Megaloblatta blaberoides

Güten tag, alle!

 A few days ago, I started my very first big project. I obtained the unique opportunity to culture a new species of roach in the U.S hobby, and it isn't just any roach. Thanks to Kyle from Roach Crossing, I'll be attempting to introduce Megaloblatta blaberoides, the world's second largest roach species (by wing span and body length). He owns a captive female that was pregnant and produced two ooths. I received the second one, and I'll be attempting to hatch it. The U.S hobby has not seen any Megaloblatta yet. This is hopefully the first day of change for that!


 The challenge for me is experience. Though I do have a couple of intermediate-level species that I've hadn't had an issue with, I still haven't fully grasped proper humidity. Most of my keeping experience is with dry-tolerant species. I believe what I'm doing so far is correct. Having a thermostat that reads temperature and humidity helps me remain confident that things are going well. It also helps that RC sent the ooth with already-damp substrate that I could just transfer over to the ooth's new enclosure.

 I don't want to disturb the ooth after I already buried it, so here is a snapshot of RC's female holding it before she laid it

 
 
The laid ooth is much darker, as it hardens after being laid. If you'd like to see the actual ooth itself, visit my instagram to see the unboxing and setup video!
 

 So what's next?
Well, the only thing to do now is keep the humidity and temperature parameters consistent (that being 80% humidity and 77-86 degrees Fahrenheit (25-30 Celsius)) and wait for it to hatch. I'll check on it once a week to make sure it isn't rotting. Which is another thing I don't have much experience with... the only other species I've worked with that are oviparous and lay ootheca are N. rhombifolia, who only recently laid their ooths. They all look fine, but I've never seen/personally experienced a "dead" ootheca (dried out or rotted). With the help of the community, though, I'm confident it'll be fine. :) Speaking of, Roach Crossing and InvertebrateDude are due credit for getting this project started for me. InvertebrateDude supplied the husbandry information, and RC provided the ooth and resources, so I'd not have been able to do this without them. As an amateur roach-keeper, I'll be updating them regularly on the ooth's status.
 
This venture will take approximately a year. I know that sounds so long! But what can you expect from a super-sized cockroach? Even after it hatches, the nymphs will take approximately a little over a year to reach adulthood, then of course comes the challenge of breeding them, getting them to lay their ootheca, and waiting for those to hatch. So altogether, introducing this species is going to take a long time, but with plenty of patience and support from the community, we'll make it happen!
 
I'll of course keep you updated on here, but for faster and more accessible updates, be sure to follow my instagram. 😊I also plan on starting to stream on the Off The Fent Roaches Youtube channel for live husbandry and other things involving my roaches, so be sure to subscribe over there! I really appreciate your support.😊
 
As always, any feedback you want to give me or if you need to contact me feel free to do so by emailing me at offthefentroaches@gmail.com.
 
Auf weidersehen!
