Dubia Roach (Blaptica dubia)

Blaptica dubia, the Dubia roach, orange-spotted roach, Guyana spotted roach, or Argentinian wood roach, is a medium-sized species of cockroach which grows to around 40–45 mm (1.6–1.8 in).

Blaptica dubia is a popular feeder insect, particularly among tarantula, amphibian, reptile, and ant enthusiasts and owners. Keeping or breeding the insect is made easier by their inability to jump or climb smooth surfaces, relatively slow movement, and rarity of flying. They are also quiet, unlike crickets, and tropical environmental requirements reduce the likelihood of establishment of escapees in colder, dryer climates. B. dubia can cause allergic reactions in humans, although they produce relatively little odor compared to many cockroaches.

The proximate analysis of adults and nymph of B. dubia contained 59.06-62.70% moisture, 2.47-4.17% ash, 47.50-54.32%crude protein, 3.83-5.58 % chitin and 35.49-44.22% fat on dry weight.
