  1. Ah, now I understand! Well, I myself do at times worry that I might not be able to distinguish my Polyphaga species if I ever had to. So in that sense I understand your hypothetical challenge

    Hey From NY!

    Welcome Cole! I'm pretty sure that your experience with all kind of invertebrates can help the roach community as well.
  3. I beg you pardon, but why do you need to be able to distinguish nymphs? Do you have them mixed? Or has the label fallen off? I'm a bit puzzled... But to be fair, I cannot directly help you with your question, as I do not have multiple hisser species. Although I find it very hard, next to impossible, to tell apart the nymphs of certain other related species.

    Ideas on how to collect P. americana from my school

    Build a trap?

    will take unwanted roaches

    I pity that you live that far away (Belgium - Ohio is about 6527 km / 4056 miles). Otherwise you could get some excess roaches.

    Blaberus gigantas not breeding?

    I think you should exercise some more patience. Could be that: - The adults aren't ready yet to reproduce. - The adults are very old. - It takes at least two month for the eggs to be ready. So... - Lower temperatures will result in longer hatching times. - Etc... None the less, I'm often impatient myself when I have new roaches. And patience one must have with some species... Good luck with your roaches! Link to: Useful information about this species

    will take unwanted roaches

    Perhaphs you can make an account and give some more information about things like: why, how, where.... That would certainly make communication easier and increase your changes of actually getting in touch. Just my 2 cents.
  8. A few days ago two of my Schizopilia fissicollis nymphes died unexpectantly. One just sat on top of a leave, the other on top of a piece of wood. Not moving.... Which made me suspicious. I have their death on camera (time-lapse). They have been moving around in the hours prior to they demise. Eating, walking, and then slowed down, stopped walking and after a few hours stopped moving altogether. So that made me consider that the condition in their enclosure wasn't, lets say 'optimal' I assumed they preferred a hot, humid environment with a lot of bark, and a substrate with dried leaves. When I took out all roaches and did a thorough overhaul of the terrarium, there was a lot of fungi in the substrate and the wood tended to rot at the fringes... no good. The new setup consists of slightly moist coco peat and a lot of bark pieces on top. I provided better ventilation as well to reduce air stagnation. Basically I will try the classic 'moist corner' setup. Water is provided through fruit and agar blocks. In any case, the roaches are now much more active at night and walk over the whole area. They eat well (fruit and a leaves/grasshoppers/fish food paste smeared on bark). Keeping my fingers crossed! Do other people have similar experiences with keeping their roaches too humid and/or with too little ventilation? In particular with rainforest species? How did you solve it? Is moisture a real problem for roaches?

    Two Schizopilia fissicollis roaches died

    I did set up a second enclosure with moist cocopeat soil and a lot of stacked pieces of bark (both vertical and horizontal). A very well ventilated lid on top. After that I transferred around 12 animals to the new enclosure. It was a good opportunity to check my population. The inspection showed that I have some adults, and a lot of nymphs of at least 3 different stages. In my setup, the inter-generation time is around 8 months. And it turns out that the first generation gave at least 3 batches of young before they perished themselves from old age, with around 10 young in each batch. So if all goes well and assuming only little loss along the way, I should be able to crank out a decent colony within a year. Keeping my fingers crossed....

    Articles for Invertebrates-Magazine requested

    And what kind of articles do you need? How long? written toward what kind of audience? Scientific viewpoint? Or rather experience based information? Do you need additional photographs etc. Could you give some clues? I'm not familiar with the magazine.

    Two Schizopilia fissicollis roaches died

    Some update, as it has been brought to my attention that Schizopilia fissicollis isn't doing well in captivity for a lot of people. Mine are still going strong, but that are a bit picky when it comes to their habitat it seems. Here is what I do and what I learned: * How I keep them: - pure cocofiber at the bottom, slightly moist. On top of that some stones. On the stones I have a pile of dry pieces of bark. - I feed them fish food and some fruits. - I rarely mist the enclosure - I do not heat the enclosure. - There is plenty of ventilation in the system. - I keep disturbances to an absolute minimum. * What I learned: - They are sensitive to mold. - They do not need a lot of moisture, although they tend to hide in the slightly more moist lower parts of the bark pile. - They like fruit and eat a lot of fish food. I keep the fish food dry and I make sure that the fruit is never molted. I'm planning to set up a larger second enclosure to ramp up their number. Anyone else experience with this species?
  12. Today I saw a female Pseudoglomeris magnifica roach walking on the front glass. And upon close inspection I saw, much to my delight, three small nymphs clinging between their mother's legs. (picture is rather dull, due to the anti-reflection cross-polarization filters I had on my flash). I'm very happy with this!

