  1. Would it not be easier to contact the enthusiasts from Japan? They have more or less everything and the distance is not too inconvenient for the animals... If you are allowed to import them, of course...?? BR/ Ole
  2. Could you tell from the dying roaches' behaviour that it was a poisoning of some sort? Or will your experiment of using a new bag have to reveil whether the food logically must be the source? As BugmanPrice suggests: Maybe the country of origin is of importance....
  3. Thanks for the answer. The diet will now change and at the same time, they will get a new aquarium. Last night they found a way out, but luckily the night temperature was somewhat low so only 3 of the biggest females got out and chose to hide nearby except one that went into the E.distanti tank - wonder what she expected to find there If you are buying dry food in 50 pound bags, your cultures are either big or really many....
  4. Hi Matt, Thanks for your answer. Is it intentional that you do not mention fruit? Or did you mean fruit and vegetables (like for the big hissers)? Orin was mentioning in his booklet, that E. chopardi is not as fond of fruit & vegetables as Gromphadorhina sp. So it might have been valid for all Elliptorhinas...
  5. Just got a small culture in Germany of this exiting and beautiful species. Are you caring for yours the same way as big brother Gromphadorhina?? I am asking because they do not seem to enjoy vegetables and fruit as much as the mixed dry dog food, that they were sold with. Are the nymphs red brownish and very different from the adults? Any advises about your experiences are very welcome Thanks in advance! If you are interested, I will upload photos.
  6. Hi Rafiqos, I have made some experiments, but I am not yet satisfied. Therefore I prefer to wait till it is better refined.
  7. Can you explain more about "commercial hedgehog food". Is that a special, high proteine mix - since hedgehogs enjoy meat? I am not sure that I can get it here. When you say "late-nite tv gadget" is that because you use same type of dried snacks that you would eat yourself (quite sweet)? Is your blend dry enough to keep mould away?
  8. When my E.distanti was only having egg cases, the nymphs were getting too little moist and the death rate was too high. As soon as they got a layer of hard wood leaves they could hide and the moist would last longer for the nymphs. Today I use decaying wood, soil and topped of with leaves. They love that, but they can only be studyed at night, of course
  9. My Gromphadorhina species enjoys leaves from dandelion quite a lot. You might consider to put a piece of cork up against the side for molting or for eggsack handling. What kind of gravel did you use for the water bowl? They look white or transparent...
  10. Oops, I do not hope you got the impression I was going to experiment with low moisture food and no water, because there were no such intention! They have been given juicy apples from the garden together with some beetle jelly - with interest. Just to clarify. I would like to try using a water dish. How should it be made? A small cup with a free surface should not be optimal for the nymphs (once they arrive)?
  11. Thanks for this advice. I will supply moisture! How do you make a water dish?? With a half Tampax?
  12. Some cockroach enthusiasts here in Denmark experimented with a barrier using voltage from a battery to keep the climbing roaches in. Because of the good contact they have with the surface the cockroaches would feel a low voltage when they stepped on two electrodes along the tank rim and withdraw. So I have decided to make the experiment with my hissers. However, there was no conclusion on what type of electrode material to use and how to fasten it. The distance between the electrodes was held down to 1-2 mm [0.04-0.08 inch] to ensure even the smallest nymphs to touch both plus and minus electrode. Did any of you use/experiment with such a system?? If so, could you please share some results.
  13. Thanks for the answers. I have now bought a 28 litres [7.4 gallon] aquarium that I am preparing for them. In the subforum "Enclosures and Barriers" is a question on barrier, please check... In the bottom I intend to use 2 inch of dried beech leaves even it might not be necessary (easy access, because there is a forest nearby my home ). And then some cork bark to climb closer to the light bulb if they feel cold (room temperature is 73.4-75.2 deg.F). I read an article from June, 2004 by Orin translated to Exotic Insects Magazine here in Denmark, the topic being the hissers, where I understand that moisture is not important, so it should not be necessary to spray the leaves/tank?
  14. May the Big Roach in the sky protect you all! Hope the presents had not eaten their way out of the wrapping! Merry Christmas.
  15. How much space would you recommend as minimum for 7 adult portentosa? Gender: 2 females and 5 males. I bought them in a big glas jar and there are some commotion (+ hissing) from time to time. Would you recommend a terrarium higher than wide because of their climbing abilities? I have a plastic tube (acryl) intended for a garden bassin for goldfish. Dia = 20 cm (8 in) and H = 50 cm (20 in). Would that leave too little floorspace (footprint)?? Merry Christmas to all Roaches and all roach lovers!!
  16. My Eublaberus posticus got some Mealworms as an experiment because they are really bad wingbiters and I read in Orins handbook "Allpet Roaches, Care and Identification Handbook for the Pet and Feeder Cockroaches" that posticus will eat newly molted almost any type insect alive. So my hope was that the posticus would add to their diet and spare each other a little around their own molt. But the plan did not work out. The posticus were still chasing one another and the Mealworms were very active living the good life in the tank. There was only eggcases and empty toilet rolls as shelter, but the Mealworms did not seem to be annoyed. After about a month I gave it up because it was not meant to be a culture. However, I intend to try again, but with the mini-Mealworms instead of the normal size ones - in the hope that the posticus will recognize a little "snack"... Did any of you try the mini-Mealworms?
  17. Thank you for the Welcome. Yes, your photos were published in april 2002 [No. 31] in an article about Mantispidae by Tom Larsen, EI's chairman. The captions said the species was unknown, but since you have the original photos and the article was in B&W at the time, you could check it up against either Leptomantispa pulchella (mainly western part of US) or Dicromantispa interrupta (which is larger and from northeast of US). Just a suggestion. Orin has delivered materials over the years and is very well known to the danish readers. Actually, articles from the magazine "Exotiske Insekter" was translated into english and published under the name "Invertebrate", starting in 2002, but unfortunately the interest was too little. A pity because also material from the german entomologists found its way into the pages - and they are quite enthusiastic as well! A personal question: Your name sounds strikingly danish - is that just a coincidence or ... ??
  18. Dear forum members, Greetings from Denmark by an amateur roach snoop trying to sneak into your ranks! After having started like most by using roaches as food mainly for the spiders, mainly tarantulas, it has been inavoidable not to fall for the many sides to the roaches. So now I am housing 8 species and before considering more you can expect to be looked over your shoulders and get a few questions from time to time.... I am a member of the danish association "Exotiske Insekter" [=exotic insects] with danish language forum on Exotiske Insekter, EI publishes 6 issues a year of our magazine EI-News - unfortunately in danish. Besides this I am a subscriber of Invertebrates Magazine. Lukily I-M has articles on roaches regularly... Looking forward to spending time on this exiting forum and you all! The best regards Ole Bjerggaard [OBJ]
