Approximately .5" in length, and a great choice for juvenile bearded dragons, leopard geckos, and chameleons. Our Medium Dubia are about the length of an adult cricket, but heavier. We do all counts by weight in grams and we always weigh heavy to insure over count for dead and undersized Dubia. We do not ship Dubia to Florida, Hawaii, or outside the US. All Dubia nymphs are a mix of male and female; not sexed unless otherwise specified.