    Freshly molted Archimandrita tesselata

    Always beautiful to see! Wish there was a species that stayed that color, it would be an angel-like roach

    Pseudoglomeris (Corydidarum) magnifica

    A little over 3 cm / 1.2 inch.
  15. I managed to make some photographs of my new roaches: Corydidarum magnifica. The nymphs are still quite small (8mm / 0.31inch) and I took the photographs through the glass of their tank, so the quality isn't optimal.

    Managed to take some better pictures, couldn't withhold these...

    Mulberry, grape, fig, hibiscus leaves?

    Every fall, just when the leaves have dropped, I visit the nearby forest to collect fallen oak leaves. I sterilize them in a microwave oven, dry them and put the in vacuum bags. That way I have fresh, ready to use leaves. I do add then to the enclosure of most of my species, but most only nibble at them (Therea bernhardti, Lucihormetica verrucosa, several Polyphaga species). However, some actually eat a lot of these leaves: Archimandrita tesselata and Hemiblabera tenebricosa, for example. Most of my species prefer the leaves to be a bit more decayed. Which will happen anyway if the leaves stay moist. But for those, I often go back to the forest after a while, when the leaves on the ground have started to rot and decay. So yes, roaches do fine on oak leaves. In my experience, some prefer them freshly dropped leaves, other prefer more decayed leaves.

    How often do you feed?

    I feed my 20 roach colonies about 2-3 times / week. It includes misting, replacing fruit/carrots, adding some water to corners if needed etc. Some I take a daily look at and do maintenance when needed (Pseudoglomeris magnifica and Schizopilia fissicollis for example due to their high investment costs and being hard to get). Others I tend to be more careless about, as they can deal better with scarcity, like the Polyphaga species I keep.

    Care for Loboptera decipiens?

    I have a well established colony of this species. At first I kept them too moist. I almost lost the colony at that time. After that I cranked up the temperature and start keeping them nearly bone dry. Some misting every few days, sometimes a bit of water of water in a corner. Carrots, fish food, slices of apple... Cocopeat and crushed dried oak leaves. And that made the colony thrive. I now have taken away the heat source and I keep them at room temperature. They do great. So my conclusion is that these critters prefer a rather dry habitat with occasional mistings. Their reproduction accelerates with higher temperatures, but room temperature (and likely below that) works fine.

    Dipteretrum hanstroemi pictures and video

    There is a roach with ooth in the video I posted above, around 1:00. They are not very tiny (compared to the adults that is).
  21. I finally took the time to photograph some of my Dipteretrum hanstroemi roaches. I had to take some precautions, because of their skittishness and good climbing capacity, but I managed! It's still not clear to me what 'pest' capabilities they posses. Do do not fare well at lower temperatures (< 20C / 68F), but can do quite well in dryer habitats. They can climb well, and have a high reproduction rate. So far I have managed to keep them contained to their enclosure... Video will follow soon!

    Ancaudellia hamifera

    Finally got these roaches as well. They are still quite small, so it will take time to see adults. @Manuel_P: Have your roaches reached adulthood? Babies already? The adults cut their own wings. Have you seen that in your's?

    Dipteretrum hanstroemi pictures and video

    They indeed prefer a dry and warm enclosure. I almost lost them when I kept them more moist. They do like carrots and fish food and an occasional misting. That combined with some heating seems to do the trick here. I keep their substrate bone dry.

    Pesticide removal

    I always peel fruits before I give them to the roaches... Or when possible use those from my own garden. @Xenoblatta: these roaches died after eating contaminated fruits?

    Pesticide removal

    Most likely it contains permethrin. That stuff is quite persistent. I would put it in a washing machine with sodium carbonate instead of detergent and wash it a high temperature. Perhaps that will do, as permethrin hydrolyses under alkaline conditions. Another option is the combination of water and light... but that might take time. Even then, I would be reluctant to use it. Considering the fact that permethrin treated clothing can outlast many washing cycles....
