Allpet Roaches

Genetic deformities

Recommended Posts

Genetic deformities in roaches are rare and often once in a lifetime events, such as the hisser Gyandromorph depicted on the Allpet Roaches main page. While such deformities tend to be undesirable they usually can't be bred for anyway since the individual is incapable of reproducing. The following is a rare mutant of Blaptica dubia. At a glance it seems like an interesting mutation due to the white sections but on closer inspection the legs on the white side are deformed and the mutation is a result of bigger problems and not just a color issue. Unfortunately this animal died.

Yeah I saw that on Arachnoboards, very strange. I have a roach with 1 or 2 feet that are lighter than usual in color, almost a yellow-peach color, really weird. Its hard to get a picture though it's fast and I cant hold it still without injuring it.

Hmm... I've always held to the thought that colonies need their genetic material refreshed once in a while, hence is why I purchased some nymphs from a local show to "replenish" my hisser colony.

Whoa.

I just checked my hissers today and thought this girl was molting, then I realized she wasn't. Won't she be able to reproduce?

That's actually a pretty common deformity in hissers. I've seen it on giant stock and tigers. It may be sex linked because it seems like only females have it. It probably does not affect reproduction but it's the kind of deformity most people would feed off or at least isolate to prevent breeding. Also, someone just posted their photo on another thread.

Check out this Hisser Nymph deformity.It looked fine before but after the third molt got this way.Is this due to inbreeding or some extrenal factor like temp,food,humidity or maybe overcrowding :unsure:

I can't see your photos, they don't open.

I've seen that deformity in hissers and I think it's due to damage, not a genetic cause. Still, wouldn't hurt to isolate that one and see how it looks in a molt or two or at adulthood.

That's really odd. Do you know if the white part of the exoskelton was "cured" at all or was it just pliable like after a normal moult?

Hey Orin,

What is the other thread that the below picture come from?

Yes,you were right,the nymph had an injury to the exoskeleton

before the molt the chitin looked kinda healed and not white

but after the molt the damaged chitin fell off

Well, now we've got some scientific knowledge!

This is great, we as a community on the cutting edge of the hobby! So exciting!

We've disproved the sex-linked idea, seeing as the above roach is a male.

Woo. We rock! XD

I've seen the same type of segment deformity on a red and black roach and even on millipedes. Here it is on a tiger hisser.

Here's a millipede with the same type of segment deformation.

That's one of those fire millipedes, isn't it? One of my hisser babies had something like that, only much less noticeable. He died from that humidity problem I had, but it was still kinda neat. Also, one nymph molted 2 days ago and then hurt his leg. He's still that yellow color though, and he doesn't seem to be darkening. Why?

Actually that's a Vietnamese rainbow millipede formerly known as Aulacobolus rubropunctatus but changed to Tonkinbolus - possibly- dollfusi and we'll see if there are any more revisions. The fire millipede from Madagascar is much nicer looking and bigger.

Sickly animals sometimes have problems with the exoskeleton not hardening correctly.

He died as expected (but another molted to l4!). Thanks for the photo, Orin. Genetic deformities can make some pretty wierd stuff.
