    Goodbye for now...

    Sorry to hear this, HIsserdude - you've been one of the most helpful and knowledgeable members of this forum and certainly helped me with a few problems I had with my colonies when I started keeping roaches. I hope all goes well and that with a new balance to your life, as Krissim Klaw said, you don't completely lose your obvious love for these little creatures. I can certainly sympathise with the time commitment - having started off with just three hissers about 18 months ago I now have thriving colonies of 6 stick insect species and 3 hisser species, all of which are reproducing like mad and eating me out of house and home as well as taking a lot of my time! All the best and hope to see you here back again some day with a new enthusiasm!
  2. Well they certainly seem to be breeding well for me at higher temps so I would suggest you try a heat mat to get the temperature up a bit. I am surprised they are dying off at those temps though - I would have thought they would survive but just not breed or grow very fast?
  3. It varies around the enclosure - probably about 26-28 Celsius near the heat mats (I have two smallish ones, one under about a third of the cage and one on the side in the same area) to about 18 Celsius on the other side away from the heat source, so they have a choice of warmer or cooler areas. Not sure what those are in Fahrenheit - maybe 65 on the cool side to 78-80 in the warm area? I do find they tend to congregate nearer the warm areas but not so obviously that i should increase the temps all through the cage. Both heat mats are on thermostats set at 26 and 30 Celsius so they are on most of the time in the winter but off most of the time in the summer. Hope this helps!
  4. LOL I’ve had the opposite experience with E. javanica - they breed like rabbits for me! I started off with 7 females and 11 males in May last year and now have so many tiny babies (literally hundreds) I don’t know what to do with them - and that’s after giving away probably over 100 mostly adults and large nymphs a couple of months ago! what are you feeding your javanica? Are you giving them any other fruit and veg in addition to the roach chow and carrots? It may be that you need to give them more varied fruit and veg to thrive - mine get lettuce (which they love), carrot, broccoli, banana, apple, orange and pear on a regular basis plus dry cat treats and porridge oats for protein; they are kept on a dry coir substrate with a heat mat under which gets sprayed three times a day for 10 seconds by an automatic misting system. They also have plenty of cork bark and artificial plants to hide in although there are so many now that they can’t fit in all the spaces - I am probably going to have to split the colony soon! However I have also found oblongonota to be slower going than javanica - my first experiences with them were not great and although I now have a thriving colony with lots of nymphs (kept exactly the same way as the javanica) I have found they breed slowly and the females seem to suffer a high rate of prolapse on giving birth which usually means the female dies (though not always), but it does lead to a lower birth rate as a result. I've also got a G. portentosa colony which started off as a group of 2 males and 2 females but is rapidly going the same way as the javanica! Again kept the same way. I would suggest trying a wider variety of fruit and veg and seeing if it helps?

    Roach Etymology - Help Please!

    I’m not an expert in Ancient Greek by any means but I do know the ‘planeta’ part of Periplaneta comes from the Greek for ‘wamderer’ or ‘to wander’ as this is exactly what the ancient Greeks called the planets, because the ancient astronomers noticed that the planets ‘wandered around’ the sky in relation to the other stars which always had a fixed relationship to one another. So you’re correct in one sense because the word planet has the same derivation, but Periplaneta strictly means ‘wandering around’ - which is also very appropriate for the species as it is often seen wandering around everywhere!! i have a smattering of Latin from my school years so I can sometimes work out what some Latin derived names mean but other than the tale above Greek is, well, all Greek to me , so I can’t help you with any of the others I’m afraid!

    Madagascan Hisser tried to lay an ootheca?

    Yes this is completely normal - female hissers often push the ootheca out and retract it again, I think both when first making it and also at least once (not sure how many times) during the incubation. I've seen several of my female hissers (of several species - G. oblongonota, G. portentosa and E. javanica) doing this and it's perfectly normal. If she has just made the ootheca it will probably be several months before she has the babies, but if it's one of those cases where they push out and retract the ootheca part way through incubation you may not have to wait so long.

    Compsodes schwarzi (Schwarz's Hooded Cockroach)

    Are the ones in the most recent photos the same ones / same generation as the hatchlings from a few photos above? or are they a later generation?

    Jet black Gromphadorhina portentosa?

