiasts having secure source information about the distribution of E. posticus?? When checking out 'The Catalogue of Life', the registrated places were shown as: Nicaragua; Costa Rica; Panama; Colombia; Trinidad and Tobago, Republic of (Trinidad); Guyana; Suriname; French Guiana; Brazil; Peru; Ecuador. If you plot these onto a map, it becomes evident that Venezuela is surrounded by countries having posticus registered - like an island in the middle of a sea of posticus.... Any registrations, private or organization, about Venezuela?? Should they not be found there as well?? BR/Ole

    GEEZ roaches can EAT!!!!!

    That must have spooked a lot of spectators ... considering the way many deal with large insects and arachnids... How is it possible to get one's roaches on the screen?? Did any of them die during the take? BR/ Ole

    GEEZ roaches can EAT!!!!!

    Well, you probably should not bring any pics... It must have been quite a sight. Do you remember which species was that tolerant towards one another? BR/ Ole

    GEEZ roaches can EAT!!!!!

    Roachman, Do you mean that you kept them too hungry or that the overcrowdedness was too high? BR/ Ole

    Gromphadorhina oblongonota

    Interesting mutation from natures side... Does he move in odd ways - or is it not even possible to tell when he walks? BR/ Ole
