The Arachnid Queen in the "Roughnecks" series.
The Queen of a Bug colony is the progenitor of the colony, whose sole function is the production of its members. In the film, no Queen is mentioned. In the novel, during the course of a mission attempting to capture queen and Brain Bugs, the bugs kill the queen rather than allow her to be captured. The TV series presents a single bug queen as the ruler of all the bugs.
