Life Cycle
multiple generations per year; mating occurs off the host and involves a unique form of copulation called ‘traumatic insemination’ whereby the male penetrates the female’s abdominal wall with his external genitalia and ejaculates into her body cavity. Adults live 6-12 months and may survive long periods without feeding.
Introduced from Europe by early colonists. Suspected, but never proven, of transmitting 41 human disease organisms(1); may be naturally infected with several blood-borne pathogens, but is not effective as vector
