 There are a few hypothesis as to why this process may occur, one of them being that several sperm translocations may be needed to achieve full insemination.After this process is done and the female has successfully fertilized her eggs, she then lays them.The male is usually still attached to the female at this point to stop other males from removing their sperm, although sperm removal is harder in "C. scitulum" as they do not have the spines on the horns of their penis as other damselflies do.
