Lesson plan

Cryptocercus

Cryptocercus is a genus of Dictyoptera (cockroaches and allies) and the sole member of its own family Cryptocercidae. Species are known as wood roaches or brown-hooded cockroaches. These roaches are subsocial, their young requiring considerable parental interaction. They also share wood-digesting gut bacteria types with wood-eating termites, and are therefore seen as evidence of a close genetic relationship, that termites are essentially evolved from social cockroaches. Cryptocercus is especially notable for sharing numerous characteristics with termites, and phylogenetic studies have shown this genus is more closely related to termites than it is to other cockroaches. These two lineages probably shared a common ancestor in the early Cretaceous.
