Already taking into consideration some of the obvious characteristics found in Yuki-Onna, sexual involvement in consuming the 'Spirit' of a unsuspecting malewith sexual temptations, I began to relate this automaticaly to how a 'Praying Mantis' would devour her male counterpart in the midst of sexual reproduction, and after searching for the term, discovered it was refered to as 'Sexual Cannibalism'. So I decided to do a bit of research into the subject.
Sexual cannibalism is a special case of cannibalism in which a female organism kills and consumes it's male counterpart before, during, or after copulation. Although other forms of cannibalism are widespread across animal classes sexual cannibalism is a taxonomically rare phenomenon. It has been documented only arachnids, insects, and amphipods, with some evidence for its occurrence in gastropods, copepods, and cephalopods.
Despite its overall rarity, sexual cannibalism is common in many families of spiders and scorpions, and can have important effects on population size, sex ratio, and even persistence. In most species in which it occurs, the female usually cannibalises the male, due to the large size of the female as a result of dimorphism.
Doing the rounds of research, here's a list of creatures that have been known to take part in the act:
Red Back Spiders
Nephila Plumipes/Golden Orb Weavers
Without going too far into the subject and over complicating the influence, taking this theme into consideration, I feel this could somewhat lend itself to a design aspect of Yuki-Onna, by using imagery that is with related to these specific creatures. This will will help evoke feelings associated with 'Predatory' nature of Sexual Cannibalism, such as sexual empowerment, dominance, weakness, fear etc.
