  1. The white color is cleaner on the upper side, and the underside is more ivory-yellowish. It is difficult to get their true color to come out nicely in the photo as in real life. I did not want to use a flash because then the pale color would be blown out by the flash (not to mention these roaches are glossy).

    They are white in real life, but as they age the white turns into ivory-yellowish, especially at the base of the wings.


  2. They are slightly bigger than P. nivea. Females are 2.5cm long, 3cm with the wings.

    Hisserdude - it is illegal. Luckily, they are in a facility that meets the quarantine requirements. There is a slight advantage with these being a potential new species - they are not listed as pests (or anything else, for that matter) in any risk assessment...

    While I do not wish to turn this thread into a discussion about control of exotic species, some regulations are justified. It is true that Canada is severly cold in the winter, but for this reason potential pests will tend to stick around inhabited areas where there is heating and food. That said, I do agree that some species have absolutely no way to establish in Canada. I never understood why some tropical insects are forbidden, especially stick insects.


  3. I second what Roman Buck said - at least for P. aegyptiaca - use fine sand, and keep it dry. They will get all the water they need from food (fruit and veggies).

    As for the oothecae - they take very long to hatch, I had mine hatching after 10 months-1year. I separeted them from the roaches and kept them in a box containing woodshavings. I added just the tiniest bit of water for humidity, about 10%, kept it constant and waited. After they hatched, I transferred them with the adults as they tend to grow better with bigger specimens munching on the food first.


  4. Good suggestion Thomas, I thought about it too - but when I looked closely at the famous Xestoblatta sp. photo I found some differences.

    In Panchlora nivea and this unnamed white species, the wings and the pronotum have a wide transparent margin. In addition, the pronotum is oval.

    In Xestoblatta sp. it looks like the wing margins are yellow (probably with a very thin transparent part) and the pronotum too has a very thin transparent margin. And the pronotum shape is completely different, it looks almost triangular. The pronotum shape itself might be enough to determine that the white roach does not belong to genus Xestoblatta.

    Here are some photos for comparison (not mine):

  5. I am new here in this forum (haven't even introduced myself), but I can confirm this species is entirely white -

    Last september I visted in Belize for a workshop and found a female of these white Panchlora sp. (although it is possible this is a different genus). I will see if I have a decent photo of it - and will post later.

    I intend to return to Belize for scientific work (on a different group of invertebrates) this time with collecting permits in hand. I cannot wait to collect this beautiful roach and verify which species it is.
