Oniscus asellus "Mardi Gras Dalmatian"

Very tasty-looking.

The Dalmatians on bugsincyberspace only have a few pathetic white flecks, so I like them a lot.

Thanks! :D

Yeah, lots of Porcellio Dalmatians in the hobby are white with very few, tiny grey flecks, there aren't that many that I've seen that look like they deserve the name "Dalmatian", more like "White speckled" or something. I really like these Dalmatian Oniscus because they have a more balanced coloration between the white and the grey, (and even a little yellow here and there). 

 
Update on my culture, the isopods all developed normal color resembling normal colored adults up until around 1/2 the length of an adult when around half of them began showing abnormalities, I have now noticed every molt they lose pigmentation and some have gained maybe 2 or 3 black spots and I also have some specimens who are very light grey especially towards the front half of the body. If all now oddly colored specimens keeps developing like this they could resemble my original female in a few molts. This could also mean these aren't the same gene but instead have a different one with similar end result. I will keep everyone updated.

Here is an abnormally light animal especially near the front, I'm not 100% certain they will become like my adult but I know they were darker a few molts ago.

Here is a close up of what I discovered to be a dark pigmented spot that showed up on another light isopod, I did flip it over to check if it was Dirt and gently swabbed the spot on both sides, definitely part of the coloration.

Doesn't look like they are gonna be Dalmatians man, though I could be wrong. I've had many offspring from normal O.asellus look like the individuals above, but they normally don't get much lighter than that. I've also had offspring come out bright orange at first, but as they get older they almost always turn a grey-tan color. It's possible they could become Dalmatians when they are older, but I highly doubt it.

That being said, they may still carry the Dalmatian gene, so their offspring could come out looking like Dalmatians, you never know!

 
Yeah I'm not sure, the middle one does have a black spot though and these at lighter than my others by a good amount who knows, most isopod morphs are recessive anyway

Thanks for the update.  It will be interesting to see what develops in your colony over the next few generations!  Good luck!!

 
Yep, I'm closing in on generation 2 now with all the first gen offspring from the first male being near mature. The offspring from the second male are also getting close to developing color so I'll see what they look like and she is carrying offspring from the third male now. I have been switching males every time I find her carrying offspring to promote a larger gene pool in my colony and I will continue outcrossing this strain if it proves out, since so far all juveniles in the colony have the same mother and I am restricted to 3 males.

 
I definitely would like to test breed and see if these two strains can produce dalmatian offspring too or if it's two separate genes doing the same thing. So as soon as I have mature adults showing visual for the gene I'd definitely like to get my hands on at least one or two males from your colony if possible.

 
The animals previously photographed have matured and began breeding and are definitely not Dalmatian but aren't normal either, they have a sort of tan color and when I isolated 2 of them they have produced a good amount of Dalmatian offspring. My colony may be a co-dominant trait.

Interesting, definitely seems to be different genetics at work than in my strain! :) Keep us updated on them!

 
@Hisserdude I'll keep you updated, you also have said you have had lighter animals pop up in your strain so maybe the lighter animals are related to the Dalmatian gene. I'l try and get a comparison shot between one of the second generation offspring with the sort of tan color I'm seeing and my normal male later.

The isopod in this post actually has developed another black spot and abnormal gold flecking, but has an orange/grey/tan base color. Its like it has the spots of the Dalmatian isopods except with a tan base color and not white.
