Reproduction and Life Cycle

At the moment, there is no published information in regards to Vertigo arthuri’s recruitment, survival, immigration, and emigration rates. The age at which they can first reproduce is currently unknown as well. Certain aspects of its life history remain unknown. Their life cycle is stage based without a stand time frame from egg until maturity. It may vary with environmental conditions. There are three stages of the Vertigo arthuri life-cycle: 1) egg or embryonic developmental stage 2) sub-adult or juvenile stage, and 3) mature, reproductive adult stage. Vertigo arthuri are hermaphroditic and therefore can act as either the male or female adult during mating (Anderson, T. 2004).
