  1. the squarres on the paper are 0,5cm long, so they're about 5cm
  2. Hi! Here are my Elliptorhina javanica: a male: a female: a young one: Bye!
  3. Hi! I've noticed various colours in my Byrsotria fumigata colony, is it normal? black female reddish one even more red (sorry for the quality, but can't stop her to move...): here you can compare the colours: brachyptera male (classic form): macroptera male (less common form): bye!
  4. hi here are some of my Blaptica dubia female: male: some babies: bye!
  5. the squares on the ficture are 0,5cm large The roaches are about 6-7cm and don't climb smooth surfaces, I always see some of them on the floor or on the egg crates, this specie is easy to see
  6. hi here are some of my Archimandrita tessellata: un baby: it will grow up... some classical peppered colour two darker ones: bye!
  7. very nice species... Most of them aren't in the european hobby, that's amazing to see them!
  8. Hi! Here are some pics of my roaches... Aeluropoda insignis, colony from a breeder quiet red female: male some babies and... bonus! Aeluropoda insignis, from importation (Madagascar - unknow local): males: one is more red, the other is darker: quiet red female: a darker one: some babies... bye!
  9. hi they LOOK like Gromphadorhina oblongonata, but I'm not sure they are. The only way to know their exact specie is to let a specialist look at the male pronotum... As wodesorel said, a same specie can show loads of diferent colours!
  10. I mean they will inbreed with the local populations and pollute them
  11. release insectes you breed in the nature, probably the worst thing to do... There are often diferent locals, and many roaches in captivity have been hybridized... just polluting the savage populations...
  12. first birth last week, in my wild caught colony and in my "normal" colony!
  13. hi when a female has given birth, normally, every babies get out at the same time, there won't be any more birth from this clutch. Hard to say if the deformed baby will survive, I noticed they often die after a fex days.
  14. welcome! There is often competition when you keep different species together... it's better to keep them separated
  15. for the food, antennae can detect "odors", but not at the sense we would understand if I remember it well. They detect there is something new, potentially food. When it is considered as a potential food, they go near it and still use the antennae to find it. The use the palpae when they are really close to it, they firstly touch the stuff with their palpae and they identify wht is it (food, soil, well, anything!), and when it is considered as a possible food, they start eating it with their mandibles. While eating, you've probably noticed that roaches often use their first pair of legs to maintain the food in place or taking it away. And if you look closely, you'll see what happen near their mouth: they chew little part of food to get pieces small enough to swallow with the mandibles, and the palpae are used to keep what their are chewing near the mandibles. So antennae are mainly used to detect smells and things moving around them (they detect pheromones, give a first information about the presence of a potential source of food, they detect other roaches, predators and so on), while palpae are used to identify what they touch, the soil composition and to really taste and identify food
  16. science class, entomology class (university and evening classes) and every serious book dealing with insects Antennae are not the only sensory organ. They have many function as I said, they can detect the food, but not taste it. Palpae have more precision, they can tastethe food, identify the soil, his moisture, composition and so on... Those organs are essential to find the food, when antennae are not (but they have loads of other functions that are highly useful )
  17. antennae are definitely used to sense changes in the environement: vibration in the air, phoromones and so on. It give very little informations about food: when you add fruits or something, they sense something has change: moisture, maybe an odor... nothing more. Look at a roach, or at any insect, near his food. The antennae are moving, but it doesn't it the part of food he touch with the antennae: he taste his food with the palpae... that's their function
  18. hi Polyzosteria are cockroaches yes, but I've never heard anyone breeding them :/ I'm currently starting a colony of Gyna caffrorum, I hope to have some of them available at the end of the year
  19. very nice looking roaches! If you're interested in an exchange one day, i'd be interested
