Chemical and transcriptomic diversity do not correlate with ascending levels of social complexity in Blattodea

This paper examines cockroach (Blattodea) diversity, ecology, and evolutionary biology. Blattodea encompass cockroaches and termites, representing a major insect order with diverse ecological roles. We review current understanding of blattodean taxonomy, behavior, ecology, and the evolutionary transition from solitary cockroaches to eusocial termites.
