It is known that spiders of the species L. Latrunculorum Cannibalis build immense (virtually unlimited) communities where members arrange in huge chessboard-like webs with black males and white females each surrounded by four individuals of the opposite sex.
At the beginning of the mating season, males randomly approach and court one of the neighboring females. Females only pair with one male, which is eaten after copulation. If approached by two or more males, females will choose one with no particular preference, and reject the other ones. Rejected males go back to their home locations where they have a chance to approach and court another uncoupled neighboring female, as long as there are any. The process continues until all mating possibilities are exhausted.
What is the highest possible percentage of male spiders who surivive the mating season?
