Elliptorhina javanica - Halloween Hisser

Distribution:

Madagascar

Description:

Halloween Hissing Cockroach a.k.a Halloween Hisser a.k.a.  Elliptorhina javanica. These are a rare roach in the hobby due to being new in the hobby. They are docile in nature and calm temperament make for an excellent pet. Something nice of this species is that they do not have the heavy spine rear legs like the common Hissers. This makes them more handle able for young kids getting into the hobby. As their name implies, hissers can make a very audible hissing sound. They do this by exhaling air through their breathing holes.

Size:

1/4 inch when born, adults can attain 1.5 inches in length

Sexing:

They are sexually dimorphic, that is to say that the adult females look completely different from the adult males. Mature male and female Halloween hissers are easy to sex. The male has horns on its head and the females do not. They will produce the horns as they get older so younger nymphs are harder to tell apart. You can also tell the sex in large nymphs by look at the last two ventral sclerites. In females they will be fused or one and males it will be 2. See the pictures on the left. 

Lifespan:
2-3 years on average
 
Difficulty Level:
easy/moderate
 
Caging:

Hissers can climb glass and plastic so a barrier is needed or an extremely tight fitting lid. I like to house all of my roaches in Rubbermaid or Sterlite containers with screened lids and a roach barrier to contain them. I use a roach barrier of either Vaseline or food safe grease.

Substrate:

I use egg crates positioned vertically for additional floor/living space with a substrate of peat moss and oak leaves. Other soil mixtures can be used like coco fiber. If you use any kind of substrate from a hardware store or garden shop, MAKE SURE IT IS FERTILIZER AND PESTICIDE FREE!

Required Temperatures:

82 - 90 degrees F

Humidity:

40%-50% you can keep a spray bottle handy to help keep humidity up in drier areas. If you use a substrate wetting it down periodically can help maintain proper humidity as well.

Food Requirements:

Like most roaches, hissers are decomposers, feeding on ripe fruit and other plant materials. I keep my home made dry roach food available to them at all times. When feeding any fresh fruits or vegetables, do not put in more then they can eat in 24-36 hour period to avoid problems caused by rotten/moldy food.

Maintenance:

Keep food and water available at all times. Clean out the waste as needed.

Breeding Notes:

They are easy to breed. The average is 15-20 babies at a time, but they reproduce at the same rate as normal hissers.  Hissers are live bearing.
