Madagascar Hissing Cockroach

Gromphadorhina portentosa

Reptiles Alive Name: Too many to name

Hissstory: Our first few hissing roaches were donated to us by Long Branch Nature Center in Arlington, VA.  Within a few months, we had lots, lots more.

RA Diet:
 Chopped leafy greens, vegetables, monkey chow, dog food, fruit, leftovers. (Hey, they are roaches they like leftovers!)


Natural Diet: Roaches are scavengers – they will eat dead and decaying plants and animals laying on the forest floor.

Range: Madagascar

Habitat: Hissing roaches live in the tropical rain forests of Madagascar.

Hissing roaches are a relatively a large roach, growing to about 3 inches.

Lifespan: Hissing roaches live for about two years.

 Male hissing roaches have two large bumps on the tops of their heads. They use them to battle for females just like goats do. After mating, females will keep the eggs inside her body until they hatch. Gestation is 60-70 days. Females have about 30 young

Conservation: Cockroaches are one of the most important species on our planet!  As decomposers, they create soil by eating decaying plants and animals.  Without decomposers like cockroaches, plants and trees could not grow.  Without plants and trees, animals and humans could not survive.  So, you might not want to live with, hug, or kiss a cockroach, but cockroaches are a super important animal.

Cool Facts: Hissing roaches produce a hissing noise by pushing air through holes in their abdomen. There are at least five different hisses.  Different hisses are used in courtship, to defend territory, and warn of danger.

We had a great experience with Reptiles Alive for my daughter’s 6th birthday party. Rachel arrived exactly on time, set up quickly, and immediately engaged the group of curious children. We had an impromptu dance party while waiting for last minute guests and Rachel was very accommodating. The children LOVED the show!! And my soon-to-be 11 year old wants them to come for his birthday! I highly recommend Reptiles Alive for your next event!read more

We just had Reptiles Alive come to our preschool and the kids loved it!! We had 4 shows over 2 days to accommodate all our children and everything went great! Caroline was very easy to work with and quick to respond to all my emails. She was our presenter too and was early each day and ready to go when the kids arrived. She really geared her show towards our audience (2-5yr olds) and had them laughing and answering her questions and touching the animals. It was perfect… we would definitely book them again!!read more

We booked Reptiles Alive for our son’s 7th birthday party. Miss Rachel put on an amazing show for the 20 kids we had over. The highlight was when my son and I had the chance to hold a long and surprisingly heavy boa constrictor named Sunflower. The show was both educational and fun for the kids, and it kept them captivated for a full hour – priceless!!read more

We invited Reptiles Alive for our birthday party. Ms. Rachel did a wonderful job to educate the kids about the fun facts of Reptiles and also kept them entertained and focused. It’s not a easy job facing a bunch of 7-year-old boys and 3-year-old preschoolers. We highly recommend Reptiles Alive show. It’s fun and full of knowledge!read more
