The Blattodea culture Group (BCG) is a worldwide group of cockroach enthusiasts and amateur and professional entomologists. As well as content generated by the Group this site uses a taxonomy provided by the Blattodea SpeciesFile to display information from numerous resources on one page (use the Taxonomy Search or browse the cockroach taxonomy.

The Group publishes a full colour journal, Cockroach Studies, which is distributed to members. Members of the group also have access to free livestock (for a list of species that have been in culture see the BCG Culture List) and are able to attend the Group's meetings.

The BCG also runs The Cockroach Forum, an online discussion board for all things to do with cockroaches.