    Here is one of my "black morph" portentosa - a female, I think adult but may be subadult. There is no trace of any other colour than black anywhere on her body. Isn't she stunning?
  9. Hmm, interesting - I recently increased the humidity in their cage so I wonder if this has had an effect? I am using an automatic misting system which was misting too much in the summer and causing mould, so I reduced the timings, but then it got a bit too dry, so I increased the timings again about a month ago and also sometimes spray by hand if I happened to be feeding them. I have definitely noticed it is more humid in there when I open the cage door, although the substrate is still completely dry. I wonder if this is what has induced all the females to give birth?
  10. LOL and this morning I woke up to find a whole load of tiny white newborn baby roaches in one corner of the tank as well - so they are definitely producing now!! Interestingly almost all the adults in my colony were born at about the same time as this last year. I wonder whether hissers have any sort of seasonal birth timing preference or whether it’s just a coincidence?
  11. Just wondering whether it was possible to get a "jet black" morph of Gromphadorhina portentosa as I have got a couple in my (growing) colony. They are completely black all over with no sign of any lighter colouring, stripes or patterning anywhere on the body. I have a colony of about 50 adults and subadults overall which all came from two litters from just two founder females, and the vast majority of them are the "normal" colouring for a G. portentosa i.e. tan/brick coloured abdomen with darker pronotum and thorax - some show a graduated darkening from abdomen to thorax, but others have some darker striping or patterning on the abdomen and thorax as well, but these completely black ones stand out quite a bit. They were sold to me as G. portentosa though there was no specific indication that they are "pure" stock, I am guessing they are hybrids of some sort but does anyone know whether there is genuinely a "black" pure G. portentosa colour morph, or are these ones more likely to be a throwback to some other species they were crossed with in the past?
  12. Just to follow up, there have been at least two more births in the last week so I now have loads of teeny little ones running around in the cage! The first batch have now moulted at least once (most of them twice) and are looking enormous in comparison. So it looks like they were just taking their own sweet time to give birth - and now they have started I'll probably be knee deep in tiny roaches before long

    Long molt and help needed

    Unfortunately you probably couldn’t do anything to help her, though I completely understand how you feel - I have felt this way too with some of mine that have died with bad moults, but having kept insects (roaches and also stick insects/walkingsticks) for about 18 months now I have come to realise that some of them simply do have bad moults, prolapses during birth or are just sickly individuals for no apparent reason. and there really is nothing I caould have done about it. Yes on some occasions I’ve messed up and have learned from that experience but now I have more experience of keeping insects I just put this sort of thing down to nature doing its thing and ensuring only the fittest survive. Still doesn’t make it easy to lose one though
  14. They definitely do get to around 5.5-6cm, I thought that was the normal size for javanica though - I haven't seen any (at shows etc. not just in my colony) where the maximum size is much smaller. Perhaps European stock of javanica is bigger than US stock? Could that be possible? Mine are also very well fed - I always make sure there is food in with them at all times and never end up with periods (even a day or two) when they have none at all, so maybe they have grown bigger because they had more nutrition as nymphs? To be fair there are smaller individuals in the colony as well (some adults are only 4cm for example) but significant adult size variation seems to be the case for all hisser species I have. Some of my oblongonota males for example aren't any bigger than the female javanica pictured, but I thought that was just because they were "minor" males and it was normal to have both large and small individuals in all colonies? Is that unusual?
  15. I've just been measuring my roaches and my javanica definitely grow to about 5.5-6cm, a big male or female can get quite large. However they are nowhere near as big as say a Gromphadorhina oblongonota - some of my biggest oblongonota males are over 8cm and they are built like tanks too! However oblongonota aren't that variable - they do have variations in the markings on their backs but these are not obvious from a distance, so probably would not fit your criteria. For what it's worth I've attached a photo of a large female trying to climb the glass of her cage next to a tape measure showing she's at least 5.5cm long, and a photo of a group with a few red-pronotum individuals (two females at the bottom and right of the group) with some black pronotum and nymphs. Neither photo is particularly good I'm afraid - I was trying to hold my phone and a torch to light them and take a photo at the same time before they all scuttled off under the cork bark and fake plants! It might be worth considering hybrid Gromphadorhina portentosa if you are not bothered about whether they are a pure strain - mine (I am guessing they are hybrid) are very variable in both the base colour, and the amount of black markings on the abdomen and pronotum, and they definitely get bigger than the javanica.
