  1. Hello, this is Mark. I may have inquired about this once before but I thought I might ask around again. Are Formosa Sand Roaches still in culture? Seems like everyone who had success with them (including myself) experienced culture crash. I am hopeful to acquire a new culture and am interested to know if anyone still has them.
  2. You're right, it probably is a German Cockroach. For some reason, I misread Misa_oma's location being South Carolina, not NC. There are only a few scattered records of Asian Cockroaches being found in the southern part of NC so it likely isn't that after all. Sorry for the confusion.
  3. It looks like a subadult Asian Cockroach (Blattella asahinai) to me. It probably couldn't climb the inside of the vitamin jar if there was a residual layer of vitamin dust that remained or a petroleum film embedded in the plastic to prevent the pills from sticking. This roach has been reported as an outdoor pest (peridomestic) in South Carolina and the remaining southeast/south-central states. Subadults tend to have a slightly lighter coloring than the typical German Cockroach populations. If it's environment was disturbed during the roof cleaning, it may had accidentally found its way insid
  4. A systemic pesticide was exactly the issue but as I stated previously to only use organically grown house plants that you know are safe because the roaches may very well nibble on them.
  5. I wish that were true for captive specimens. I once set up an exhibit for 30 hissing roaches that had living plants native to Madagascar such as Madagascar Dragon Trees (Dracaena marginata), Blossfeld Kalanchos (Kalanchoe blossfeldiana) and Madagascar Palms (Pachypodium lamerei) to name a few. The roaches were still offered their typical diet and water sources they had received prior to being placed in the exhibit. Within days, almost all of the plants had been nibbled on with the Kalancho being completely eaten. Less than a week later, nearly all the roaches were found on their backs with leg
  6. I would be very cautious adding live plants to your enclosure without doing a considerable amount of research beforehand. First off, most house plants such as Pothos are potentially hazardous to both insects and mammals due to an abundance of calcium oxalate raphites in their leaves. Raphites are microscopic, needle-like projections that are designed to embed the gum tissues or stomach linings of whatever eats the leaves, causing severe discomfort. Although not deadly to insects themselves, the internal wounds sustained from their consumption may lead to secondary infections which could cause
  7. Alan, Since Luridiblatta are native to the dryer regions bordering the Mediterranean, I would keep them in a well-ventilated enclosure with a relatively dry to slightly damp substrate. As long as the air flow is good enough, the roaches might appreciate a light misting every other day providing all moisture evaporates over a half-day's time. I would imagine a similar setup you have for your Blattella vaga would probably be sufficient. My Loboptera decipiens which are from that same region, are fairing quite well kept this way. Most of their moisture comes from the sweet potato and apple slice
  8. It is believed that African Bullets are Neostylopyga propinqua and Giant Greens are Panchlora exoleta. I too believe to know what the Little Kenyans are but won't ruin the fun for Orin.
  9. From what I have read, heard and experienced, the two Cryptocercus species found along the southernmost part of the species range (C. darwini- central TN/ northern Alabama and C. garciai-northern GA) prefer lowland forests and are not as sensitive to higher temperatures as those found in higher elevations such as C. wrighti and C. punctulatus. An acquaintance of mine who lives near the range occupied by C. darwini stated that some of the largest C. darwini colonies he uncovered were found in sun exposed logs whose surface temps were well over 90 degrees. But in captivity, it seems these roache
  10. I'm guessing those are Arenivaga erratica. The only other similar Arenivaga species from Texas is A. tonkawa but the females are smaller and lighter in color. The males of both types look about the same except their genitalia. Please let me know if you ever have any to sell. Mark
  11. Sorry for the late reply but I thought I should add it anyways. This is a male (Compsodes mexicanus), a primitive blattarian member of the family Corydiidae (previously Polyphagidae); subfamily Tiviinae. Related genera include Austropolyphaga from Australia and Anacompsa from Africa. These are among the few genera of modern roaches that retained the presence of a "pseudovein" that runs diagonally from the radial veins up towards the costals on both forewings. Blattopteran "roachoids" and the earliest mantids also exhibited this feature as well. Fossil evidence shows that as roaches became less
  12. Hello, this is Mark. Blaberus identification can only be fully confirmed through genital comparison since many of them can be surprisingly polymorphic with some individuals exhibiting physical characteristics indicative of other closely related species. However, most Blaberus have a few specific visual, odorous and behavioral "tells" that can also be useful identifying markers. The photo is clear enough to see their stouter tegmina in combination with a larger pronotal "spot" suggesting that these are Blaberus fusca aka B. craniifer according to Roth. Also, the broader costal stripes blending
  13. I have been reading some literature from the Smithsonian regarding several genera of pill millipedes native to the USA such as Onomeris (Alabama,Georgia,South Carolina), Sonoromeris (California) and Trichomeris (Alabama). Just curious if anyone has actually seen any native pill millipedes in their natural state here in the US? I saw an illustration of Sonoromeris from California once when I was still a kid but that's it. I remember it appearing similar to Glomeris marginata from Europe. Mark
  14. I have seen B. giganteus populations that have the half-faced "grin" as well. I had some that I received from Barney at Hatari Invertebrates. Many populations lack the pronotal markings all together while some have a blended ratio between the two. There's a possibility that the two types may have originated from different regions in South America. The "grin" is likely a dominant trait since it is strongly exhibited by most members within the Giganteus species complex.
  15. Thick-leaved and shiny-leaved house plants usually have silica crystals imbedded in their tissues which may cause internal irritation and possibly infection. Ficus plants produce a mildly toxic latex-based compound that most insects naturally avoid. Most house plants that have tender leaves are perfectly edible to insects, however, my concern is that many greenhouses use soil-applied systemic insecticides which incorporate into the plant tissues through transpiration. Some of these compounds can remain active in the soil for years. Unless you know for certain that these are not present, I woul
