Some of my beauties

Recommended Posts


I want to show you some of my more uncommon [here in Europe] roach species.

My foto size reduction is slightly better than in my last topic and I will further try to 

improve this.


Melanozosteria nitida BRUNNER VON WATTENWYL 1865 (from Khai Sok in Thailand)

Only under lights more redish than black, but look at the defensive secretion on their last abdominal segments.

They are incredible fast runners.



Thorax porcellana SAUSSURE 1862 (from India and Sri Lanka) 

Beautyful species from the Epilamprinae subfamily. Most fascinating are the 

baby cockroaches below their mothers wings for the first weeks. 

First rank breakout artists.

How is the care for Thorax porcellana  like? 
Food, substrate, temperature, moisture etc. 
Do the nymphs borrow in the soil? Are they active during the day, or the night? 
How big are the adult? 

Just asking, because I'll get this species soon.

They are  more sturdy than I thouht and relative fast breeders.

I started with 10 in all sizes. 


Temperatures I have at 27-28°C and humidity high, 70-80%  (rain forest climate).

They are night active and hiding in the day.


Food like all my other roaches - different sorts of fruits and vegetables, dry cat food with oat flakes. 

They like to eat hazelnut leaves and the bark of young twigs (a real personal tip, some species eat this more

than everything else). Beech and oak is ok, too. I think they eat a lot compared to many other species.


The young nymphs like to hide in the rolled, dry leaves. This reduces climbing and hiding in the slit between 

box and lid. They squeeze through real small openings and run over vaseline layers like they would not  

be there. Olive oil is better. Redundant to mention - all stages are glass climbers.


Substrat only 2 or 3 cm, I take coco humus.  A quarter to a half humid, the rest dry. If it gets too dry the young

nymphs could die. And no, not the adults nor the nyphs do burrow.



N1 approximately 3mm

Males maximum a bit less than 20mm

Females maximum a bit more than 25mm


I wish you a lot of fun and good results with the Thorax!


Greetings, Marco
