  1. Yes, thank you. I haven't seen this being mentioned anywhere. More of my boxes were inspected this summer than last year. Most still went through and reached their destination, especially those with arachnids, but I think there has been some change in the inspection protocol. On the other hand, there were some nice organized imports to the US this year using Reptile Express, like the velvet worms.


  2. I guess I should update this thread.
    After some discussions with @Hisserdude, and in light of a new scientific paper, it appears that this species is NOT Hormetica apolinari, but Hormetica strumosa.
    I am not afraid to admit when I am wrong when there is enough evidence :) so I will change all me labels from now on, and you should do the same.
    Unfortunately I cannot edit the thread's title.. but I will put a notice in the opening post.

  3. It might not be hot news, but I thought I'd share a new cockroach that I started breeding. Even when it comes to mainstream species, I always prefer to work with wildtypes (meaning strains that originated from known, wild populations) because I feel there is often too much mixing and hybridizing in the arthropod hobby, leading to weaker captive populations.
    Nymphs of this roach were collected in a small Honduran cave as an unidentified "Blaberus sp.". It appears to be a variety of Blaberus giganteus, with wide black banding and a darker color tone. Adults begin as white individuals but very quickly turn orange.
    The funny thing is that I never planned to keep B. giganteus. I avoided them due to their bad reputation - low tolerance for crowding and cannibalism. But this strain seems to be ok with it, I still have all the original adults sharing the space with hundreds of nymphs, and while their wings are no longer intact (well, they use them for courtship after all), they are still kicking. They seem to be very hardy.

  4. This is great news and definitely a step in the right direction. I share your notion that Megaloblatta's oothecae are tough like bricks and must go through some kind of process in order to hatch.
    What was really interesting for me to read were the observations on diet preferences between adults and nymph. This means that they possibly occupy different habitats in the wild. Maybe the nymphs have a specialized diet, or are associated with other insects (termites, fulgorids). Another option is that they stay close to the mother and she directly feeds them or prepares processed food for them. I am not sure I would go this far, but it is not too far fetched when talking about cockroaches.
    In any case, well done on hatching them and I hope they do well!

  5. Yes, this is typical (also for Lanxoblatta), and one of the reasons that proper bark of good quality should be used with them, as opposed to cork.
    You can see in the photo I posted below that they slowly degrade the substrate, first by creating pockets for them to sit in, and then by actually making holes.

  6. @Xenoblatta when I said pupae, I meant crushed pupae, to give the roaches an easy "start". They did not respond to other "prey" for me. They definitely don't go after live and active prey, because they are not built for it. Yes, you can say they are opportunistic - will eat whatever they stumble upon. Want to see something cool? Try to give them bird droppings, most chances they will take it. Mine were P. bilunata, a bit bigger than yours, but I did not succeed with the oothecae.
    Be careful with aphids as some feed on poisonous plants and are therefore toxic.

  7. Fantastic stuff. I've had Paratropes for a while (not this species though), and I agree with the idea of offering pollen - they seemed to like nibbling on it. I have also had success with giving them beetle pupa. You wouldn't expect them to take on prey but they never refused. Like @Hisserdude said, the bottleneck for me was hatching the oothecae. I did not get enough of them so I could not experiment properly with different conditions required for hatching.
