The false labeling of wildlife charge carries a maximum penalty of five years in prison and a $250,000 fine. On June 20, customs officers in Indianapolis intercepted a Federal Express package addressed to Lapkiewicz containing live giant millipedes. And on July 3, fish and wildlife agents at John F. Kennedy International Airport in New York intercepted a package with 245 small containers with live orchid mantids inside. Authorities say Lapkiewicz was twice warned about his actions, and federal investigators eventually learned he was selling the creatures through his Facebook page."

Your best bet is to find wild populations and hunt for orange or calico specimens. With your current method it might take you decades or you may never seen an orange as long as you live. You can only isolate a gene that exists within the specimens you have. You can't expect to pull them from a stock without the gene. It might be there and it might not. Orange are common in the US but they are probably all from ones I isolated and traded in the 90's, but I started with one orange. Calico will be a byproduct of isolating the orange but it is very difficult to isolate the calico because it is more than one gene. Isopods aren't terribly predatory unless the food doesn't move like a pupa.

Cleaner beetles are a threat but mostly if the population is excessive.

Welcome! I still have not picked up any of those Gyna centurio, how is your culture doing?

They certainly can associate the food bowl location and they have a great sense of smell so they probably smell the food and go for the bowl even before you put it in there.

I think pretty much anything you can find is introduced except the littoral species.

Articles primarily on husbandry for various invertebrates are needed for future issues. Articles on tarantulas, centipedes, and scorpions are especially needed. Share your successes!! Unlike most journals there is no cost to publish and free copies or subscriptions are provided to authors who provide accepted articles. In addition to invertebrate husbandry, articles have included invertebrate biology, venoms, field collecting, enclosure design, etc.

Are you sure they are fungus gnats and not phorids? I know it's hard to keep phorids from roach cultures but fungus gnats seem to be unlikely except for rhinos or polyphagids where you build up wet decomposing leaves over time. You can try staying away from leaves for anything that doesn't really need it.

These are kept more like lepidoptera larvae. I've found adults in the past but did not get them to lay eggs on the host.

Chrysomelids are almost never kept. I've only seen larvae of a few different species a few times in my life. These are from the biggest species in my area (1/2"). This is a '"common" species but I'm not certain I've ever seen the larvae before except in photos. Last time I found some chrysomelid larvae was about ten years ago. They were on a small cottonwood or aspen tree and I went back to grab some the next day, but something had eaten them.

I suggest no panic.

There is an article, called Terrestrial Isopods, in the Sept. 2004 Invertebrates-Magazine (pages 9-12) about keeping isopods as pets in the United States. The orange form of Porcellio scaber is featured (2004 cover posted here), but the article also discusses the 'calico' form of the same species, white micropods, a few normal species and the iridovirus. The article conclusion: "Terrestrial Isopods have grown common as 'cleanup crew' and are gaining popularity as feeders for certain animals. However, unless someone finds a large species or can figure out how to grow them to 2" (even 1" would be great), they'll never become a popular pet. Still, there are some interesting species and the orange and blue forms are attractive." The same article was greatly expanded and added to for the isopod section in the 2011 book, Invertebrates for Exhibition. The same person wrote the 2004 article, the 2011 I4E chapter, the small paperback Isopods in Captivity early 2013, and the large Isopod hardcover book published late 2013.

Someone in the USA wrote a book about the isopod hobby 5 years ago. There is evidence the isopod hobby started in the late 1990's in the United States with a hobbyist who isolated orange Porcellio from Spain and offered them for terrarium keepers regularly in the US arthropod hobby circuit, but there really was no hobby before the 2013 Isopods in Captivity book.

They are good food for the large African assassins, certain turtles, and large monitors.

Glad there are resources these days.
