The scientific name of Dubia Roaches is Blaptica dubia. They are more commonly known as Orange-spotted roach, Argentian Wood roach, or Guyana spotted roach. They are a very popular feeder for numerous amphibians, fish, reptiles, and arachnids.
Beginning in Costa Rica, they are found in South and Central America. They are common from Brazil and French Guiana to Argentina.
They have a very high nutritional value, having rich quantities of proteins. Their nutritional value makes them a superior feeder as compared to crickets and worms. They are easier to keep owing to their inability to climb smooth surfaces or jump, the rarity of flying, and slow movement. They are also more mobile than mealworms and super worms for a more efficient feeding response.
They are a species of cockroach. They can grow to become about 40 to 45 cm in size. Body of the adult male is covered with full wings while adult female possesses tiny wing stubs. Their forewings also called the Tegmina, is about a fourth of their entire body length. Dubia roaches are dark brown to black in color with lighter orange stripes or spots on their bodies. These patterns are only visible in bright light. The color of these roaches varies with diet and environment, from one colony to the other.
The ideal temperature range for dubia roaches in between 24 and 35°C. Below 20°C, they will not breed. Moreover, if the humidity is very low, they will not be able to molt successfully. Unlike many roach species, dubia roaches can tolerate low humidity. They sequester a significant quantity of water in their body through feeding on fruits. This stored water is released during stress conditions.
Sexually, they are dimorphic. Dubia roaches are partially ovoviviparous. They give birth to live offspring after their eggs hatch inside the female body. An adult female can give birth to about 20 to 40 nymphs per month when the conditions are favorable. The pregnancy lasts for 48 to 64 days. The eggs are enclosed in an ootheca; each ootheca holds 20 to 35 eggs.
Although adult males have fully developed wings, they are rarely known to be able to fly. They also have a pigmented musculature like that of typical cockroaches which allows them to meet the energy requirements needed for a sustained flight.
Dubia roaches cannot climb any surface that is vertical and smooth because their arolium is not developed. Juvenile dubia roaches are capable of climbing silicone and plastic surfaces, like that of sides of a plastic container.
The dubia roaches are frugivore, which means they prefer grains and fruits. They shun away from high protein sources such as meat. They have a particular preference for the vegetable matter that is semi-sweet.
Female dubia roaches live longer than males. An adult dubia roach lives an average of 1 to 2 years.
Dubia roaches are an extremely popular feeder insect due to easy management and high nutritional value. They are the best option for people who want to keep their pets in the best possible health.
